LOCALITY PLAN

INSTRUCTIONS ON USING THIS DESIGN TEMPLATE SHEET &EXAMPLE DESIGNS:A. Text in blue italics is instructional information for the designer to act

on.Once the action has been completed, the blue italics text should beremoved.

B. Non italics text colored black is part of the design template and shallremain in place if relevant.

C. Non italics text colored magenta is provided as an example only andshall be removed or modified to be specific to the design beingproduced.

D. The template & example design is split into 3 parts(MRWA-W-101,102 &102B)1.Part 1 (MRWA-W-101, this sheet) shall include all notes and a

locality plan. This part is a TEMPLATE which shall be filled in aspart of all water pipeline designs. Much of the notes text isprovided and will likely remain consistent across all jobs. All notesmust be confirmed by the designer and only included if relevant.Job specific requirements outside of those already quoted must beadded by the designer. The intent is that all of Part A fit on onesheet and be readable when printed on A3 paper.

2.Part 2 (refer to MRWA-W-101A which is an EXAMPLE thatdemonstrates the layout, line and text requirements) which is tocontain the design drawing(s) which shall take up the whole pageand have a maximum scale of 1:500 on A1 paper (equivalent to1:1000 on A3 paper, which is readable). There may be a numberof sheets to Part 2 depending on the size of the design).

3.Part 3 (refer to MRWA-W-101B which is an EXAMPLE thatdemonstrates the layout, line and text requirements) shall containall schematic enlargements (details) which show constructioncomponents and how they are to be configured. Schematicenlargements will be required when there are more than six (6)fittings in close proximity (ie: 5 meter diameter circle) or a nonstandard arrangement is proposed (this often occurs at valve andhydrant clusters).

E. All symbology used in Parts 2 & 3 must be as shown in standarddrawing MRWA-W-100.

F. MRWA-W-100 & 101 are available in CAD and MS Word format fromthe water agency for adjustment & issuing to contractors.

G. All works are to be designed in accordance with WSA 03- 2011MWRA edition.

H. Sewer designs shall not be included in DW & NDW designs.

the Australian Height Datum (AHD) are provided in thedesign drawings. (The designer shall mark all TBMs onplans)

8. All levels are in metres to AHD.9. All co-ordinates are in metres to the Map Grid of Australia

(MGA 55- 94).10. The Contractor is directly responsible for ensuring the project

set out is consistent with the design. Should actual siteconditions conflict in any way with that documented, theContractor shall contact the Superintendent for clarificationbefore proceeding.

11. The Contractor is to engage a suitably qualified andexperienced Surveyor to undertake asset recording of thework. All surveyor works and data recording shall beundertaken in accordance with the MRWA survey manual.

12. All specific pipe materials (eg: PVC-O) shall be indicated inthe As Constructed information

Products and Materials (Refer Table 1 & 2)(Consult with the Water Agency where test pressures exceed 1600kPa. Where a higher test P is accepted, provide instruction to theConstructor on the products and materials to be used)13. DW and NDW system components shall be differentiated as

per section 4.2 of WSA03-2011, MRWA edition. (Remove ifnot a Dual Water design)

Appurtenances (Fittings- Refer Table 3)14. (insert any relevant notes here)

Water Main Alignment, Trenching & Cover (Refer Table 5)15. Offsets of mains from property boundaries shall be; min

600mm (mains < DN100) and min 1m (mains > DN100).16. All water mains shall pass over drains and sewers unless

shown otherwise in the design drawings.(Designer is to ensure that wherever practical, water asset offsetscomply with those stated within the "Road Management Act 2004Code of Practice for Infrastructure in Road Reserves").

Embedment17. (Nominate acceptable embedment system(s) and nominate

where each is required.)

Backfill18. (Nominate the road owner's backfill material and compaction

requirements (ie: Vicroads or Council) for road reservebackfill.)

19. Non trafficable backfill shall be completed as perMRWA-W-201 and the current version of the MRWA BackfillSpecification.

Thrust Restraint (Refer Table 6)20. Thrust restraints have been designed on the basis of the

AHBP (ground strength) nominated in TABLE 6. TheContractor shall confirm the actual ground conditions anddiscuss with the Superintendent any ground conditions whichare found to be different to that nominated. (Designer toundertake a Geotechnical investigation and quote (in Table6) the AHBP of the ground used in calculating each thrustrestraints, especially for thrust restraints > 2m²)

Property Services21. NDW property services shall always be located on the left of

the DW property service as you look from the road to thefront of the property. (Remove if not a Dual Water design)

Connections (All types)22. All property service connections to new residential RRJ

reticulation mains are to be completed using pretappedconnectors.

