I . INTRODUCTION

The Sanitary Engineering Section of the Department of Health Ser-

vices conducted a statewide survey of wastewater reclamation fa-

cilities in May and June of 1978 . The survey covered wastewater

reclamation activities that occurred during all of calendar year

1977 and the first six months of 1978 .

This report presents the findings on 220 wastewater reclamation

plants and 363 use areas included in the survey .

The objectives of the survey were ;

A . To inventory wastewater reclamation facilities , includ-

ing the number of operations , the quantities of wastewater

reuse, and types of reuse in California .

B . To determine the current status of compliance with the

Wastewater Reclamation Criteria, Title 22, Division 4, Cali-

fornia Administrative Code .

C . To investigate the management ,operation, and control s

at the use areas .

II . DATA COLLECTION

The 1978 Wastewater-Reclamation Facilities Survey covered the 22 0

wastewater reclamation plants and 363 use area operations

comprising the total reclamation activities occurring in Califor-

nia during the calendar year 1977 and the first six months of

1978 . Data collection was accomplished by both field investiga-

tions and a mail survey . Information concerning wastewater rec-

lamation plants and use areas operations was summarized on a

written questionnaire . Two hundred and thirteen and 138 com-

pleted survey questionnaires were collected from the wastewater

reclamation plants and use areas , respectively .

1 . Treatment

Wastewater reclamation involves the use of a potentially hazar-

dous substance which should be managed with due consideration to

safeguard public health . Undue health risks can be adequately

minimized if the effluent is appropriately treated to the quality

levels as prescribed in the Wastewater Reclamation Criteria, Ti-

tle 22 of the California Administrative Code . The criteria esta-

blished the minimum treatment quality levels and treatment relia-

bility provisions for the following types of beneficial uses : Ir-

rigation of fodder , fiber and seed crops , orchards and vineyards ;

spray and surface irrigation of food crops ; landscape irrigation

of parks, playgrounds , schoolyards , golf courses and cemeteries ;

landscape and recreational impoundments ; and groundwater recharge

by surface spreading ( l) . (Reuse activities not presently desig-

nated in the Wastewater Reclamation Criteria are subsequently

considered and evaluated on an individual case basis . )

The health hazards associated with wastewater reclamation are

directly related to the degree of public contact with reclaimed

wastewater and inversely related to the level of treatment pro-

vided for the wastewater . Where there is significant potential

human contact with reclaimed wastewater , extensive treatment must

be provided to produce reclaimed wastewater of adequate quality

for the intended reuse purpose . Table II summarizes the study

findings on the degree of treatment provided for the various

beneficial uses of reclaimed wastewater . The required treatmen t

BNA08657060

HDMSpO1750138

Wastewater Reclamation Facilities Survey -p6-( continued)

processes for each type of use are also indicated in the Table .For

example , reclaimed wastewater supplied to non-restricted recrea-

tional impoundments must be adequately disinfected , oxidized,

coagulated , clarified and filtered . This same treatment require-

ment also applies to reclaimed wastewater used both for spray ir-

rigation of non- processed food crops ( crops that are sold direct-

ly to consumers without extensive physical or chemical process-

ing) and surface irrigation of non- processed food crops that come

in direct contact with the reclaimed wastewater . The

coagulation- clarification- filtration treatment process is not re-

quired for reclaimed wastewater used to surface irrigate food

crops that do not come in direct contact with the irrigation wa-

ter, or processed food crops that must undergo extensive commer-

cial , physical and chemical processing before sale . On the other

hand,d ue to the low potential of public contact with reclaimed

wastewater , only a primary wastewater effluent is acceptable for

irrigation of fodder , fiber, and seed crops , orchards or vine-

gard s .

Table II shows that all the wastewater reclamation plants were

in compliance with the established treatment requirments for

their intended uses of reclaimed wastewater . The treatment pro-

vided often exceeds that prescribed in the wastewater Reclamatio n

Criteria . This was particularly apparent at plants supplying ef-

fluent for the irrigation of fodder , fiber, or seed crops, and

orchards and vineyards ; only six of the 144 wastewater reclama-

tion plants provided primary treatment for the reclaimed wastewa-

ter . Table II reveals that 72% (176 out of 243) of the wastewa-

ter reclamation plants provided higher treatment than required .

Table II does not reflect the October 1978 revisions to the

Wastewater Reclamation Criteria increasing the treatment require-

ment for landscape irrig ation of parks , playgrounds , and school-

yards or similar intensively used areas with unrestricted access,

at which the public may have intimate contact with the the irri-

gated areas . Reclaimed wastewater used in such areas must be

coagulated , clarified , filtered , and adequately disinfected to

provide reasonable assurance that effluents applied at these in-

tensively used areas are essentially virus free .

Although there are no statewide standards governing the quality

of reclaimed wastewater used for industrial uses , construction,

wildlife habitat enchancement , and aquaculture , the effluent

delivered to these users received a minimum of secondary treat-

ment with disinfection at all of the sites surveyed . The treat-

ment provided for these operations was found to be adequate for

public health protection .

