Extension Agreement:

When the customer desires a water main to be extended to furnish water service to any property for residential, commercial or industrial use, the customer (applicant) shall make a formal application and deposit with BPU an amount equal to the estimated cost of such connection, improvements or extension of the water distribution system, and shall sign and execute an agreement in a form satisfactory to BPU. If all work set forth in this agreement has not been completed within a two (2) year period, BPU may terminate the agreement or require an amendment including any increase in the initial deposit to offset any increase in construction cost.

BPU has two types of main extension agreements:

Plan A is for extensions made interior to the development. Water main extension costs are not refundable.

Plan B is for extensions exterior to the development. The initial cost of the extension shall be borne by the applicant. However, acreage charges shall be collected by the BPU from other property owners within the Benefit Area as water service is provided. These acreage charges are refunded to the customer who paid for the original extension. The acreage charge collected from other property owners will be proportional to the property area compared to the benefit area. Acreage charges shall not apply if the Board has an existing water main adjacent to the property. Acreage charges and customer refunds are discontinued after ten years.

Specifications:

The applicant shall pay an Engineering Design Services Fee as determined by the Board. The BPU’s Civil Engineering Department will prepare the water main design and estimated costs for all new developments. A BPU selected contractor will provide the water main installation.

The applicant shall submit a plat plan that has been approved by the Unified Government along with plan and profile drawings 90 days prior to the desired date for commencement of water main construction in the proposed development, showing streets, sanitary sewers, storm sewers, subsurface (rock) data or rock borings, sidewalks and the number and type of proposed structures. All data shall be submitted digitally in AutoCad dwg format. In an effort to respond in a timely manner to main extension requests, digital drawings will not include X-ref’s or Z-coordinates. The original design and estimated costs for water main extensions will be based on the plans submitted and any revision of those plans. Revisions that materially affect the original design and estimated costs may require an addendum to the original agreement or execution of a new agreement.

The length of the requested extension shall be that distance from the nearest existing distribution main of adequate capacity to the farthest point on the property being served or the last lot being served, as measured along the center line of existing and proposed street rights-of-way, unless a lesser distance shall be determined adequate by BPU.

The diameter and material of the main to be installed shall be determined by BPU, based upon a consideration of the following factors:

• a) Provisions of adequate service to prospective customers.
• b) Possible and contemplated future extensions of the main to be installed.
• c) Fire protection needs existing or anticipated in the area to be served.

If BPU desires to make the extension with pipe of a larger diameter than that reasonably required to serve the area to which the main is being extended, the additional cost for the larger diameter main shall be borne by BPU.

Estimated Cost:

The total estimated cost of the proposed water main extension will be prepared by BPU and the applicant shall receive one copy. The estimate shall include the cost of easements, pipe, fittings, valves, fire hydrants, rock excavation, miscellaneous material, labor, supervision, inspection, engineering, insurance, accounting, taxes, permits, construction equipment and tools, restoration of rights-of-way and overhead expenses. If the applicant fails to submit subsurface (rock) data or rock borings, the cost estimate will be prepared using ten percent (10%) solid rock, fifteen percent (15%) machine rock and seventy-five percent (75%) common soil excavation.

Upon completion of the water main extension, all costs will be determined. If the actual cost is less than the estimated cost, a refund of the difference shall be made to the applicant. If the actual cost is greater than the estimated cost, the applicant shall make an additional payment to BPU.

Construction:

After execution of the Agreement, BPU will attempt to construct the water main extension at a time more desirable to the applicant, however, BPU should be allowed a minimum of twelve (12) weeks from date of application to schedule its contractor for this work.

BPU’s Contractor shall furnish all labor, equipment, tools and material necessary for the extension of the water main. All equipment, materials, construction methods and tools shall comply with applicable code of local, state and federal authorities. All work in constructing the extension shall be subject to inspection and approval by BPU to ensure that such construction is in strict compliance with the construction specifications, drawings and plans.

Maintenance of the water main extension and appurtenances, street crossings and surface areas is BPU’s responsibility.

Special Conditions:

Whenever water main extensions are installed in other than dedicated public rights-of- way, the applicant shall execute and convey, without cost to BPU, all easements necessary to construct and maintain the water main extension specified herein, prior to the installation of the water main.

The applicant shall provide line, grade stakes, and complete grading along the alignment of the main to within one-foot (1′) of the final grade prior to the installation of the water main.