Other Services (Ref- Table 5 & 7)23. To receive the most up to date information prior toconstruction, “Dial before you Dig” shall be undertaken to aidin the location of other services.Other services shall be carefully located prior to fullexcavation at the contractor's cost.Any clashes of proposed new works with other assets shallbe reported to the Superintendent immediately forclarification.

24. Clearances to other services shall be as per Table 7 andTable 5.5 of WSA03- 2011 MRWA edition. These clearancesshall apply to surface covers as well as underground assets.

shall not commence until earthworks and retaining walls hasbeen completed unless written approval has been given bythe Water Authority.

Testing, Asset Acceptance and Live Connections26. Post construction activities (of both DW & NDW) such as

swabbing, water quality testing, pressure testing andchlorination shall be carried out in accordance withWSA03-2011 MRWA edition and the MRWA Water QualityCompliance Specification.All test results shall be documented and reported to theSuperintendent.

27. The Water Agency shall be notified in writing 2 full workingdays in advance of testing being undertaken.

28. Both ends of DW and NDW main to meter property servicesshall be inspected by the Water Agency.The Water Agency shall be notified in writing 2 full workingdays in advance of this inspection being carried out.Both ends of DW-NDW main to meter property services areto remain exposed until inspected by the Water Agencycompliance officer. (Remove this note if not a Dual Waterdesign).(insert if YVW)- Each property service shall be "squirttested". This test involves placing each network underpressure separately and ensuring that only the end of thecorrect property service discharges water.

29. The Contractor's ITP shall include provision for each NDWconnection to be signed off as correctly installed.(Remove if not a Dual Water design).

30. The Water Agency shall be notified in writing 5 (if CWW orSEW) / 9 (if YVW) full working days in advance ofconnection to the live network being undertaken.Shut down work shall be as short as practical and scheduledto commence at 9am on working days with completion tooccur no later than 4pm.In industrial and commercial areas, the impact on businessshall be considered and it may be necessary to carry out thework outside normal working hours.

NOTES to the Designer.

1. Design details (such as those displayed here) are required whenever there are more than 6 items within close proximity (ie: 5m

diameter circle) or whenever a non standard arrangement is proposed .

An "item" is a restraint block or any hydraulic item which has a separate entry in the products catalogue.

A continuous unchanging length of pipe is considered one item.

2. These detailed drawings are for example purposes only, and while they represent good practice, they are not suitable to be used

without customization.

3. Schematic drawings should be approximately to scale.

4. The designer is to designate when water mains are to go under drains & sewers.

5. Water mains should cross over drains and sewers if possible.

6. Gas main alignments are indicative only. Refer to gas authority for gas asset requirements.

7. Show all road, footpath, driveway, drainage, gas, electricity and communications assets where they are close (within 1m) inc

crossings (if available), plus:

· All Individual items as defined in note 1.

· Distances between items or the position of items relative to surveyed markers (eg: position relative to property boundaries),

· Side entry pits and any other surface features such as Other Authority covers.

GENERAL NOTES:1. The schematics in this drawing are intended to illustrate how component parts of the water supply

system can be drawn.The schematics do not describe requirements for locating component parts of the system and are notto be used or quoted in designs.

2. Dead ends > DN100 (on residential supply) and > DN150 (on industrial / commercial supply) are onlyacceptable on a temporary basis.

3. For end of line PE pipework refer to drawing MRWA-W-108.4. Where PE is available off a roll (ie: DN63PE) it shall be used to reduce jointing.5. Storage of pipe and fittings must be kept clean and dry as much as practical.

Fittings must be stored in plastic bags or boxed before use.6. Before and after pipe laying, exclusion caps, plugs or blank flanges must be fitted to pipe ends to

prevent contamination.7. Connection of PE to CIOD sized mains requires specific design and will sometimes require custom

made stub flange &/or backing ring &/or reducer. Refer to MRWA-W-306B for details.

3 TABLE 104-A, RESTRAINT AT BENDS, TIES 01/12/16 RJ / CP / JT

GENERAL PRINCIPALS OF PIPE RESTRAINT:1. All valves connected to unrestrained pipework on one side must be restrained with a concrete restraint (as restrained pipework

immediately downstream on the other side of the valve may be cut at some stage).2. Restrained main options maybe necessary where:

2.1. Thrust restraints cannot be placed against a bearing surface of adequate allowable horizontal bearing pressure (ie: AHBP <50kPa), or

2.2. There are inappropriate conditions (ie: obstructions) at the fitting for a thrust restraint.3. Inline thrust restraints can be used off the branch of a tee instead of a plain restraint behind the tee, provided the pipework between

the tee's offtake and the inline restraint is fully restrained (ie: has no unrestrained joints).4. Vertically cantilevered restraints may be used instead of normal restraints where the ground to the sides of the trench is inadequate

but the ground underneath the trench is adequate, or where other obstructions make the use of a normal restraints impracticable.

