WATER SYSTEM DESIGN STANDARDS

I. PURPOSE

To provide guidelines for the design of water utilities projects and thereby reduce thetime required for processing the plans. These guidelines do not include, but mayreference, additional conditions which may be promulgated by all other pertinentordinances, codes, and official policy set forth by Special Districts Administration orother departments of the County of Lake or other government agencies. Theseguidelines establish minimum acceptable design criteria. More stringentrequirements may be imposed by the Administrator based on specific projectconditions.

Portions of these standards apply to fire systems, both public and private, and areintended as general reference to aid in the design of the public water system. Finaldesigns are subject to approval of the local fire agency.

It is the responsibility of the design engineer to initiate written requests to theAdministrator for approval of any design concepts that differ from these criteria,verify additional requirements imposed, perform any necessary calculations orstudies, and resolve specific design problems with the appropriate agency,department or division.

II. REQUIREMENTS FOR IMPROVEMENT PLANS AND SUBDIVISION MAPS

A. Provide a detailed utility plan showing onsite and offsite public andprivate water and fire protection systems, including mains, services,hydrants, and all other required appurtenances, and their connectionsto existing County-maintained water facilities. Show the location, type,and diameter of public and private water mains. Reference any existingfire hydrants within 300' of the project boundary. Show any wellsexisting or to be abandoned. When a separate irrigation service isnecessary, an irrigation plan is required per section X-O of thesestandards. (See section XI-B for submittal of plans for private firesystems.)

- 1 -

B. Annotate the local agency information sheet of the Subdivision Mapwith any information that is needed to notify property owners ofrequirements for connection to the County water system. Theseinclude, but are not limited to:

1. payment of fees prior to issuance of Building Permits,2. lots requiring pressure regulating valves or booster

pumps,3. backflow protection,4. public water access requirements, such as gates or

access roads.The appropriate information may be obtained from Special Districts.

C. Miscellaneous specific items required on improvement plans areindicated throughout these Standards.

D. Before combustible materials may be delivered, stored or constructed on site,fire flow and access must be provided and approved by the local fire agencyper current County Fire Code. In addition, public and/or private fire hydrantsmust be installed, flushed, tested, and operational. This information must beincluded on all improvement plans. Provide any necessary calculations withthe submittal of improvement plans or with the Tentative Map submittal todemonstrate adequate fire flows are available.

III. WATER MAINS - GENERAL

A. Public water mains may not be designed outside the public right-of-waywithout Administrator approval.

B. In general, publicly maintained water systems will be designed onlywhere they serve multiple ownership lots and where appropriate accessfor maintenance can be provided.

C. Water mains installed at a slope of 15% or greater will be designed withrestrained joints. The Design Engineer must provide adequatedrainage measures to protect the trench from erosion.

D. Water mains installed outside of any roadway, referred to as cross-country mains, must be Ductile Iron Pipe and will have suitable access.In general, cross-country mains must be isolated with valves in thepublic right-of-way and must be identified with blue locating posts(Carsonite 492 CW-112 or approved equal) at approximate 500'

- 2 -

intervals, at any angle point, and at the entrance to an easement.Stakes should have vandal-proof metal bottoms. Access requirementsmay be imposed on a project based on site conditions.

E. For system reliability, to minimize pipe size, and to minimize thenumber of people affected by a system shutdown, either for domestic orfire protection purposes, no more than 100 residential units may beserved by a single-feed water system, provided it is hydraulicallyadequate. Where more than 100 units are to be served, a dual-feed(loop) public water system must be designed to provide a secondarysource of water to the project. Onsite private fire requirements, such asdual fire services and looping mains, will be determined by the local fireagency for residential and nonresidential developments.

F. For purposes of leak detection and maintenance access, no reinforcedconcrete may be designed over publicly maintained water facilities.Unreinforced concrete will be allowed under special circumstancessuch as crosswalks.