Interest on Deposits:

BPU will pay no interest on the applicant’s deposit or on any unrefunded balances.

Title of Extension:

The full title, ownership and right of exclusive possession to all water mains installed under these rules shall be and remain the property of BPU, unless otherwise specifically stated.

Right to Further Extend:

BPU reserves the right to further extend the water mains from and beyond each water main extension made under these rules.

Execution of Agreements:

Only the General Manager shall have the authority to approve and execute Water Main Extension Petitions and Agreements on behalf of the BPU. The General Manager has the right to negotiate with the applicant the terms and conditions for executed petitions and agreements; provided, that such developments contain at least 250 homes to be built in a single subdivision over a three (3) year period.

Cross-connections Prohibited:

No water service connection shall be installed or maintained by the Board of Public Utilities (Board) unless the water service is protected as required by the laws and regulations of the Kansas Department of Health and Environment, the Kansas Statutes Pertaining to Public Water Supply, K.S.A. 65-163a, 65-171y, Kansas City, Kansas Ordinance No. 65696 for the Control of backflow and Cross-Connections, and the Board’s Cross-connection control Policy.

A cross-connection shall be defined as any physical arrangement whereby a public or semi-public potable water supply system is connected directly or indirectly to any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture or other device that may contain contaminated water, sewage or other substance capable of spreading contamination into the potable water supply as a result of backflow.

Backflow Prevention Required:

An approved backflow prevention method shall be utilized or installed on every water service to a customer’s water system when the Board determines the public potable water supply may be subject to contamination, pollution or other deterioration in sanitary quality by conditions within the customer’s water system.

The backflow prevention method to be utilized or installed shall be determined by the Board. The method required by the Board shall be sufficient to protect against the potential degree of hazard, as determined by the Board, to the public potable water supply from the customer’s water system.

Hazard Potential:

The hazard to the public potable water supply from a customer’s water supply system shall be determined by using the following factors:

Health: The term “health hazard” shall mean an actual or potential threat of contamination of a physical or toxic nature to the public or the consumer’s potable water supply that would be a danger to the health and well-being of the consumer.

Plumbing: The term “plumbing hazard” shall mean an internal or plumbing type cross-connection in a consumer’s potable water system that may be either a pollution or a contamination type hazard. This includes but is not limited to cross-connections to toilets, sinks, lavatories, wash trays, domestic washing machines and lawn sprinkling systems. Plumbing type cross-connections can be located in many types of structures including homes, apartment houses, hotels, and commercial or industrial establishments.

System: The term “system hazard” shall mean an actual or potential threat of severe damage to the physical properties of the public or the consumer’s potable water system, or of a pollution contamination which would have an effect on the quality of the potable water in the system.

Containment: The term “containment” shall mean a method of backflow prevention which requires the installation of backflow prevention assemblies to protect the public water main supply from a building/premise water service supply and is governed by the Board of Public Utilities.

Isolation: The term “Isolation” shall mean a method of backflow prevention which requires the installation of a backflow prevention assembly at the cross-connection within a building or premise beyond the containment assembly and jurisdiction resides within the building and plumbing codes that have been adopted by the governing agency.

Approved Backflow Prevention Methods:

A backflow prevention method shall be any assembly or other means (approved by the Board) designed to prevent backflow.

A backflow prevention method may be approved by the Board if it has received the approval of the Foundation for Cross-Connection Control and Hydraulic Research of the University of Southern California, and or other approval agencies acceptable to the Board.

The Board shall maintain a list of approved backflow prevention assemblies, by type and manufacturer. The list shall, upon request, be furnished to any customer required to install a backflow prevention assembly.

Backflow Prevention Method Required for Specific Activities:

The Board shall maintain a list of backflow prevention methods required for specific activities or conditions. The list shall, upon request, be furnished to any customer required to install a backflow assembly.

When two or more of the activities are conducted, or conditions exist, on the same premises and served by the same water service, the most restrictive backflow prevention method shall be required to be utilized or installed in compliance with the standard specifications adopted by the Board.

Backflow Assembly Installation requirements – Location:

Required backflow prevention assemblies shall be installed by the customer, at the customer’s expense and in compliance with the standards and specifications adopted by the Board. The assembly shall have a diameter at least equal to the diameter of the water service connection.