To counter rotational forces on the bends at location A (which may be a problem with a flexible main likePE), and provided the main to either side of the dog leg is in line, size the in line restraints as follows: Thermal contraction + Poisson's + (Restraint area for Bend A (as if plain anchour) x Sin( )).Restraints may not be required at all for very short lengths of PE.When the main on either side of the dog leg is not co-linear, increase the size of the thrust restraints tocompensate for the net change in direction as per MRWA-W-204.

NOTES Regarding Table 104A-A & Figures 104A-A to F:1. The designer shall minimise the number of Options A, B or C used and

the amount of changing between one option and another.2. Where the majority of the design is Option A (RRJ) pipework, Option B or

Option C pipework is typically only be introduced when:2.1. The ground behind the fitting is disturbed or weak (ie: there is a

drain or other service behind the fitting),2.2. There is an obstruction in front of the fitting (ie: drain) which

prevents dual water mains being staggered to a greater depth,2.3. There are two opposing fittings too close together to be able to

install a plain restraint behind both fittings (ref Figures 140B-A & B).3. Where one of these situations occurs, restrained pipework shall be

specified between Tees and splay valves to eliminate the need for plainthrust restraints.

4. The designer shall indicate:4.1. restrained pipework with bold linework (3 x normal thickness), and4.2. indicate suitable joints in any detailed design schematics.4.3. indicate suitable pipe types for all (even short) sections.

5. Option B (PE) shall be the default restrained pipework option for sizes< DN355 (provided there is no ground contamination risk).In line thrust restraints shall be sized to accommodate the valve thrust +PE thermal shrinkage thrust (worst case scenario).

6. Where PE pipework (Option B) has been selected in the design, thecontractor may choose any Water Agency approved Option C pipe andjointing option and then:6.1. Construct in line restraints to the size nominated in the design

(which may have a contribution of PE shrinkage built in), or6.2. Apply to the designer to have the PE shrinkage contribution

removed from the restraint size where the restraint area is > 2m².Design changes of this type do not need to be submitted to the wateragency for acceptance / approval.

7. Where Option B (PE) pipework is not suitable and < DN355 Option Cpipework is indicated in the design, the Contractor may select any WaterAgency approved Option C pipe and joint combination.

Where a drain is tooshallow to enable thedepth of dual water mainsto be staggered, plainanchors shall not bespecified

>800 &ACAP

Ensure valves areclearly in pavement(ie: valve surroundsnot within kerb andchannel)

Where a drain is tooshallow to enable thedepth of dual water mainsto be staggered, plainanchors at the Tee shallnot be specified

GENERAL NOTES:1. Where the distance between bends is less than that shown in Table

104B-A, restrained pipe must be used between the two bends asoutlined in MRWA-W-104A.

2. Typically, where dual water bends and tees occur within the vicinityof more than one other service (ie: power, gas, communications,drainage or sewerage), concrete thrust restraints are not practicaland shall not be specified.

3. Adjacent dual pipe plain thrust blocks cannot be used when the teesor bends are closer together than the distance indicated in Table104B-A.

4. No vertical fabricated bends or vertical concrete thrust restraints arepermitted between adjacent bends or tees.

5. There are a number of ways of using restrained pipe and an in linerestraints for restraining dual water tees.Refer to MRWA-W-104A and MRWA-W-205B for examples.

GENERAL NOTES:1. Main sizes provided for example purposes only.2. For corrosion protection of metallic mains, refer to drawings MRWA-W-306A & 400 and WSA03.3. All large main (> DN300) tee offtakes shall be flanged, with a valve always bolted to this flange.4. Lengths shown with welded collars are MSCL pipe, cut to length & welded in situ.

Refer to drawing MRWA-W-400 for details.5. Direct property service connections are not permitted on mains > DN375.6. Gibaults and adaptaflanges (uniflanges) are not permitted on new mains unless otherwise approved.