G. For the purpose of locating buried pipe, electrically continuous tracewire of #10 copper with thermoplastic insulation of the direct burial typeshall be installed on all water mains and service lines. Wire connectorsshall be watertight to provide electrical continuity. Trace wire to beinstalled in the same trench during pipe installation and secured flat, at10' intervals, to the pipe to ensure the wire remains adjacent to thepipe. Access points shall be no greater than five-hundred (500) feetapart.

H. Extent of water main improvements will be as follows:1. Any offsite water main improvements needed to serve the project

must be shown on the improvement plans, including upgrades toexisting mains that may be required as a result of a flow analysisor modeling effort.

2a. In general, water mains must be designed at least across one-half of the property frontage or to the last service connection,whichever is greater; or

2b. Where the project is required to provide new streetimprovements over the water main alignment and the water mainwill serve properties beyond the project limits, the water mainmust be designed to cross the full property frontage or to thelimits of the street improvements, whichever is greater.

- 3 -

I. Streets with both water and sewer mains must be at least 20 feet wide,face-of-curb to face-of-curb; one utility only: at least 16 feet wide; nowater or sewer mains in alleys.

IV. MATERIALS

B. Indicate connection of pipes 4" -12" in diameter with a hot tap or a cut-in tee in conformance with the provisions of the Water SystemConstruction Standard Specifications Section 1-1.20. Hot taps will beallowed only when no main line valves are required, always install atee.

C. Design a cut-in tee if additional valves are required on the existingmain. If the new main/connection is larger than the existing main, the

- 4 -

tee and main/connection valve will be the size of the existing mainunless it is hydraulically necessary to increase the tee and valve to thesize of the new main/connection.

D. Tie-ins to the existing County water system must be inspected by aSpecial Districts representative and the improvement plans must be soannotated.

E. Size-on-size taps are allowed up to 8" in accordance with the approvedstandards. 12" size-on-size taps are allowed only under emergencysituations and with the specific approval of the Administrator.

XI. PUBLIC IMPROVEMENTS FOR PRIVATE FIRE SYSTEMS

A. Design plans showing private fire systems must be submitted to theappropriate Fire and/or Building jurisdiction for approval and 1) may beincluded with the Public Improvement Plans for the project, or 2) copiesof the approved plans maybe submitted to Special Districts prior torequesting a meter set and activating the fire system.

B. !i< Generally, the connection size must be designed the same size orlarger than the size required for the fire sprinkler system and/or theprivate hydrant system. Caution - onsite fire system design maynecessitate changes to pre-approved public improvements. Thehydraulic calculations for connections serving private fire systems willbe based on t~e required fire flow or the fire sprinkler demand,whichever is greater, combined with the peak domestic flow.

C. All private fire systems that only serve onsite hydrar:lts requireaboveground single detector check valves in accordance with Standard888. Where aboveground installations are not reasonable due to siteconstraints, design for single detector check valves in. vaults perStandard 879.

D. Double-check detector backflow assemblies are required for:

1. all connections serving commercial fire sprinkler systems; or

2. any property with multiple fire service connections; (X

3. any fire line connections to properties with auxiliary water supply.

F. Reduced-pressure detectors are required for:

1. any fire line utilizing chemical additives such as antifreeze or firesuppressants; or

2. any building where an extreme hazard exists.

G. For one- and two-family residential fire sprinkler systems:

- 13 -

1. Where the multipurpose water system circulates for firesprinklers and domestic supply, no backflow device is required.

2. Where the fire system does not circulate water,with the domestic '.supply, double-check backflow assemblies must be designed,where the fire system connects to the domestic system. Design

.~\ L the .backflow assembly as close as possible to the \'Vatermeter...:'~••~.~ . ~ .', 'I ~ ~

3. ,!~ : Where a fire sprinkler system is to be installed in a one- or two--family dwelling,design the servi~ connection from the streetmain to the water meter and the water meter to be 1" minimum .