The assembly shall be in an accessible location approved by the Board. A reduced pressure principle assembly, reduced pressure principle detector assembly and pressure vacuum breaker assembly must be installed above grade and provided with frost protection where necessary. A double check valve assembly or a double check detector assembly shall be installed in a pit according to BPU specifications.

When a customer desires a continuous water supply, two or more backflow prevention assemblies shall be installed parallel to one another on the service connection to allow a continuous water supply during testing of the backflow prevention assemblies. When backflow prevention assemblies are installed parallel to one another, the sum of the cross-sectional areas of the assemblies shall be at least equal to the cross-sectional area(s) of the service connection.

Installation of Backflow Prevention Assemblies for Fire Sprinkler Systems:

Backflow prevention assembly required for a water service supplying water only to a fire sprinkler system shall be installed horizontally on the water service in compliance with the standard specifications adopted by the Board.

When a customer desires a continuous water supply, two or more backflow prevention assemblies shall be installed parallel to one another on the water service to allow a continuous water supply during testing of the backflow prevention assemblies. When backflow prevention assemblies are installed parallel to one another, the sum of the cross-sectional areas of the assemblies shall be at least equal to the cross-sectional area(s) of the service connection.

Inspections:

Customers shall permit inspection of the water service during regular business hours upon request by the Board. Inspections shall be performed by authorized personnel of the Board, or its authorized agents. The inspection shall be conducted to determine whether any cross-connection or other hazard potentials exist and to determine compliance with this article.

Test – Maintenance – Records:

Initial testing shall be performed by a certified tester with the results sent to the Board of Public Utilities on a BPU approved form.

It shall be the customer’s responsibility to have the backflow prevention assembly tested and serviced annually by a certified tester. If the testing reveals the assembly to be defective or in unsatisfactory operating condition, the customer shall have the certified tester or repair technician perform any necessary repairs, which will return the assembly to satisfactory operating condition. After repair, retesting shall be performed by the certified tester and the results shall be sent to the Board of Public Utilities on a BPU approved form.

If the Board or the customer discovers, during the interim period between tests, that an assembly is defective, the customer shall have a certified tester or repair technician perform any necessary repairs, including replacement of the assembly, if necessary, which will return the assembly to satisfactory operating condition. After repair, retesting shall be performed by the certified tester and the results shall be sent to the Board of Public Utilities on a BPU approved form.

The annual testing of backflow prevention assemblies shall be performed by an individual certified to conduct such testing and approved by the Board of Public Utilities. BPU will keep a most current list of certified testers available from KDHE and it can be found in Appendix

The customer shall submit records on forms approved by the Board, of the results of all tests, servicing, repairs or replacement of the backflow prevention assembly.

Modification of Backflow Prevention Requirements:

If the Board determines, after inspection of the customer’s system, that a backflow prevention method less restrictive than that required in Section 12.05 will provide adequate protection of the public potable water supply, the Board may modify the requirements of Section 12.05 for said installation.

Discontinuance of Water Service – Notice:

If the Board discovers that a customer has not installed a required backflow prevention device or that a backflow prevention device has been improperly tested or maintained, bypassed or removed, or that an unprotected cross-connection exists in the customer’s water system, the water service to that service connection may be disconnected if the situation is not remedied within the time specified in the notice sent to the customer as required by this section. The service shall not be restored until the condition is remedied.

Water service to a fire sprinkler system shall not be subject to disconnection under this section. If a situation, which would otherwise result in discontinuance of water service in Section 7.11 – above, is not remedied within the time provided in the notice sent to the customer, the Board will notify the City Building Department and the City-County Health Department of this violation.

Prior to disconnecting any water service because a condition set forth in Section 7.11 – exists, the Board shall send a notice to the customer describing the condition and notifying the customer the condition must be remedied within thirty (30) days after mailing of the notice. If such condition is not remedied within said thirty (30) day period, the Board shall send a second notice, by certified mail, to the customer notifying the customer that water service will be disconnected in fifteen (15) days if the condition is not remedied within such time period.

The Board may disconnect, without notice, water service to any customer when the Board discovers that the customer’s water system is contaminating the public potable water supply.