Thrust type dismantling joints are acceptable in non buried applications.7. Slip on or welded steel flanged pipe must be fabricated in an ISO-9001 accredited metal fabrication workshop

(not on site) .8. Locate > DN450 divide valves at distinct low and high points where practical.9. Scours are often best located at distribution divide valve bypass pipework, particularly where the > DN450

divide valve is located at a distinct low point. Refer pipework in blue.10. Scours are usually sized as bypass valves (refer to Table 105-A).11. Refer to MRWA-W-307 for details on scours.12. Air valves may be required in addition to the hydrant on the bypass. Refer to MRWA-W-304.13. Valves and hydrants / air valves shall be separated by > 800.

NOTES Regarding Figure 105-A:1. Welded MS pipework shown.2. May be butt welded if PE.

One EF joint permitted as a final connection of the bypass pipework to the main.Ensure that the pipework either side of any EF weld is perfectly aligned prior to EFwelding.

3. All sections of MS main (ie: sections between valves) need to be covered by the cathodicprotection design and have test points constructed accordingly.

NOTES Regarding Figure 105-B:1. Pipework shown in red shall be welded steel. Provide coatings as per drawings MRWA-W-306A & 400. Cathodic protection of these short lengths is not required.2.

THRUST ANCHOR REQUIREMENT

> DN375 SAME SIZE, 1 OR 2 SIZE REDUCED OFFTAKES REQUIRE ANCHORING

NOTES Regarding Clamp Connection Anchor Blocks:· Example: for a DN600 parent main with DN450 branch, an anchor would be required.· Thrust anchors are not required where the branch main is a restrained pipeline. Refer MRWA-W-104A.· Anchor bearing areas for stainless steel full wrapped clamps shall be > 0.5 of the area calculated using MRWA-W-204.· The branch can only be made live (connection valve opened) after the curing time of the concrete has lapsed (a rapid set

concrete (ie: Fosroc or CTS Rapidset with a cure time of 1hr) may be required to hasten the mains return to service).

Under Pressure Connections:A. Stainless Steel full wrapped clamps not guaranteed by the

manufacturer as suitable for PVC-O / PE host mains shall not beused in such applications.

B. Connections must be pressure tested at the operating pressureplus 400 kPa (to a max of 1600 kPa) for 3 minutes prior to cutting ofthe host main coupon.

C. Do not use under pressure connections on GRP pipe.D. Under pressure connections are permitted on A.C and Cast Iron

water mains provided the main's condition is satisfactory (nosignificant corrosion, cracking or shape distortion) and WaterAgency approval is obtained.

E. Under pressure connections on wrought iron, riveted or locked barmains require prior inspection and approval from the Water Agency.

F. All valves shall be left in state where they can be operated fromabove ground (unless stated otherwise).

G. Offtake mains of the same size as the host main are permitted, butcoupons shall be sized as per Table 106-B.

H. When assembling SS off-take clamps on plastic pipes, ensure thatlubricant is applied to the elastomeric mat of the clamp.

I. Refer to Appendix C of WSA03- 2012 MRWA edition for furtherinformation on under pressure connections.

J. Under pressure connections to rear dual water mains shall beundertaken in one of the following ways (control thrust whererequired as per MRW-W-104A & 104B):· the tee may "point backwards", join to a valve and then with a 90

degree downward bend and another 90 degree horizontal bend,pass under the front main (this is the preferred method):

· the offtake may be constructed in a downwards direction, to avertically aligned valve which is used for the under pressureconnection and then buried in the open position.If an operable valve is required at the offtake (ie: host main is> DN300), join to the valve a FL-FL (or WC) 90° vertical bend andconnect this to an offset horizontal valve which shall be operablefrom surface.

INSTALL 0.4 mm PLASTIC MEMBRANEBETWEEN CONCRETE & CLAMP.

CUT-IN CONNECTION METHODS

FIGURE 106-A: DI, CAST IRON, A.C, PE, PVC-M OR PVC-UHOST MAIN UNDER PRESSURE CONNECTION

KEY REFERENCES:· Pipeline and flange corrosion protection as per MRWA-W-306A and 400.· Flanges in accordance with MRWA-W-306A & 306B.· Restraints are to be designed and constructed according to MRWA-W-205A & 205B.· In line thrust restraints may be used on branches instead of plain blocks (refer

MRWA-W-104A).

TEMPORARY ASSEMBLY(REDUCED SIZE)

GENERAL NOTES:1. To minimise risk and disruption to customers, Tapping Under Pressure

Connections are preferred, especially where shutting down the host main wouldbe difficult, costly or would affect a large number of customers.

2. All valves fitted to existing mains shall be successfully pressure tested to theoperating pressure plus 400 kPa for 3 minutes prior to being fitted.