2 . Treatment Reliability Provision s

Wastewater treatment plants should provide reliable , consistent

and adequate treatment for the reclaimed wastewater . The treat-

ment reliabilty requirements prescribed in the Wastewater Recla-

maton Criteria aim to provide assurance of consistent quality of

reclaimed wastewater delivered to the use areas . The minimum re-

liability provisions specified in the criteria include : ( 1) Alarm

systems ,(2) Standby power supply , ( 3) Treatment process reliabil-

ity (4) Emergency storage and disposal facilities , and (5 ) Flexi-

bility in piping system for emergency diversion of inadequately

treated effluent . This section discusses reliability provisions

required in all treatment processes except disinfection , which is

covered separately in Section 111-3 .

a . Alarm System s

An adequate alarm system is required in reclamation plants to

provide warning of loss of power and failure of all critical

treatment processes necessary to comply with the Wastewater Rec-

lamation Criteria . The alarm system should consist of visual

and/or audible signals to warn personnel of undesirable plant

conditions . The Wastewater Reclamation Criteria also require that

this system be independent of the normal power supply . In cases

where the reclamation plant is not attended full-time , the cri-

teria require that necessary alarm arrangements be made with oth-

er full - time service units, such as fire or police departments .

Of the 213 (97%) wastewater reclamation plants with completed

questionnaires , 11 (5%) had full-time ( 24 hour continuous ) atten-

dance . Twenty-two (11 %) of the remaining 202 wastewater reclama-

tion plants reported that alarm arrangement had been made with .

the fire or police department . Forty-nine ( 23%) wastewater rec-

lamation plants provided only a partial alarm system for their

required treatment unit processes . Of these 49 : ( a) Thirty-six

had all the required alarms, but the alarms were connected to

the normal power supply ; in which case these devices would be

rendered inoperable during power failures . ( b) Ten employed a

separate power supply only for the alarm signalling loss of the

normal power supply . In this case , this alarm alone should sig-

nal both the loss of normal power and problems with other plant

operations relying on electric power . ( c) The remaining three

did not have alarms for one or more of the required treatment

processes . Forty-six (22%) of the 213 wastewater reclamation

plants reported in the survey provided an adequate alarm system

as prescribed by the Wastewater Reclamation Criteria for their

plant operation .

b . Power Suppl y

The operation of most wastewater treatment processes depends, in

part , on electric power . During a power loss , these processes

would not operate properly ; for example , biological treatment

processes can be sigificantly impaired by outages lasting longer

than an hour . The Wastewater Reclamation Criteria state that a

standby power source should be provided at all reclamation plant s

BNA08657066

HDMSp01750144


except those which operate entirely by gravity .

Standby power sources observed in this survey included gasoline

and diesel operated generators and connections to other separate

power supply sources . Ten ( 5%) of the 213 wastewater reclamation

plants reported power failure occurrences in 1977 . In none of

these cases was a standby power source available . Normal treat-

1

1

ment processes were interrupted from 2 hours to 8 days . A stand-

by power supply was provided in 83 (39%) of the 213 wastewater

reclamation plants surveyed in this study . The majority (48 -

58%) of the wastewater reclamation plants providing standby power

utilized fuel-driven generators that required manual starting .

Only 35 (42%) of these facilities reported to have automatically

actuated, battery operated switchover devices on their standby I

power generators . Most of the plants perodically tested their

standby power generators to ensure proper operation of the equip-

ment .

c . Emergency Storage or Disposa l

The emergency storage or disposal provision is a basic reliabili-

ty feature for reclamation operations . The Wastewater Reclama-

tion Criteria require that these facilities be provided for the

temporary containment or disposal of inadequately treated waste-

water . Emergency storage refers to storage facilities other than

the normal storage which may be provided for reclaimed wastewater

until it is needed for use . Two types of emergency storage or

disposal provision are commonly employed in wastewater reclama-

tion plants : Short- term ( greater than 24 hour retention capacity)

and long-term ( greater than 20 days retention capacity) . One

hundred forty-two (67 %) wastewater reclamation plants provided

some form of emergency storage or disposal facilities including

holding ponds, storage tanks , diversion of the inadequately

treated flow to lower order uses or other designated disposal

areas ( e .g . percolation beds , sewer , other wastewater reclamation

plants for treatment , etc .) Automatically actuated emergency

storage or disposal facilities were provided at 27 wastewater

reclamation plants . The other 115 plants must divert the flow

manually to the designated areas . Ninty-one ( 64%) of the 142

wastewater reclamation plants equipped with this reliability pro-

vision reported to have used the emergency facilities at least

once during the year 1977 .

d . Alternative Reliability Requirement s

The criteria specify several alternative reliability requirements

for each of the treatment unit processes in the wastewater recla-

mation plants . When an automatically actuated long - term emergen-

cy storage or disposal facility is not available , a wastewater

reclamation plant should be equipped with an adequate alarm sys-

tem to indicate any undesirable conditions or breakdowns in the

treatment units . Additionally , the plant should have multiple or

standby treatment units which are capable of treating the entire

flow when the normal unit is inoperable . Another alternative is

to provide an alarm system which signifies problems in the plant

operation , a short-term emergency storage or disposal facility to

BNA0865706 8

HDMSp01750146


retain the wastewater flow temporarily , and standby replacement

equipment to service or repair the broken parts or units . A

long-term storage or disposal facility coupled with an adequate

alarm system is another alternative to meet the reliability re-

quirement for wastewater reclamation plants .

Determination of the unit processes deemed necessary to have re-

liability provisions was based on the required quality of the re-

claimed wastewater for the intended use purpose . For example,

many wastewater reclamation plants provided secondary treatment

for wastewater use for purposes that only require a primary ef-

fluent, consequently the unit process evaluated for reliability

provisions was the primary treatment unit process only .