Retroactive Application:

The provisions of this regulation shall apply to all new water customers. The need for backflow prevention for existing customers will be established based on the degree of hazard determined by inspection of the customer’s facilities by the Board or its authorized agent. This policy recognizes that the degree of hazard from a residential service connection is minimal and that the implementation activity of the Board of Public Utilities’ Cross-Connection Control Program will be concentrated in and directed towards industrial and commercial service connections representing a higher degree of hazard.

Backflow prevention assemblies installed prior to enactment of this regulation, and which do not comply with the requirements set forth in this regulation, shall be replaced with assemblies which comply with the standard set forth herein.

Plan Review:

All backflow prevention assemblies which will be installed shall be shown and specified on all required building, engineering and architectural plans. Board approval of the intended assembly installation is required prior to the issuance of any water service extension permit.

Backflow Prevention Method Required for Specified Activities:

PASSED BY THE COUNCIL OF THE CITY OF KANSAS CITY, KANSAS THIS

16th DAY OF JANUARY 1992

Approved:
Joseph E. Steineger, Jr.
Mayor

Attest:

______________________________
City Clerk
Approved as to form:

______________________________

Mary Ann Neath
Assistant City Attorney

A. Basic Considerations:

1. Quantity and Pressure – Water distribution systems shall be designed, constructed, and operated to provide an adequate supply of water at a pressure of not less than 20 psi (140 kPa) at ground level at all points in the distribution system under all conditions of flow. The normal working pressure in the distribution system should be approximately 60 psi (410 kPa). Pressures in excess of 100 psi (690 kPa) may be necessary because of low elevations with high system pressures. Pressure reducing valves may be used to lower the pressure in these areas if required.

Distribution mains for municipalities should be sized to meet peak hourly use plus fire demand and RWD mains should be sized to handle peak hourly demand. In the absence of metered data, peak hourly demand can be assumed equal to twice the maximum daily demand or four times the average daily flow. Methods for estimating peak consumer demand are provided in the AWWA Manual of Water Supply Practices M22 Sizing Water Service Lines and Meters (29).

The minimum size of water mains for providing fire protection and serving fire hydrants shall be 6 in. (15 cm) in diameter. Larger size mains may be necessary to provide sufficient fire flow while maintaining the minimum residual pressure. When fire protection is to be provided, system designs shall be in accordance with the PWSS’s designated procedure for determining fire flow requirements. One of the more widely utilized methods for calculating fire flow requirements was developed by the Insurance Services Office, Inc. (30). This procedure, as well as other methods, are evaluated in the AWWA Manual of Water Supply Practices M31, Distribution Requirements for Fire Protection (31).

2. Quality – The safety and palability of potable water should not be degraded in any manner while flowing through the distribution system. KAR 28-15-13 establishes the quality requirements for drinking water and KAR 28-15-14 lists the monitoring requirements for the laboratory tests.

3. General Pipeline Location

• a. Use available data on topography, soil, geology, and climate.
• b. Tunneling should be considered only when it is economically justified and when there are no feasible alternate routes.
• c. Select shortest feasible route from intake to delivery.
• d. Make lines accessible for future construction and repairs.
• e. Avoid rough or difficult terrain.
• f. Special engineering evaluations should be given where disasters such as landslides, 100-year floods, or other hazards are likely to cause breakage or outage.