Memorandum

Date: April 14, 2003 (Revised Date: October 16,2003)

To: Regional and District Engineers

From: David P. Spath, Ph.D., Chief (Original signed by Dave)Drinking Water and Environmental Management 601 North 7th Street, MS216

Sacramento, CA 95814(916) 322-2308

Subject: GUIDANCE MEMO NO. 2003-02: GUIDANCE CRITERIA FOR THESEPARATION OF WATER MAINS AND NON-POTABLEPIPELINES

The purpose of this memo is to update guidance dated April 5, 1983 forconsistency with proposed 2003 regulations. Should there be any modification tothe proposed Water Works Standards that may impact the content of this guidance,the guidance will be amended accordingly.

GUIDANCE: CRITERIA FOR THE SEPARATION OFWATER MAINS AND NON-POTABLE PIPELINES

BACKGROUND

When buried water mains are in close proximity to non-potable pipelines, thewater mains are vulnerable to contamination that can pose a risk of waterbornedisease outbreaks. For example, sewers (sanitary sewer mains and sewageforce mains) frequently leak and saturate the surrounding soil with sewage due tostructural failure, improperly constructed joints, and/or subsidence or upheaval ofthe soil encasing the sewer. If a nearby water main is depressurized and nopressure or negative pressure occurs, that situation is a public health hazardthat is compounded if an existing sewer is broken during the installation orrepair of the water main. Further, failure of a water main in close proximity to otherpipelines may disturb their bedding and cause them to fail. In the event of anearthquake or other disaster, simultaneous failure of all pipelines could occur.

The most effective protection against this type of drinking water contamination isadequate construction and separation of non-potable pipelines and water mains.The Waterworks Standards (Title 22, Chapter 16, Section 64572) provideseparation criteria for new construction. However, when these criteria cannotbe met, the risk of contamination can be reduced by increasing the structuralintegrity of pipe materials and joints, and ensuring minimum separation

22

requirements are met. Therefore, the following guidance details constructioncriteria for the installation of water mains and non~potable pipelines tominimize the risk of contamination of drinking water.

DEFINITIONS

• COMPRESSION JOINT - A push-on joint that seals by means of thecompression of a rubber ring or gasket between the pipe and a bell o~coupling.;

• CONTINUOUS SLEEVE - A protective tube of high-density-polyethylene(HOPE) pipe with heat fusion joints or other non-potable metallic casirg withoutjOints into which a pipe is inserted. 1

• DISINFECTED TERTIARY RECYCLED WATER - Wastewater' that hasbeen filtered and subsequently disinfected in accordance with Section60301.230, Chapter 3 (Water Recycling Criteria), Title 22, Californi;:l Code ofRegulations. '

• HOUSE LATERAL - A sewer line connecting the building drain and thesanitary sewer main serving the street.

• SUPPLY LINE - Pipelines conveying raw water to be treated for drinkingpurposes in accordance with Section 64572 @, proposed Water WorksStandards. .

• WATER MAIN - Means any pipeline, except for user service lines, within thedistribution system in accordance with Section 64551.70, proposed Water WorksStandards.

• RATED WORKING WATER PRESSURE - A pipe classification system basedon internal working pressure of the fluid in the pipe, type of pipe material, andthe thickness of the pipe wall.

• SANITARY SEWER MAIN - A gravity sewer conveying untreatedmUl'licipal wastewater.

• SEWAGE FORCE MAIN - A pressurized sewer conveying untreatedmunicipal wastewater.

23

APPLICABILITY

Note that the construction criteria presented in this document apply to house lateralsthat cross above a water main, but not to those house laterals that cross below a watermain.

Water mains or non-potable pipelines that are 24-inches in diameter or larger may posea higher degree of public health concern because of the large volumes of flowinvolved. Therefore, installation of water mains or non-potable pipelines 24-inches indiameter or larger should be reviewed and approved in writing by the Department on acase-by-case basis prior to construction.