Reliability problems encountered in the survey included 35 cases

of equipment outages reported from 31 wastewater reclamation

plants . They included power and pump failures,flooding(due to in-

sufficient storage capacity), or other mechanical breakdowns .

Nineteen wastewater reclamation plants reported to have delivered

inadequately treated effluent to use areas at least once in 1977 .

One hundred thirteen (53%) of the 213 wastewater reclamation

plants surveyed did not have adequate treatment reliability for

the necessary processes (excluding disinfection) . Table III sum-

marizes the findings on treatment reliability of the 213 wastewa-

ter reclamation plants investigated in this survey .

*Total number of wastewater reclamation plants with completedsurvey questionnaire equals 213 .

3 . Disinfection

Disinfection is the final stage of pathogen destruction in the

treatment process to produce a safe wastewater effluent for

reuse . For uses where public contact with reclaimed wastewater is

likely, provisions for adequate and reliable disinfection are the

most essential features of the reclamation process . To ensure

adequate disinfection , the State Department of Health Services

has established disinfection reliability standards for the waste-

water reclamation plants and bacteriological requirements for re-

claimed wastewater applied to use areas . Coliform analysis on

reclaimed wastewater must be performed on each day during which

the reclaimed wastewater is utilized .

BNA08657070

a . Disinfection Reliability Provisions

1

D

The Wastewater Reclamaton Criteria specify that the disinfection

process should be provided with the following features for unin-

terrupted chlorine feed :

(1) Standby chlorine supply ,

(2) Manifold system to connect chlorine cylinders,

(3) Chlorine scales, and

(4) Automatic devices for switching from empty to full

chlorine cylinders .

In addition, the disinfection unit process must be provided with

one of the following alternatives :

(1) Alarm and standby chlorinator ;

(2) Alarm, short-term retention or disposal provisions ,

and standby replacement equipment ;

(3) Alarm and long-term storage or disposal provisions ;

(4) Automatically actuated long-term storage o r

disposal provisions ; o r

(5) Alarm and multiple point chlorination, each with

independent power source , separate chlorinator,

and separate chlorine supply .

Of the eighty-two wastewater reclamation plants required to

disinfect their effluents for reclamtion, only 6 (7%) met the

above reliability standards .

visions of the 82 wastewater reclamation plants where disinfec-

tion is required for the production of reclaimed wastewater .

b . Coliform Analysis Frequenc y

The Wastewater Reclamation Criteria specify that coliform

analysis be performed on the reclaimed wastewater daily . The

survey did not determine which plants sampled for coliform organ-

isms only on days that the effluent was reclaimed . Therefore,

some of the facilities not taking daily samples might be in com-

pliance with the coliform sampling requirement by collecting sam--

pies only on days when reclaimed wastewater was transported t o

the use areas . 1

c . Bacteriological Compliance

Seventh- four of the 82 plants had bacteriological requirements

for reclamation purposes established by the Regional Water Quali-

ty Control Boards . Thirty-Five ( 47%) of the 74 wastewater recla-

mation plants reported to have exceeded their bacteriological re-

quirement at least once in 1977 .

4 . Use Area Operation s

With few exceptions , reuse practices must be effectively con-

trolled to minimize public and worker contact with reclaimed

wastewater at.the use areas . The State Department of Health Ser-

vices has developed use area control guidelines to minimize

health risks ( 2) . These guidelines state, for example, that the

discharge of reclaimed wastewater should be confined to the area

designated and approved for reuse , and that maximum attainable

separation of reclaimed wastewater lines and domestic water lines

should be practiced . The use area facilities must comply with

the 'Regulations Relating to Cross -Connections', Title 17,

Chapter V , Sections 7583-7622 , inclusive , California Administra.-

tive Code ( 3) . All reclaimed wastewater valves and outlets should

be appropriately tagged to warn public and employees that the wa-

ter is not safe for drinking , and all reclaimed wastewater valves,

outlets and sprinkler heads should be of a type that can only be

operated by authorized personnel . Adequate means of public no-

tification should be provided to indicate the use of reclaimed

wastewater . Such notificaton should include the posting of con-

spicuous warning signs with proper wording of sufficient size to

be clearly read .

Reclaimed wastewater used for irrigation should be confined and

controlled to minimize ponding . Runoff or tailwater should be

contained and properly disposed . For landscape irrigation opera-

tions , off-hour irrigation should be practiced to minimize the

potential of public contact with reclaimed wastewater .

Sprinklers should be properly installed so as to avoid aerosols .

In cases such as fodder, fiber , and seed crops irrigation using a

low quality reclaimed wastewater , the public must be effectively

excluded from contact with the reclaimed wastewater by means of

fences, signs , and key-operated valves and outlets . Furthermore,

animals should not be allowed to graze on reclaimed wastewater

irrigated lands until it is thoroughly dry . For food crop irri-

BNA08657074

HDMSp01750152


gation operations , adequate time should be provided between the

last irrigation and harvesting to allow the crops and soil to

dry . Surface irrigated food crops should not be allowed to come

into direct contact with reclaimed wastewater .

Reclaimed wastewater used for impoundments should be properly

contained and runoff properly disposed . At restricted recrea-

tional and landscape impoundments , all valves and outlets should

be appropriately tagged to warn the public that the water is not

safe for drinking or bathing . Adequate measures should be taken

to prevent body contact activities at these use areas . Restrict-

ed and nonrestricted recreational impoundments should be main-

tained under the continuous supervision of qualified personnel

during periods of use .