B. Protection Considerations:

1. Separation of Water Mains and Sewers:

• a. Gravity Sanitary Sewers – When potable water pipes and gravity sanitary sewers are laid parallel to each other, the horizontal distance between them shall be not less than 10-ft. (3.0 m). The distance shall be measured from edge to edge. The laying of water pipes and sanitary sewers shall be in separate trenches with undisturbed earth between them. In cases where it is not practical to maintain a 10-ft. (3.0 m) separation, KDHE will consider proposals providing equivalent protection by other methods on a case-by-case basis, if supported by data from the design engineer. Equivalent protection may require sanitary sewer construction with one of the following additional protective features: concrete encasement, vacuum sewers, or jointless pipe such as polyethylene or cured-in-place.When a water pipe and a sanitary sewer cross and the sewer is 2 ft. (0.6 m) or more (clear space) below the water pipe, no special requirements or limitations are provided herein. At all other crossings, the sanitary sewer is to be constructed of one of the following materials (or approved equal) and pressure tested to assure water tightness pursuant to Chapter VI of the KDHE Minimum Standards of Design of Water Pollution Control Facilities:Ductile iron pipe conforming to ASTM A536 or ANSI/AWWA C151/A21.51 with minimum thickness class 50, and gasketed, push-on, or mechanical joints in conformance with ANSI/AWWA C110/A21.10 or ANSI/AWWA C111/A21.11.PVC pipe conforming to ASTM D3034 with minimum wall thickness of SDR41, ASTM F679, ASTM F789, or ASTM F794, with gasketed push-on joints in conformance with ASTM D3212.Reinforced concrete pipe conforming to ASTM C76 with gasketed joints in conformance with ASTM C361 or ASTM C443.Joints in the sewer pipe shall be located as far as practical from the intersected water main.Where a water main is laid across or through an area where there is an existing sanitary sewer, which is not constructed of one of the above specified materials and is 2 ft. (0.6 m) or less below the water pipe, the existing sewer shall be encased in concrete with a minimum of 6 in (15 cm) thickness for a 10 ft. (3.0 m) distance on each side of the crossing or the crossed section of sewer replaced to meet the above specified construction requirements. KDHE will consider proposals providing equivalent protection by other means on a case-by-case basis, if supported by data from the design engineer.
• b. Sewer Connections – There are to be no physical connections between any parts of the potable water system with building sewers, sanitary sewers, or wastewater treatment facilities by means of which it would be possible for sewage, even under exceptional circumstances, to reach the wells, storage reservoirs, or distribution systems.
• c. Pressure Sewer Lines – When force mains run parallel to water lines, the separation distance shall be as far as practical, but at least a 10 ft. (3.0 m) horizontal separation shall be maintained. There shall be at least a 2-ft. (0.6 m) vertical separation at crossings with the water main crossing above the sewer force main. In cases where it is not practical to maintain the required vertical or horizontal separation distance between a water line and a sanitary sewer force main, KDHE will consider proposals providing equivalent protection by other methods on a case-by-case basis, if supported by data from the design engineer.
• d. Sewer Manholes – No water pipe shall pass through or come in contact with any part of a sewer manhole.
• e. Storm Sewers – The separation distance between a storm sewer (which is not a combined storm/sanitary sewer) and a water main should be based on geotechnical considerations. Required separation distances between water mains and combined storm/sanitary sewers are equivalent to those for water mains and gravity sanitary sewers.
• f. Drains – Underground drains from fire hydrants or valve pits should not be directly connected to sanitary or storm drains.

2. Separation of Water Mains and Other Pollution Sources – It is of utmost importance that potable water lines be protected from any source of pollution. The following shall pertain to instances where septic tanks, absorption fields, waste stabilization ponds, feedlots, or other sources of pollution are encountered.

• a. A minimum distance of 25-ft. (7.6 m) shall be maintained between all potable water lines and all septic tanks or waste stabilization ponds.
• b. Under no circumstances shall a water line extend through a septic tank absorption field or feedlot. All water lines shall be located a minimum of 25 ft. (7.6 m) from the farthest known extent of any sewage contamination. Under no condition will it be considered that encasement of the water main through an area of real or potential pollution would provide the protection needed to the water supply.

3. Cross Connections – There shall be no physical connection between the PWSS and any pipes, pumps, hydrants, tanks, or non-potable waters supplies whereby unsafe water or other contaminating materials may be discharged or drawn into the system. KDHE approval shall be obtained for interconnections between potable water supplies. KDHE does not approve of interconnections of RWD lines and individual or independent water supply sources such as home wells. Neither steam condensate nor cooling water from engine jacket or other heat exchange devices shall be returned to the potable water supply.

KSA 65-171g prohibits the contamination of water (and air) by sewage through direct connection or backsiphonage and KAR 28-15-18 (h) requires each PWSS to have a formal cross-connection prevention program. KDHE must approve the program used to accomplish the control. AWWA, USC, and USEPA have published cross-connection control manuals (32-34).

The water purveyor should be aware of any situation requiring inspection and/or reinspection necessary to detect hazardous conditions resulting from cross connections. If, in the opinion of the utility, effective measures consistent with the degree of hazard have not been taken the water purveyor should take such measures as deemed necessary to ensure that the PWSS is protected from contamination. Such action would include the installation of a backflow protection device consistent with the degree of hazard or discontinuance of the service.