REGULATORY REQUIREMENTS

Any new development project in which all the underground facilities are beingconstructed for the first time must comply with the following regulatory requirements:

Existing requirements:

Section 64630. (Title 22 CA Code of Regulations) Water Main Installation.(c) Water mains shall be installed at least:

(1) Ten feet (3 meters) horizontally from and 1 foot (0.3 meters) higherthan sanitary sewer mains located parallel to the main.(2) One foot (0.3 meters) higher than sanitary sewer mains crossing themain.(3) Ten feet (3 meters), and preferably 25 feet (7.5 meters), horizontallyfrom sewage leach fields, cesspools, seepage pits and septic tanks.

(d) Separation distances specified in (c) shall be measured from the nearestoutside edges of the facilities.

(e) Where the requirements of (c) and (d) cannot be met due to topography,inadequate right-of-way easements, or conflicts with other provisions of theseregulations, lesser separation is permissible if:(1) The water main and the sewer are located as far apart as feasible withinthe conditions listed above.(2) The water main and the sewer are not installed within the same trench.(3) The water main is appropriately constructed to prevent contamination ofthe water in the main by sewer leakage.

(f) Water mains shall be disinfected according to AWWA Standard C601-81before being placed in service.

(g) Installation of water mains near the following sources of potentialcontamination shall be subject to written approval by the Department on a case-

24

by-case basis:(1) Storage ponds or land disposal sites for wastewater or industrial processwater containing toxic materials or pathogenic organisms.(2) Solid waste disposal sites.(3) Facilities such as storage tanks and pipe mains where malfunction ofthe facility would subject the water in the main to toxic or pathogeniccontamination.

Although the following requirements have not yet been adopted, they shouldbe within the next two years and should be used as guidance for futureconstruction.

Proposed requirements as of the date of this document:

Section 64572. Water Main Separation(a) New water mains and new supply lines shall not be installed in the same trench

as, and shall be at least 10 feet horizontally from, and one foot vertically above, anyparallel pipeline conveying:

(1) Untreated sewage,(2) Primary or secondary treated sewage,(3) Disinfected secondary-2.2 recycled water (defined in section60301.220),(4) Disinfected secondary-23 recycled water (defined in section 60301.225),and(5) Hazardous fluids such as fuels, industrial wastes, and wastewatersludge.

(b) New water mains and new supply lines shall be installed at least 4 feethorizontally from, and one foot vertically above, any parallel pipeline conveying:

(1) Disinfected tertiary recycled water (defined in section 60301.230), and(2) Storm drainage.

(c) New supply lines conveying raw water to be treated for drinking purposes shall beinstalled at least 4 feet horizontally from, and one foot vertically below, any watermain.

(d) If crossing a pipeline conveying a fluid listed in subsection (a) or (b), a newwater main shall be constructed perpendicular to and at least one foot above thatpipeline. No connection joints shall be made in the water main within eight horizontalfeet of fluid pipeline.

(e) The vertical separation specified in subsections (a), (b), and (c) is requiredonly when the horizontal distance between a water main and pipeline is ten feet orless.

25

(f) New water mains shall not be installed within 100 horizontal feet of anysanitary landfill, wastewater disposal pond, or hazardous waste disposal site, orwithin 25 feet of any cesspool, septic tank, sewage leach field, seepage pit, orgroundwater recharge project site.

(g) The minimum separation distances set forth in this section shall be measuredfrom the nearest outside edge of each pipe barrel.

ALTERNATIVE CRITERIA FOR CONSTRUCTION

Water Mains, and Sewers and Other Non-potable Fluid-carrying PipelinesWhen new water mains, new sanitary sewer mains, or other non-potable fluid-carryingpipelines are being installed in existing developed areas, local conditions (e.g., availablespace, limited slope, existing structures) may create a situation in which there is noalternative but to install water mains, sanitary sewer mains, or other non-potablepipelines at a distance less than that required by the regulations [existing Section 64630(proposed Section 64572)]. In such cases, through permit action, the Departmentmay approve alternative construction criteria. The alternative approach is allowed underthe proposed regulation Section 64551 (c):

"A water system that proposes to use an alternative to the requirements in thischapter shall demonstrate to the Department how it will institute additional mitigationmeasures to ensure that the proposed alternative would not result in anincreased risk to public health."