Worker protection is an essential integral part of wastewater

reuse control practices . Employees who may come in contact with

the reclaimed wastewater must be fully aware of the potential

health hazards involved and not become complacent regarding safe-

ty procedures . Before workers are allowed to work in the vicini-

ty of reclaimed wastewater , they should be instructed about the

potential of disease transmission and the precautions they should

take . Field workers should have periodic medical examination and

immunizations against tetanus and typhoid . Good personal hygiene

should be practiced to minimize exposure to reclaimed wastewater .

Skin contact with reclaimed wastewater can result in dermatitis

and other skin diseases . Open wounds are especially susceptible

1

1

i

BNA08657075

HDMSp01750153


to infection by pathogenic agents since they present a ready mode

of entry into the body . Washing facilities and a safe supply of

drinking water should be provided at the use areas . Hand washing

facilities reduce the possibility of disease transmission by

hand-to- mouth contact . Providing a safe drinking water supply

will reduce the chances of an employee either negligently or

deliberately drinking reclaimed wastewater . Employee contact

with reclaimed wastewater can also be diminished by wearing pro-

tective clothing , posting warning signs, and color - coding or tag-

ging all piping , valves and outlets to differentiate reclaimed

wastewater from domestic or other water .

a . Crop Irrigatio n

Crop irrigation constitutes the major use of reclaimed wastewater

in California . In 1977, over 20,000 acres of agricultural lands

were irrigated by 117,319 acre - feet of reclaimed wastewater( 64%

of total reclaimed wastewater used ) . Eighty-nine percent

(104,279 acre- feet ) of the reclaimed wastewater used for agricul-

tural irrigation was for the production of fodder , fiber and seed

crops, consisting mainly of alfalfa , barley, cotton , silage corn,

hay, and oats . Twenty-one orchard and vineyard irrigaton opera-

tions ultilized approximately 7% (8,066 acre -feet) of the total

agricultural use of reclaimed wastewater . Food crops such as

sugar beets , pumpkins, corn , bell peppers , tomatoes , beans, garl-

ic, garbonzos , and chili peppers accounted for the remaining

agricultural reclamation activities ( 4,974 acre-feet - 4%)-

Food Crops :

/

This survey determined that eight wastewater reclamation plants

supplied reclaimed wastewater for food crop irrigator . Seven

plants provided oxidized, disinfected effluent to the use areas. 4

The City of Livermore Wastewater Reclamation Plant provided addi-

tional in-line coagulation-filtration treatment to the effluent

used for sugar beet irrigation . Two use areas provided additional 1

storage and one blended the reclaimed wastewater with well wate r

prior to distribution in the field . Surface and/or drip irriga-

tion were employed in all eight operations . Spray irrigation was /

used to pre-irrigate crops before germination in three of the us e

areas . All of the eight food crop operations included in this

survey produced processed food crops which undergo extensive phy-

sical or chemical processing prior to sale .

Although all farmers interviewed were generally aware of the use 1

of reclaimed wastewater , they appeared to be more concerned abou t

the economic value of their crops than the public health aspect s

of reclaimed wastewater . No adverse effects on crops irrigated 1

with reclaimed wastewater were reported . None of the field work-

ers reportedly received immunizations against tetanus and tyhpoid

or periodic medical examinations . The use areas were regularly

inspected by the public health and State Department of Agricul-

ture agencies .

Results of field observations on reuse practices at these use

areas include : ( 1) Fences were installed at two of the eight use

areas surveyed . ( 2) No warning signs were posted anywhere in the

fields. ( 3) Only one reuse site had drinking water facilities

installed for field workers ; others must have bottled water car-

ried out to the fields . Occurrences of field workers drinking

reclaimed wastewater were reported in two of the reuse sites .

Food crop users generally realized the economic importance of

having an adequate and reliable source of water supply to irri-

gate the crops . Four ( 50%) users had legal contracts with the

reclaimed wastewater suppliers . An alternate source of water was

available in five of the use areas to augment the reclaimed

wastewater supply . Four indicated that they could completely re-

place the reclaimed wastewater supply by another source .

Fodder,Fiber,and Seed Crops,Orchards and Vineyards :

One hundred ninety fodder ,fiber,or seed crops and 21 orchard

and/or vineyard irrigation use areas were documented . Although

these types of reuse operations require only a primary treated

effluent , 138 (96 %) of the 144 wastewater reclamation plants sup-

plied effluent of higher quality to the use areas . Spray irriga-

tion was utilized in 70 ( 33%) of the use areas . Surface irriga-

tion was used in the remaining 141 (678) . Sixty-eight of the

reusers had legal contracts with the reclaimed wastewater sup-

pliers and 40 .intended to increase the use of reclaimed wastewa-

ter in the future .

b . Groundwater Recharge

4

1Included in this survey were five groundwater recharge operations

which reclaimed 25,981 acre - feet or 14 . 2% of the total reclaimed

wastewater used in 1977 . These operations served two main pur-

poses : (1) To replenish the groundwater supply ( three opera-

tions ) ; and (2 ) To prevent salt-water intrusion into groundwater

aquifers ( two operations ) . Incidental groundwater recharge ac-

tivities such as percolation from rivers or streams into which

wastewater effluents are discharged , or infiltration from spread-

ing beds where wastewater is disposed , are not considered as

planned reclamation operations and consequently not included in

this survey .