4. Line Crossings – Special precautions should be taken to prevent possible damage to line crossings.

• a. Surface Water crossings – Surface water crossings, both over and under water, present special problems which should be discussed with KDHE before final plans are prepared. Where the ground has inadequate bearing capacity, pile supports, stringers, or other acceptable methods shall be used. Pipeline crossings of perennial streams having 50 or more square miles (130 km2) of drainage area above the proposed project site require a permit from DWR other than directionally-bored crossings or crossings consisting of pipelines non-obstructively attached to an existing bridging structure.
  • 1) Above-Water Crossings – The pipe shall be adequately supported, protected from damage and freezing, and accessible for repair or replacement.
  • 2) Underwater Crossings – Underground pipelines shall be buried a sufficient depth below streambeds to prevent exposure. On navigable streams, underground pipelines shall be buried at a minimum depth of 7-ft.(2.1 m) beneath the streambed. On all other streams, underground pipelines shall be buried at a minimum depth of 5-ft. (1.5 m) beneath the streambed.
• b. Railroad Crossings and Mains Near Tracks – Where a water main crosses under railroad tracks, all joints lying within 10-ft. (3.0 m) of the rails shall be either mechanical joints with rubber gaskets or pipe with bell joints. Also local requirements should be investigated. Some railroads require that the water main be enclosed in a culvert, tunnel, or conduit to reduce the effects of vibration, to provide drainage in case of leakage or rupture of the pipe, to reduce damage to the track, and to facilitate repairs.

5. Pressure – When static pressures exceed 100 psi (690 kPa), pressure reducing devices should be provided on mains in the distribution system or on individual house service lines.

6. Dead-Ends – Dead-ends should be minimized by looping of all mains. Where dead-end mains occur they should be provided with a fire hydrant if flow and pressure are sufficient, or with an approved flushing hydrant, or a blow-off for flushing purposes. Flushing devices should be sized to provide flows which will give a velocity of at least 2.5 ft./sec. (0.76 m/s) in the water main being flushed. No flushing device shall be connected directly to any sewer.

Where dead-end lines are necessary in the first stage of construction of a pipe system, the pipe layout should be designed for future additions and connections to provide for water circulation in the existing systems.

7. Repairs, Replacement and Extension of water Mains – The system shall be maintained so as to prevent its contamination during necessary repairs, replacements, or extensions of mains. When pressure in any part of the distribution system becomes abnormally low, customers in the area shall be notified of necessary protective health precautions.

8. Frost – The top of all water pipes should be at least 6 in (15 cm) below the maximum recorded depth of frost penetration in the area of installation. The minimum depth of water mains should be 3-ft. (0.9 m) from the ground surface to the top of the pipe.

9. Plastic Pipe – Plastic pipe intended for transport of potable water shall be evaluated and certified as safe for this purpose by a testing agency acceptable to KDHE. The evaluation should be in accordance with requirements for chemical extraction, taste, and odor, that are no less restrictive than those included in NSF Standard 14 (28). The seal or mark of the laboratory making the evaluation shall be included on the pipe.

10. Pressure and Leakage Test – Pressure and leakage tests shall be conducted on each newly installed water main in accordance with AWWA Standards or KDHE Procedures for Pressure and Leakage Testing of Mains (Appendix C). The allowable leakage shall not exceed that established by AWWA Standards or KDHE Procedures.

11. Thrust Blocks – All tees, bends, plugs, and hydrants shall be provided with reaction blocking, tie rods, or joints designed to prevent movement.

12. Valves – The systems shall be provided with sufficient valves to permit necessary repairs without undue interruption of service over any appreciable area. Blow-off connections to sewers or sewer manholes are not permitted.

13. Sanitary Precautions – Sanitary precautions shall be taken in laying new pipe, especially in preventing the introduction of foreign materials into the pipe. Water should be kept out of the trench where new pipe is laid and open ends shall be plugged or capped overnight to eliminate potential sources of contamination.

The selection of materials is critical for distribution piping in locations where there is likelihood that the pipe will be exposed to significant concentrations of pollutants comprised of low-molecular-weight petroleum products, organic solvents, or their vapors. Pipe materials such as polyethylene, polybutylene, polyvinyl chloride, and elastomers, such as those used in jointing gaskets and packing glands, may be subject to permeation by lower molecular weight organic solvents or petroleum products. If a water main must pass through such a contaminated area, materials impermeable to the particular contamination shall be used for pipe walls, jointing materials, etc. as certified by the manufacturer of the pipe.