Appropriate alternative construction criteria for two different cases in which theregulatory criteria for sanitary sewer main and water main separation cannot be met areshown in Figures 1 and 2.

• Case 1 - New sanitary sewer main and a new or existing water main; alternativeconstruction criteria apply to the sanitary sewer main.

• Case 2 - New water main and an existing sanitary sewer main;alternative construction criteria may apply to either or both the water main andsanitary sewer main.

28

Water Mains and Pipelines Conveying Non-potable Fluids

When the basic separation criteria cannot be met between water mains and pipelinesconveying non-potable fluids, the requirements described above for sanitary sewermains should apply. This includes the requirements for selecting special constructionmaterials and the separation requirements shown in Figures 1 and 2. Note that not allconstruction materials allowed for sanitary sewer mains will be appropriate for othernon-potable fluid lines. For example, certain plastic lines may not be appropriate forthe transport of some fuel products. The selection of compatible materials ofconstruction for non-potable fluids is a decision to be made by the project engineer.

Water Mains and Sewage Force Mains

• Sewage force mains shall not be installed within ten feet (horizontally) of awater main.

• When a sewage force main must cross a water main, the crossing should beas close as practical to the perpendicular. The sewage force main should be atleast one foot below the water main.

• When a new sewage force main crosses under an existing water main, and aone-foot vertical separation cannot be provided, all portions of the sewage forcemain within eight feet (horizontally) of the outside walls of the water mainshould be enclosed in a continuous sleeve. In these cases, a minimum verticalseparation distance of 4 inches should be maintained between the outsideedge of the bottom of the water main and the top of the continuous sleeve .

• When a new water main crosses over an existing sewage force main, thewater main should be constructed of pipe materials with a minimum ratedworking pressure of 200 psig or the equivalent.

Water Mains and Tertiary Treated Recycled Water or Storm Drainage

The basic separation criteria for water mains and pipelines conveying tertiary treatedrecycled water or storm drainage lines are a 4-foot horizontal separation where lines arerunning parallel and a 1-foot vertical separation (water line above recycled or stormdrainage) where the lines cross each other.

When these criteria cannot be met, the Zone A criteria apply where lines are runningparallel, and the Zone C and Zone 0 criteria apply where the lines cross each otheras shown on Figures 1 and 2. For these situations, the Zone "P" criteria are in effectand prohibit construction less than 1 foot in parallel installations and less than 4inches in vertical (crossing) situations.

29

For tertiary treated recycled'water and storm"drain~ge linE;!s,th~Zqn~_.B ,criteria(requirements for special pipe) do not apply as the basic separation criteria is a four-foothorizontal separation criteria for parallel lines. The tertiary treated recycled water'lines "should be constructed in accordance. with the color-coding, and labeling requirementsper Section 116815, California'Health and Safety Code of Regulations.

For push on tees, the tee, valve and concrete thrust block must be removed and the mainrepaired with approved pipe and suitable couplings.

1-1.18 Hydrostatic Test

The test shall be performed after the water system has been laid and all backfill placed andcompacted as specified elsewhere in these specifications. The Contractor, at his option, maytest the pipe at any time during construction. However, the final test for acceptance shall bemade only after all backfill is in place.

Pressure testing against valves is not allowed unless authorized by the Administrator.Valves on existing pipes in service shall be operated only by District forces.