The Orange County Water District and Santa Clara Valley Water

District have direct injection- extraction operations intended to

prevent saltwater intrusion in coastal areas by creating a hy-

draulic barrier . The recharged water is subsequently withdrawn

from extraction wells located inland from the injection wells to

prevent contamination of usable aquifers by the reclaimed waste-

water . These two operations provide tertiary treatment ( coagula-

ton , clarificaton and filtraton ) for the wastewater effluents

injected into the groundwater aquifers . The Orange County Water

District , in addition , provides reverse osmosis treatment to ap-

proximately 30% of the reclaimed wastewater produced in the

plant .

The remaining three groundwater recharge facilities utilize

spreading and percolation to replenish the groundwater supplies .

The San Jose Creek and Whittier Narrows Wastewater Reclamation

Plants have recently upgraded their secondary treatment scheme to

include in- line filtration . Both of these two plants supply re-

claimed wastewater to the San Gabriel River Spreading Basin . The

Rio Hondo Basin is supplied solely by the Whittier Narrows Waste-

water Reclamation Plant . Chino Basin Municipal Water District

Regional plant t1 provides undisinfected oxidized effluent blend-

ed with approximately 758 surface water to recharge the Ely

Basin . The areas of surface spreading beds are ten acres (Ely

Basin), 260 acres ( San Gabriel River Spreading Basin ), and 570

acres (Rio Hondo Basin ) . The relamation season occurs during the

dry months ( May-November ) of the year for these three spreading

operations .

In 1977, 13,407 acre - feet ( 52% of total relaimed wastewater used

for recharge ) was supplied by the San Jose Creek Wastewater Rec-

lamation Plant ; Whittier Narrows Wastewater Reclamation Plant ac-

counted for 7,040 acre- feet ( 278) and Water Factory 21 of the

Orange County Water District supplied 5,204 acre-feet ( 20%) for

recharge . The balance (330 acre -- feet - 18) was accounted for by

the Santa Clara Valley Water District and Chino Basin MWD Region-

al Plant #1 . The percentage of reclaimed wastewater in the re-

charge stream ranged from 38 to 508 . Dilution waters used for

blending include surface runoff , well water and Colorado River

water .

All groundwater recharge operations had provisions to exclude

BNA0865708 0

HDMSp01750158


public from use areas . Fences were installed at the three spread-

ing operations, and warning signs were posted at two of the

operations . The Rio Hondo-San Gabriel River channel spreading

grounds were patrolled daily to prevent trespassing , while the

direct injection operations had injection and extraction wells

installed in enclosed structures which were attended by and ac-

cessible to authorized personnel only .

All the groundwater recharge use areas were well maintained and

regulated . Periodic medical examinations were compulsory at two

of the use areas . Results of the quality analysis of the re-

claimed wastewater were supplied by reclamation plants and sent

to all five recharge agencies . The reclaimed wastewater was also

extensively monitored by the agencies .

Two recharge agencies have legal contracts with the reclaime d

wastewater suppliers for the adequate delivery of reclaimed

wastewater . Increased recharge was expected at all five of the

operations . Two operations indicated that they had alternate wa-

ter sources to augment and/or replace the reclaimed wastewate r

supplies , if necessary .

c . Landscape Irrigatio n

Landscape irrigation accounted for 23 ,908 acre-feet or 13% of th e

total reclaimed wastewater used in 1977 . The 104 landscape ir-

rigation operations consisted of 43 golf courses , 16 freeway

landscapes and city medians , 16 nurseries (shrubberies, trees,

and turf areas , etc .), 13 parks , 10 schoolyards , 4 playgrounds,

and 2 cemeteries .

Golf Courses , Cemeteries , Freeway Landscapes , and Nurseries

Fifty- six wastewater reclamation plants supplied at least a

disinfected, oxidized effluent to the 77 use area operations on

golf courses, cemeteries, freeway landscapes, and nurseries . Re-

claimed wastewater was transported to these use areas by pressure

or gravity pipeline except in a few freeway landscape and city

median areas , where trucks were used . At golf courses, reclaimed

wastewater was usually piped to holding ponds on the course,

where it was then pumped through the distribution sprinkler sys-

tems . In addition to providing storage for reclaimed wastewater,

these holding ponds served as water hazards for the golfers . The

water hazards were, in most cases, adequately maintained and

odorless but heavy with algal growth . A few reusers reported that

algae and other solids present in the reclaimed wastewater con-

tributed to sprinkler clogging (7 cases) and pump plugging (4

cases ) . Microstrainers were installed to mitigate these problems

in four use areas . Other additional treatment applied to re-

claimed wastewater at the use areas included blending with well

or domestic water, and chlorination . High salt levels, especial-

ly sodium, was another common complaint from groundskeepers .

(High sodium can cause infiltration problems or blockage of soil

which consequently causes the withering of affected vegetation) .

Landscape irrigation areas at golf courses, nurseries and freeway

landscapes ranged in size from 20 to 200 acres . Water usage s

BNA08657082

HDMSp01750160


varied widely . The annual reclaimed wastewater flow ranged fro m

seven to 1,600 acre-feet for a single use area . I

The majority , 55 (71 %) of these reusers , employed pressure-

operated pop-up sprinkler heads having covers that are flush with

the ground surface when not in use . The hydraulically actuated

sprinkler head readily lends itself to automatic operation . Au-

tomatic operation , in turn, reduces the potential for employee

contact with reclaimed wastewater . Fifty-five (718) of the ir-

rigation operations were controlled by automatic timing devices .