Disinfection – All water shall be properly disinfected before it reaches the first (nearest) consumer on the distribution system. Water stored for prolonged periods in reservoirs may require re-disinfection upon re-entry to the system. New mains and repaired main sections shall be disinfected according to applicable AWWA Standards or KDHE Water Main Disinfection Procedures (Appendix D) before being placed in or returned to service. When connections are made to an existing system, the exposed pipe interiors should be wetted with a 500-mg/L chlorine solution before closure.

14. Deposits and Corrosion – Corrective water treatment should be practiced where excessive deposits of chemical precipitates or biological growths or where corrosion occurs in the mains. Disinfection will control biological growths and water stabilization should be used to control chemical precipitation and minimize pipe corrosion (see Section L on Stabilization).

Chemicals added to the water for corrosion control shall conform to the applicable AWWA Standards (4) and shall be approved by KDHE. The corrosive effects of finished water on non-ferrous metal pipe used for water service lines should be considered including possible toxicological effects upon consumers resulting from solution of the metals.

Water mains shall be protected from exterior corrosion in cinder cuts or in corrosive soils by use of selected material for backfield or by wrapping or coating the pipe exterior with protective material. A 10-point soil evaluation procedure for predicting conditions corrosive to underground piping is provided in AWWA Standard C105.

15. Plumbing – Water services and plumbing shall conform to relevant State and local plumbing codes.

C. Materials and Installation:

• 1. Used Pipe – Water mains that meet the above standards may reused but only after the pipe has been thoroughly cleaned and restored as much as possible to its original condition.
• 2. Joint Materials – Materials used in the joints of pipe shall meet applicable AWWA Standards (4). Mechanical joints or slip-on joints with rubber gaskets are preferred.
• 3. Valve, Air Relief and Blow-Off Chambers – At high points in water mains where air can accumulate, provision shall be made to remove the air by means of hydrants or air relief valves. Automatic air relief valves shall be used when flooding of the manhole or chamber may occur.The open end of an air relief pipe from automatic valves shall be extend to at least 1 ft. (0.3 m) above grade and provided with a screened, downward-facing elbow. The pipe from a manually operated valve should be extended to the top of the spit. Manual operation of automatic air relief valves shall be possible.Chambers or pits containing valves, blow-offs, meters, or other such appurtenances to a distribution system, shall not be connected directly to any storm drain or sanitary sewer, nor shall blow-offs or air relief valves be connected directly to any sewer. Such chambers or pits shall be drained to the surface of the ground where they are not subject to flooding by surface water, or to absorption pits underground.
• 4. Fire Hydrants – Due to a concern over freezing, only “dry-barrel” hydrants will be approved for installation and such hydrants shall comply with AWWA Standard C502. Hydrant drains shall not be connected to a sanitary sewer or storm sewer. Specifications for installation of hydrants may be found in the AWWA Manual of Water Supply Practices M17 Installation, Field Testing, and Maintenance of Fire Hydrants (35).Fire hydrants should be connected only to water mains adequately sized to carry fire flows, and located to permit flushing of all mains and in compliance with local fire code requirements. Generally, fire hydrants should be provided at each street intersection and at intermediate points between intersections. Generally, hydrant spacing may range from 350 to 600 ft (110 to 180 m) depending on the area being served and the design flow. Additional discussion on criteria for the location of hydrants can be found in the AWWA Manual of Water Supply Practices M31 Distribution Requirements for Fire Protection (31).
• 5. Installation of Mains – Installations should follow applicable AWWA Standards, AWWA Manuals of Water Supply Practices, and/or manufacturer’s recommended procedures. AWWA Standards include C600 for Installation of Ductile-Iron Water Mains and their Appurtenances. AWWA Manuals of Water Supply Practices include AWWA M23, PVC Pipe – Design and Installation and AWWA M11, Steel Pipe – A Guide for Design and Installation (36,37). Widely recognized industry guidelines for installation of PVC pipe are provided in the Handbook of PVC Pipe, by the Unibell PVC Pipe Assoc. (38). Similarly, for ductile iron pipe installation, the Ductile Iron Pipe Research Association publishes the Guide for the Installation of Ductile Iron Pipe (39).A continuous and uniform bedding should be provided in the trench for all buried pipe. Backfill material should be tamped in layers around the pipe and to a sufficient height above the pipe to adequately support and protect the pipe. Stone found in the trench should be removed for a depth of at least 6 in. (15 cm) below the bottom of the pipe.