Each section of pipe shall be slowly filled with water and the specified test pressure shall beapplied by means of a pump connected to the pipe in a satisfactory manner. The pump, pipeconnection, and all necessary apparatus including gauge and measuring devices shall befurnished by the Contractor. The Contractor shall make the taps into the pipe and shall furnishall necessary assistance for conducting the tests. Before applying the test pressure, all air shallbe expelled from the pipe. To accomplish this, taps shall be made, if necessary, at the points ofthe highest elevation, and afterwards tightly plugged.

Each valved section of pipe, or combined sections, as approved by the Administrator, shall besubjected to a hydrostatic pressure of not less 50 psi above working pressure and not less than150 psi at any point on the pipe. The duration of each pressure test shall be thirty minutes.

Suitable means shall be provided by the District for determining the quantity of water leakageunder test pressure. No pipe installation will be accepted until or unless this leakage is lessthan 40 U.S. gallons per 24 hours, per mile of pipe, per inch nominal diameter of pipe.

Should any test of combined or individual sections of pipe disclose leakage greater than thespecified limit, the Contractor shall, at his own expense, locate the cause and repair the defectuntil the leakage is within the specified allowance.

Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any valvedsection of it, necessary to maintain the specified leakage test pressure after the pipe has beenfilled with water and the air expelled. The Administrator shall designate the time at which thetests shall be made.

The Contractor shall repair any obvious leaks even though the hydrostatic test results are withinthe prescribed limits above.

1-1.19 Chlorination of Pipeline

Chlorine may be applied by any of the standard methods, subject to the approval of theAdministrator. The point of application of the chlorinating agent shall be at the beginning of thepipe extension, or any valved section of it, and through a corporation stop inserted in the newlylaid pipe.

38

Water from the existing distribution system shall be controlled to flow very slowly in the newlylaid pipe during the application of chlorine. Precautions shall be taken to prevent back pressurecausing a reversal of flow into the pipe being treated. In the process of chlorinating, all valvesand other appurtenances on the new pipe shall be operated in such a way as to provide that thechlorine mixture shall be fully distributed to all parts of the new water system. Valves on existingpipes in service shall be operated only by District forces.

The rate of chlorine feed shall be in such proportion to the rate of water entering the pipe thatthe chlorine dose applied to the water entering the newly laid pipe shall be at least 100 ppm.

The chlorine mixture shall be retained in the pipe for a period of twenty-four hours. After thechlorine mixture has been retained for the required time, the chlorine residual at the pipeextremities and at representative points shall be at least 5 ppm.

Following chlorination, all chlorine mixture shall be thoroughly flushed from the new pipe.Chlorinated water used to disinfect the pipe is the property of the Contractor and its disposal isthe responsibility of the Contractor. Chlorinated water used to disinfect the pipe shall bedisposed of in accordance with all laws and regulations.

The following criteria must be met prior to disposal of chlorinated water to storm sewers or otherinland waterways:

• Water to be disposed of must contain no chlorine residual.• pH must be between 6.5 and 7.5.• Central Valley Regional Water Quality Control Board must be notified of discharge.

Discharges not meeting the above criteria may be allowed to be disposed of into the sanitarysewer system, but must first meet the following requirements:

• The Contractor must obtain permission from Special Districts, (707) 263-0119, prior tothe discharge being disposed of in the sanitary sewer system. The payment of any feesrequired will be the responsibility of the Contractor.

• The pH of the water must be between 6.0 and 9.5.

Should the initial treatment, in the opinion of the Administrator, prove ineffective, the chlorinationprocedure shall be repeated until confirmed tests show that the water sampled from the newlylaid pipe conforms to the above requirements.

The initial bacteria samples will be taken and tests made by Special Districts. There shall be a24 hour waiting period after blowing off the pipe prior to taking bacteria samples. If the initialbacteria test fails, two consecutive passing bacteria tests must be obtained prior to making thetie-in. If additional testing is required, it will be necessary for the contractor to arrange for and topay for the tests at a State of California certified laboratory. In extreme cases, at the discretionof the Administrator it may be necessary to require, at the contractor's expense, a complete Title22 potable water test prior to tie-in.