Ten (13% ) employed quick -coupling type sprinklers , and seven (98)

utilized the rotary shot-gun type sprinklers . Drip irrigation

was employed in two ( 38) operations for watering trees, while

three ( 4%) used a combination of pop-up and quick-coupling sprin-

kling system . Quick-couplers are operated in conjunction with

above-ground sprinkler heads or hoses for mobility . Because a

manual coupling connection is required to actuate these

sprinklers , the potential for employee contact with reclaimed

wastewater is increased , which accentuates the need for employee

awareness and protection . Manual operation was employed in 20

(268) of the use areas . There were eight ( 10%) trucking opera-

tions which supplied reclaimed wastewater to freeway landscape

and city median strip irrigation sites . These reclamation opera-

tions were at all times under close supervision of trained and

authorized personnel .

Personnel at the use areas indicated they were aware of the

safe, beneficial use, and health implications of reclaimed waste-

water . Operators were required to undertake training courses in

reclaimed wastewater application at five ( 7%) of the reuse facil-

ities . Ten ( 138) of the operations reported that their personnel

were subjected to periodic medical examination and immunization

against tetanus and typhoid . Routine inspections by public

health and other agencies were reportedly performed at 33 (438)

of the 77 use areas .

Reusers in this category provided good public notification on the

reclamation activity . Adequate public warning was provided at 64

(838) of the use areas . Warning signs were posted at the en-

trances , on the fences , and in the water hazards . Four ( 5%) golf

courses had a warning notice printed on the scorecards. Trucks

used to transport reclaimed wastewater were posted with signs to

warn people that they contained reclaimed wastewater . Freeway

landscape , and city median strip areas were not posted with any

type of warning signs at all .

Some common deficiencies noted at these use areas were : (1)

Thirty-one ( 40%) of the operations did not irrigate during off-

hours ; ( 2) Water ponding was noted at 11 ( 148) use areas during

the survey; ( 3) Public pathways wetted by reclaimed wastewater

were observed at 15 ( 20%) of the reuse sites ; (4) Two incidences

of golfers being sprayed with reclaimed wastewater were observed ;

(5) Windblown spray was noted at 13 (17%) of the golf courses,

and they were situated within close proximity of homes ; and (6)

The lack of protection of drinking water fountains against spra y

BNA08657084

HDMSp01750162


was apparent . Sixty-one (79 %) provided drinking water fountains

but only 11 (18%) of which were adequately protected from re-

claimed wastewater contamination . Drinking water fountains were

observed being sprayed with reclaimed wastewater at three (5%)

use areas . Public drinking from unattended reclaimed wastewater

sprinkler heads were reported at five use areas .

•

•

•

Twenty-three ( 30%) of the 77 reusers had legal contracts with the

reclaimed wastewater suppliers to insure adequate delivery (quan-

tity and/ or quality ) of reclaimed wastewater to these areas .

Forty-seven ( 61%) operations had another water source to augment

their reclaimed wastewater supply in case of shortage . Of these

47, 42 ( 90%) could completely replace their reclaimed wastewater

supply with other sources of water . The rest of the operations

were entirely dependent on reclaimed wastewater . Sixteen (21%)

use area operations expected an increase in reclaimed wastewater

use while only 3 ( 4%) indicated that they would reduce the use of

reclaimed wastewater .

Parks , Schoolyards, and Playgrounds :

This survey included landscape irrigation at 27 parks, play-

grounds, and schoolyards . Reclaimed wastewater was transported

from the wastewater reclamation plants directly to the use areas

by pressure or gravity pipeline in all cases except one, which

trucked the water to the reuse site . of the 24 wastewater recla-

mation plants that supplied reclaimed wastewater to these use

'areas , 13 (54 %) provided secondary treatment and disinfection,

1

BNA08657085

HDMSp01750163


seven ( 21%) provided secondary treatment , filtration , and disin-

fection, and 4 (17%) provided secondary treatment , coagulation,

filtration and disinfection for the reclaimed wastewater . (It

should be noted that due to the highly varying degree and poten-

tial of public contact with the reclaimed wastewater used at

parks , playgrounds , and schoolyards , the treatment requirement

for the effluent has been recently revised to include coagula-

tion , clarification and filtration ; the bacteriological quality

of the reclaimed wastewater must meet a seven day median value of

2 .2 MPN coliform and a maximum value of 23 MPN coliform .) Three

users (11%) employed microscreens and one user ( 4%) stored the

reclaimed wastewater at the reuse sites in ponds prior to use .

Adverse effects reported included odor and poor percolation .

All except the trucking operation employed spray irrigation .

Twenty-one ( 78%) operations used the pressure actuated pop-up

sprinkler systems, four ( 15%) used the rotary shot -gun and one

(4%) used the quick -coupling type sprinkler systems . Automatic

irrigation control was employed at 16 ( 59%) of the use areas .

Generaly , use area controls were poor at these reuse operations .

Ponding was observed in nine ( 33%) of the use areas . Reclaimed

wastewater entering public pathways such as public roads, parked

cars, picnic tables,etc ., was observed in 12 ( 44%) use areas .