D. System Design:

Field Studies – The hydraulic performance of existing tests. Such testing should cover all typical portions of the community, and if need be, they can be extended into every block. The results obtained will establish available pressures and systems is determined most directly and flow, and will reveal existing available pressures and flow, and will reveal existing deficiencies. This information can then be made the basis for hydraulic calculations of extensions, reinforcements, and new grid layouts. Following expeditiously by pressure surveys and hydrant-flow completion of system improvements, additional tests can be conducted to determine how completely the desired changes have been accomplished.

Computer Modeling – No matter how well or complete the field study is done, hydraulic investigations of extensions and new and existing pipe networks should be confirmed using available computer analysis programs. Guidelines for performing such an analysis can be found in the AWWA Manual of Water Supply Practices M32 Distribution Network Analysis for Water Utilities (40).

Valve Spacing – Valves should be placed in numbers and locations that allow control of the system consistent with cost limitations, convenience and minimization of possible sanitary hazards. Valves in smaller mains are typically more numerous than those in larger mains. In transmission lines, valve spacing is determined by operating requirements, and thus are a matter of individual design. Typical spacings are not more than 500-ft. (150 m) in commercial districts, 800-ft. (240 m) in other districts, and where customers are widely scattered or where future development is not expected, not more than one mile (1,600 m).

Valve sizing – Valve sizes are normally the same as the water main in which they are installed except that in mains 30 in. (75 cm) and larger, line valves are sometimes smaller than the main size.

Fire hydrants should have a bottom valve size of at least 5 in. (13cm), one 4.5 in. (11 cm) pumper nozzle, and two 2.5 in. (6.3 cm) nozzles. The hydrant lead shall be a minimum of 6 in. (15 cm) in diameter. Auxiliary valves shall be installed in all hydrant leads.

Blow-off valves are usually sized 6 in. (15 cm) for mains 6 to 16 in. (15 to 40 cm), and 8 in. (20 cm) for mains 20 in. (50 cm) and larger.

Valve Location – Valves are usually located on the extensions of the various street property lines involved. Where property lines are not involved, the valves should be placed so that they can be referenced with respect to certain obvious monuments. Valves should be readily accessible in the event of a main failure.

Branch mains connecting to larger primary or secondary feeders which cross under arterial highways or streets should be valved close to the larger main before the crossing.

Blow-off valves and fire-hydrant valves should be located as close to the connected main as possible.

Buried valves normally are contained in a conventional valve box assembly and do not require vaults.

Metering – Each service connection shall be metered. A routine testing program is needed to check the accuracy of all meters in the system. Inoperable or malfunctioning meters should be repaired or replaced. Abnormal quantities of water use should be investigated to insure that service connections are not leaking or broken, especially where geologic conditions may prevent detection of leaking by observation.

Master meters which measure water supplies to the distribution system should be checked periodically for accuracy. They may either over-register or under-register, and the percent of error reflects directly on distribution systems losses. The proper selection and installation of the master meter is important.

When planning an installation, attention should be given to providing enough straight pipe ahead of the meter to ensure maximum uniformity of flow and therefore, accurate registration. Provisions should be made for testing the meter in place without interruption of service by using a test plug and a comparative test meter.

Meters shall meet applicable AWWA Standards (4). Recommended practices for the selection, installation, testing, and maintenance of water meters are provided in the AWWA Manual of Water Supply Practices M6 Water Meters – Selection, Installation, Testing, and Maintenance (41).

7. Water Loading Stations – Water loading stations present special problems since the fill line may be used for filling both potable water vessels and other tanks or contaminated vessels. To prevent contamination of both the public supply and potable water vessels being filled. The following principles shall be met in the design of water loading stations:

• a. A backflow prevention assembly, device, or method shall be utilized to ensure that there is no backflow to the PWSS. Possible devices or methods include the design of a mandatory air gap between the receiving tank, vessel, or container and the discharge end of the potable water supply pipeline not less than 2 times the diameter of the spout opening, or the installation of an backflow prevention or vacuum breaker assembly that meets KDHE requirements.
• The piping arrangement shall prevent contamination being transferred from a hauling vessel to others subsequently using the station.
• Hoses shall not be contaminated by contact with the ground.