Bacteria tests are valid for 30 days. If there is more than a 30 day lapse between a bacteria testand the applicable tie-in, the bacteria test must be repeated prior to performing the tie-in.

39

1-1.20 Water Main Connection Work

Upon completion of construction, final connection will be made by the Contractor underinspection by a Special Districts Representative, unless otherwise specified on the plans.The Contractor shall notify the District inspector 48 hours prior to individual mainline shutdownsrequired to facilitate a tie-in. The contractor shall schedule tie-in work with the Administrator orthe Deputy Administrator at (707) 263-0119. Tie-ins will not be scheduled until a written passingbacteria test has been received by Special Districts Administrator. All shutdowns and valveturning operations shall be performed by District personnel only. An inspector must be presentduring all tie-in operations. No tie-ins shall be performed without prior authorization of theAdministrator.

Contractors or parties who fail to keep field appointments shall be billed for scheduled SpecialDistricts crew waiting or standby time which was used and the contractor shall bear the costsincurred by Special Districts for notification of its customers for the subsequent appointment.

Work requests, which will involve Special Districts forces for more than 8 hours or an extensivenumber of District supplied parts, shall be requested a minimum of 7 calendar days in advance.If it is necessary to terminate service to any customer, the contractor shall make the request forsuch work an additional 72 hours (three additional working days for a total of five working daysadvance notice) in advance of the time such services are desired to allow the customersaffected to have a minimum 72 hour notice.

When installing a cut-in-tee that is larger than the existing pipe, the new assembly must beinstalled at the depth sufficient to allow the valve to remain below the subgrade of the streetwhich may necessitate lowering the existing pipe.

When a connection is required to an existing water pipe, the contractor shall provide allexcavation, shoring, backfill and trench resurfacing per County Standard 215. Where theconnection is to be a "hot tap", the contractor shall provide and install the tapping valve andsleeve, and any other hardware required and make the tap at the developer's expense.

When any joint on an existing water pipe is disturbed, that joint and any proposed hot tap 4" andlarger, shall be replaced with a "cut-in" tee. When a "cut-in" tee and valve(s) assembly isrequired on the plans, the contractor shall provide and install the entire assembly (includingvalves), and any other hardware necessary under Special Districts' inspection, and shall provideall other work and materials necessary to complete the installation to County Standards.

40

During the work, the Contractor shall exercise all necessary precautions to prevent the entranceof trench water or any other foreign material into the water main and shall conduct all operationsin accordance with the most stringent sanitation practices. The interior of all appurtenancesbeing installed shall be thoroughly swabbed with a strong. high test hypochlorite (HTH) solutionprior to installation.

Tie-in or cut-in tee connections to cast iron, PVC, or ductile iron pipes shall be made'withmechanical joint solid sleeves. Flexible connections shall only be used when connecting toasbestos cement pipe.

Pipe and fittings furnished for tie-ins shall be no smaller than the existing water main to whicheach tie-in is made.

1-1.21 Water System Component Reporting

The Contractor shall submit the material type, manufacturer and model number of all watersystem components to the District inspector prior to final testing.

1-1.22 Construction Water

Un-metered connections are not permitted to the County water system, including connectionsbypassing meter for testing onsite plumbing or for obtaining construction water.

When a subdivision water main has been accepted and tied-in the individual curb stops will belocked off with cable ties. Cutting off or tampering with the cable ties will constitute a straight tie-in connection. Such connections will be severed by Special Districts and will result in penaltiesincluding payment of fines and estimated water usage fees.

Construction water shall be obtained from the County water system only at the point(s)designated by the Administrator. A deposit for each meter will be required which is refundableupon removal of the meter by District forces, less any charges for water used.

Contractors are prohibited from operating gate valves or fire hydrants on the County'system.Use of water obtained from unmetered fire hydrants or other facilities is a violation of Countyordinance and State law. Use of construction water from sources other than the County WaterSystem must be approved by the Administrator.