3. Offtake valves shall only be opened once all acceptance testing of the offtakemain have been successfully undertaken.

4. Fire service and industrial commercial connections >- DN100 shall be constructedin this way.

5. Where a tee is cut-in, a thrust block is required where the mechanical couplings(ie: gibaults) are unrestrained, even if the branch pipeline is restrained.

6. The piece of main removed (coupon in the case of under pressure connectionsor short length of main in the case of cut in connection) shall be forwarded to theWater Agency if there is any sign of significant corrosion, erosion or cracking.

GENERAL NOTES:1. For PE main tapping saddle/ band jointing preferences, refer to Table 103-D.2. Another acceptable option is to cut in a flanged offtake tee & use a tapped blanked flange to connect to a PE main

(refer Figure 109-B).3. Maintain a minimum 500 longitudinal spacing (between outside of fittings) between tapping bands, saddles,

pre-tapped connectors and/or pipe joints, except for existing PVC-U, cast iron and asbestos cement pipes wherespacings should be in accordance with water agency requirements (based on pipe condition).

4. All options shown (except Figure 107-C) are suitable for under pressure connections.5. DN40PE, DN50PE and DN63PE industrial, commercial and multiple dwelling connections shall be constructed in

this way.6. Ferrules require adaptor or compression fittings to connect to PE.7. All gate valves shall be operable from surface with surface fittings as per MRWA-W-302.8. All ferrules shall be buried unless:

8.1. they are located under reinforced concrete.8.2. they are for fire service connections.In these cases, they shall be operable from surface and be provided with a surface cover (Fitzroy box).

9. Where multiple connections of this type are made, neighboring tappings shall be at least 15 degrees different intheir vertical orientation (so that holes do not line up).

10. Bare metal fittings are not to be used in corrosive ground (soil resistivity > 500 ohm.cm) unless they are wrappedwith a petrolatum wrapping system.Refer to MRWA-W-306A for details.

11. Steel mains with DN40-63PE offtakes shall be tapped as per MRWA-W-400 (insulation not required)

NOTES on Table 110-A and Figures 110-D to H:A. Examples of how these rules can be applied to determine optimum property service alignments can be

found in MRWA-W-102A.B. An allowance for trees shall be made for all lots >10m wide.C. Tappings shall not be installed under pavement or proposed trees unless impractical to do otherwise.D. Tappings between driveways and proposed trees are only acceptable in lots > 16m wide.E. End of property services shall be kept clear of pavement.F. End of property services shall be kept clear of proposed trees where Table 110-A preferences allow.G. Where building envelope front offset <1m, services are to terminate at the front boundary.H. GPS co-ordinates of each end of the conduits to be provided with the as constructed information.

I. These dimensions assume there is no retaining wall at the front of the lot.Where there is a retaining wall, refer to MRWA-W-214.

J. The tapping preferences set out in Table 110-A are based on pre-tapped connectors being used (ie: thatthe main is RRJ).For PE reticulation mains, tappings are single port and so only preference one in Table 110-A isrelevant.

K. Where the service is not at 90 deg, provide detectable marking tape from the tapping, through theconduit to the end of the service connection valve and run vertically to surface.

L. Keep water conduits clear of other authority pits.Use a single long radius bend (R> 1m) in each conduit as required to avoid these structures.

NOTES:1. Residential property services shall typically be DN25PE.2. Larger services > DN40PE shall be connected as shown in MRWA-W-106 & 107.3. For PE main tapping saddle/ band jointing preferences, refer to Table 103-D.4. Only install pipe joiners if approved by the water agency.5. Maintain min 500 longitudinal spacing (between outside of fittings) between tapping bands, saddles,

pre-tapped connectors and/or pipe joints, except for existing PVC-U, cast iron and asbestos cementpipes where spacings should be in accordance with water agency requirements (based on pipecondition).

6. Service connections not permitted under drive ways.7. Service connections under reinforced concrete and all fire service connections <DN00 shall use a ferrule

with Fitzroy box surface cover.Ferrule bends shall be used to set the correct angle of the property service.

8. Service pipe shall only be bent in accordance to the limitations described in PIPA document POP202.9. Tapping fitting must be orientated between vertical (line above the main) and the horizontal line (towards

the property being serviced).10. All male threads shall be wrapped in PTFE tape.11. Isolation valves at the tapping shall be left open after installation.12. Bare metal (gun metal / SS) shall not be used in corrosive ground (soil resistivity > 500 ohms.cm) unless

components are wrapped with a petrolatum wrapping system.Refer to MRWA-W-306A.