Windblown spray was observed at two ( 7%) use areas . Sixteen (59%)

irrigated during off-hours . Eleven ( 41%) areas were irrigating

with reclaimed wastewater during the time of field investigation .

Seventeen users ( 63%) had drinking water facilities at the sites ;

BNA0865708 6

HDMSpO1750164


only 4 (24%) protected water fountains from reclaimed wastewater

spray . Seven instances of either the public or employees drink-

ing reclaimed wastewater were reported in this survey . Ten (37%)

use areas reported that they were regularly inspected by public

health or other agencies .

Personnel were generally informed of the use of reclaimed waste-

water , but were not fully aware of, or concerned about, the

health implications . None of the users received results of re-

claimed wastewater quality analyses . Of the 27 use areas, only

three ( 11%) required regular medical check -up and immunizations

against typhoid and tetanus for their employees . Ten (37%) were

posted with some form of warning signs on fences , faucets, pipes,

fire hydrants and entrance to the use areas . Inadequate warnings

were particularly apparent at schoolyards and playgrounds where

the users were generally unaware of the application of reclaimed

wastewater or its health implications .

Seven (26%) use areas had a legal contracts for the reclaimed

wastewater supply . Fourteen ( 52%) areas had an alternate source

to augment their reclaimed wastewater supply while 11 (41%) could

replace their supply entirely by another source . Sixteen (59%)

of the 27 were totally dependent on reclaimed wastewater for ir-

rigation of their landscape areas . Four ( 15%) users indicated

increased reclaimed wastewater use and only one (4%) expected a

decline in future use .

d . Impoundment s

Thirteen impoundments utilizing 6,891 acre - feet of reclaimed

wastewater , accounted for approximately 38% of total reclaimed

wastewater used in 1977 . There were six landscape ( ornamental)

impoundments , six restricted recreational impoundments (where

fishing, boating , and/or hunting activities are permitted), and

one was a nonrestricted recreational impoundment ( where body-

contact sports are permitted) . Each of the three types of im-

poundment was responsible for a third of the total reclaimed

wastewater used for this type of reclamation .

South Tahoe PUD, suppling the only nonrestricted recreational

impoundment ( Indian Creek Reservoir ), provided coagulated , clari-

fied, filtered and carbon - treated effluent to the reservoir .

All other impoundments received at the minimum oxidized and

disinfected effluent . Four users blended the reclaimed wastewater

with well or domestic water .

All impoundments except the Santee Reclamation System were sup-

plied with reclaimed wastewater transported directly by pipeline

from the wastewater reclamation plants . At Santee, oxidized,

disinfected wastewater effluent was percolated in 11 percolation

beds through 400 feet of soil , then collected in a common chan-

nel . From there the water flowed by gravity to the Santee Lakes,

the restricted recreational impoundment in which non - body contact

sports are allowed .

Common deficiencies noted in these use areas include the follow-

BNA0865708 8

HDMSpO1750166


ing : The majority of the impoundments abounded with alga l

growth ; foaming was a common nuisance noted in many impound- 4

ments ; adequate drinking water facilities were not provided a t

six (46% ) facilities ; people drinking reclaimed wastewater wer e

noted at three ( 23%) reuse sites . Warning signs were not posted 4

at 9 (69 %) of the use areas .

Personnel at four ( 31%) of the reuse sites indicated that they

received periodic medical examination and/or immunization shots,

which were mandatory at only two ( 15%) of the use areas . Six

(46%) of these use areas were reportedly inspected periodicaly by

public health or other agencies .

4

I

Two (15% ) of the impoundments had legal contracts with the waste-

water reclamaton plants for reclaimed wastewater supply . In- 4

creased reclaimed wastewater use was anticipated in three (23% )

of the use areas . Seven ( 54%) of those sites had an alternate wa-

ter source to augment and/or completely replace the reclaimed 4

wastewater supply to the impoundments in case of reclaimed waste-

water shortage .

e . Industrial Uses

Eight industrial reuse operations accounted for 8,613 acre-feet

(5%) of total reclaimed wastewater used in 1977 . The operations

consisted of five industrial cooling water uses , two veneer

plants for log decking spraying and one cement slurry operation .

Six (75%) of these plants received oxidized , disinfected effluent

and two ( 25%) received oxidized , filtered and disinfected waste-

water effluent . Additional treatment 'such as ponding, chlorina-

tion , pH control and/or phosphate removal were provided at three

( 38%) of the reuse sites .

Operational problems associated with reclaimed wastewater were

reported to be scaling in heat exchangers, and fouling and cor-

rosion in cooling towers and reclaimed wastewater lines .

Industrial users generally appeared to be more aware of the

health aspects of reclaimed wastewater . Concern for worker pro-

tection was greater than for most of other types of reuse sur-

veyed . Three ( 38%) users periodically received results of quality

analyses done on the reclaimed wastewater . Personnel were ad-

vised of the use and health implications of reclaimed wastewater

as part of their training program . Periodic employee medical ex-

aminations were mandatory at one ( 13%) of the use areas and

recommended at two (25%) of the others . Four ( 50%) of the eight

operations had piping and valves that were either tagged, la-

belled , or color-coded to distinguish reclaimed wastewater lines

from other pipes . Proper cross-connection measures were taken at

all the reuse operations . Warning signs were provided at one

(13%) of the operations . The use areas , in general , are not ac-

cessible to the public . Routine inspections by public health or

other agencies were performed in 4 (50 %) of the use areas .

