Objective- Promote Healthy Living
• 1st Priority • Deliver Water to
Dorm
• 2nd Priority• Improve Hygiene
and Health of the Community
Trips To Gather Necessary InformationTrip 1: June 6- June 14,
2009Trip 2: Jan 26 – Feb 2, 2010• Needs of community• Sources of water• Elevations• GPS coordinates• Water quality• Flow rates of water
sources• Water rights• Ground conditions• Available building
materials and pricing
Water Supply
• River water
• Ground water
• Rainwater
• Spring water
• Bottled water
Where to get the water…
Water Supply
• Rainwater • Irrigation
• Spring water• Drinking• Hygiene
Concept Spring water
Rainwater
Water Supply Systems
Water Supply SystemGround Water Spring
• Spring Features• Marshy, unable
to locate eye• Clay soils• 98 m above
dorm• 1.4 km from
dorm• 2 L/min flow
rate• Community has
approved this spring for the dorm’s water supply
Marshy Area
Flow Direction
Spring Water to DormCapture water from a spring
• Design Features• Two 15’ trenches
filled with permeable rock/gravel and 3’ PVC drain tile
• Drainage ditch upstream of spring to stop runoff infiltration
• Cost = $140
Spring Water to Dorm
• Design Features• Concrete box
• 3’ x 3’ x 1’6”• 3” walls
• Concrete lid• 3’1” x 3’1” x
1.5”• Settles out
particles Ø > 0.001 cm
• Cost = $150
Settle particles out of water
Spring Water to Dorm
• Water Demand Estimate for Dorm• The maximum capacity is 40 kids• The kids stay for 4 day periods each week• The average demand for a week is 2,400 L/day
• Water Supply from Spring• Rough estimate is 2 L/min• This estimates to about 2,900 L/day
Analysis of Water Demand
Spring Water to Dorm
• Design Features• Positioned at an elevation
(95 ft above dorm) that gives at least 40 psi and a flow rate of 7 gal/min
• Ferrocement tank • Volume of 5,000 L (6.5’
diameter, 5.5’ tall)• Cost = $400
Storage Tank to EqualizePressure & Flow Variations
Water System at DormWater Purification
• Filtration• CAWST bio-sand
filter• Cost of mold = $185• Cost per filter (not
including mold) = $20
• Disinfection
• Granular calcium hypochlorite
• Cost per pound= $2.00
Water System at DormHot Water System
• Solar Heating Panel• Copper pipe• Glass covered• Circulating Pump• Heats 20 gal (75
L) of water to 95ºF inabout 5 hours
• Wood Fired Boiler• Recommended a
manufactured unit
Rainwater & IrrigationWater for Community Crops
• Gutters• 4 plastic storage
tanks(1000 Liters)
• Irrigation to community fruit trees and vegetables
• Cost = $930
Hygiene ImprovementsPit Toilets
• One pit toilet per family
• Lightweight superstructure
• Concrete block pit lining
• 3 meters deep by 1.3 meters square
• Cost per latrine = $240
Hygiene ImprovementsEducation
• CAWST posters
• Educate children about healthy sanitary practices
• Easy to understand
• Pictorial
• Spanish and English
ImplementationJune 2010
• Phase I• Cost = $1,500
• Phase II• Cost = $2,500
• Phase III• Cost = $6,000
Building the Filter MoldSteel. Welding. Steel.
• Over 150 lbs of steel from GR Central Iron and Steel
• Finished on April 27
• Cost = $185
• Issue: Took longer than expected
Filter #1Failure
• Poured filter on May 4
• Problem: Interior mold stuck in filter
• Solution: Break filter and retry!
Filter #2More success, still a failure
• Changes made• Homemade concrete
mix – as design specified
• Less water• Pneumatic hammer• Ground all rough
edges• Lathered on the oil
• Mold didn’t stick
• Crack from mid-pour mix change
ConclusionsFinal Thoughts
• Difficulties we faced• Data acquisition
• What we learned• More than engineering• Design to be built
• What we would have done differently• Built the prototypes earlier and
experimented more
• Plans are in the works to implement the project