Six users (75%) indicated that they had an alternate water source

to augment or completely replace the reclaimed wastewater supply

if necessary . An increase in reclaimed wastewater use was anti-

BNA08657090

HDMSp01750168


cipated at one (13 %) reuse operation . Only one operation had con-

tracted for the reclaimed wastewater supply . Rocketdyne Division

of Rockwell International and Kaiser Steel operate their own

wastewater reclamation plants, thereby negating the need for le-

gal contract for reclaimed wastewater supplies .

f . Construction and Dust Control

This survey included 12 uses of reclaimed wastewater for con-

struction and dust control which constituted approximately 0 .1%

of the total reclaimed wastewater used . These operations used

reclaimed wastewater for concrete slurry mixing , wash down and

dust control at construction sites and sanitary landfill areas .

Ten (83 %) of these operations trucked reclaimed wastewater to the

reuse sites . The trucks were adequately labelled with warning

notices . Cross- connecton prevention devices were installed in

all of these trucks . The application of reclaimed wastewater at

all times was under the control and supervision of trained and

authorized personnel . None of the operations mandated periodic

medical examination or immunization shots for the employees .

Only three ( 25%) of the use areas were routinely inspected by

public health agencies .

Three ( 25%) reported that they had an alternate source to augment

and/or completely replace the reclaimed wastewater source . Three

(25%) projects anticipated more use in the future . There were no

legal contracts for reclaimed wastewater supplies for any of the

reusers .

INTENT OF REGULATIONS

The intent of these regulations is to establish acceptable levels of con-stituents of reclaimed water and to prescribe means for assurance of relia-bility in the production of reclaimed water in order to ensure that the useof reclaimed water for the specified purposes does not impose undue risksto health. The levels of constituents in combination with the means forassurance of reliability constitute reclamation criteria as defined in Se c.-tion 13520 of the California Water Code .

As affirmed in Sections 13510 to 13512 of the California Water ( :urlr%water reclamation is in the best public interest and the policy of the Stateis to encourage reclamation . The reclamation criteria are intended topromote development of facilities which will assist in meeting water re-quirements of the State while assu ring positive health protection . Appro-priate surveillance and control of treatment facilities , distribution systems,and use areas must be provided in order to avoid health hazards . Precau-tions must be taken to avoid direct public contact with reclaimed waterswhich do not meet the standards specified in Article 5 for nonres ! rictedrecreational impoundments .

7616 . Fire System. Water systems for fighting fire, derived froma supply that cannot be approved as safe or potable for human use shall,wherever practicable, be kept wholly separate from drinking water pipe-lines and equipment . In cases where the domestic water system is usedfor both drinking and fire fighting purposes, approved backflow preven-tion devices shall be installed to protect such individual drinking waterlines as are not used for fire fighting purposes . It is hereby declared thatit is the responsibility of the person or person, eaucimt the intrrniuctionof said unapproved or unsafe water into the pipt•lint-s to .oe : (1) that aprocedure be developed and carried out to notify and protect users ofthis piping system during the emergency ; (2) that special precautionsbe taken to disinfect thoroughly and hush alit all pipelines which mayhave become contaminated before they are again used to furnish drink-ing water. In the event the means of protection of water consumers isby disinfection of the auxiliary fire fighting supply, the installation andits use shall be thoroughly reliable .

When disinfection of the auxiliary supply itself is depended uponto render the water safe, the means of applying the disint'ectant underthis regulation shall be automatic with operation of the pinup or pumpsemployed with the dangerous water in question . Adequate supplies orehlrn•ine or its compounds must be kept on hand at ill times . Chlorinedosing, equipment shall be tested daily and kept in good operating con-dition ,

The public water supply must be protected against backflow fromsuch dual domestic fire systems as detailed in Section 7604 .

7617 . Process Waters. Potable water pipelines connected toequipment for industrial processes or operations shall be disconnectedtherefrom if practicable . Where disconnection is not practicable, a suit-able baekflow prevention device located beyond the last point from whichdrinking water may be taken shall be provided on the. feed line to processpiping or equipment . In the event the particular process liquid is espe-cially corrosive or apt to prevent reliable action of the backflow preven-tion device, air-gap separation shall be provided. These devices shall betested by the water user at least once a year, or more often in thoseinstances where successive inspections indicate repeated failure . Thedevices shall be repaired, overhauled or replaced whenever they arefound to be defective. Records of tests, repairs, and replacement shallbe kept and made available to the local health department.

7615. Sewage Treatment Plants and Pumping Stations . Se►vagepumps shall not have priming connections directly off any drinkingwater systems . No connections shall exist between the drinking watersystem and any other piping, equipment, or tank in any sewage treat-ment plant or sewage pumping station .

7619. Plumbing Connections. Where the circumstances are suchthat there is special danger to health by the backflow of sewage, as fromsewers, toilets, hospital bedpans, and the like, into a drinking water

water supply piping which is too small , thereby causing vacuum condi-tions when fixtures are flushed or water is drawn from the system inother ways, it is recommended that water supply piping that is toosmall he enlarged whenever possible .

7620. Pier and Dock Hydrants. Packflow protection by a suit-able backllow prevention device shall hn provided on each drirtlcintg

water pier head outlet used for supplying vessels at pu•rs or water-fronts.
