Town of Cortlandville, NY Water

Service pipes will be required to be laid not less than five feet below the surface of the earth at any point to the inside of the foundation wall of the building into which the water service is introduced; and in case the final grade of the street or sidewalk has been officially determined and established, then the said service pipe shall be laid at a depth of not less than five feet below said established grade at all points, so that when the street and walk are graded, there shall be not less than a five-foot covering of earth over it at any point, and in no case shall a service pipe be laid in the same trench or within 10 feet horizontally of, or be located in, under or above, cesspools, septic tanks and septic tank drainage fields or seepage pits. Where such water supply pipe must cross the sewer line, the bottom of the water supply pipe within 10 feet of the crossing shall be at least 12 inches above the top of the sewer line. [New York State Building Code 902.8(A)].

At no time should a water service pipe be laid in the same trench or within five feet of a gas, steam, electrical or other conduit any part of the distance from the main pipe to the building. Service pipe shall not be laid any deeper than is approved by the Town Water Superintendent.

In the event that a building requesting a water service is built on a slab, said service shall enter the building at a depth of five feet and service shall be placed in a PVC conduit at least three times the diameter of the service coming in and the conduit shall not have any bends greater than 22°.

No pipe or fixtures connected with the mains of any Water District of the Town of Cortlandville shall be connected with pipes or fixtures supplied with water from any other source or with any apparatus which may endanger the quality of the District's water supply.

The Town Water Superintendent personally, and any person delegated by him for that purpose, must at all reasonable hours have access to all parts of any premises supplied with water or having water pipes therein, to examine pipes and fixtures the quantity of water used and the manner of use.

Whenever it is specified in these rules and regulations that notice is to be given, it must be in writing and on a blank form furnished by the Town, acting on behalf of any Water District, for that particular purpose.

§ 171-6 Meters.

The Town Board reserves the right to order a meter to be placed on any service pipe at the expense of the owner of premises whenever it is deemed expedient so to do, and thereafter to charge meter rates for water used. All water passing through a meter will be charged for, whether used or wasted. All such meters shall be purchased by the Town Board and paid for by the consumer at cost plus 10%.

In the case of a service which is or has been metered, no permission will be given for the use of water except through a meter.

The Town Board shall be reimbursed for any damage to a meter resulting from the carelessness of the owner, his agent or tenant, or from neglect of either of them to properly secure and protect the same, including any damage that may result from allowing said meter to become frozen, or to be injured by hot water or steam setting back from a boiler, and in case such payment is not made, the water shall be shut off to said premises without notice and will not be turned on again until all charges are paid.

The Town Board will keep all meters in repair and working order and within 3% accuracy.

When a meter is out of service for repair or fails to register accurately and during the time it is out for test or repair, the consumer's charge will be based upon an estimate in accordance with the amount used in a corresponding period of the previous year, unless more fixtures have been added or it is known that more water is used, and in such case an amount will be added for extra use.

The owner and tenant shall provide ready and convenient access to the meter so that it may frequently be read and examined by the Town Water Superintendent, his agents or employees or such persons as he may designate.

No meter shall be set or removed or distributed by any person, except by the Town Water Superintendent, his agents or employees or persons designated by him. Any violation of this rule shall subject the person violating the same to a penalty as provided in § 171-14.

The application must be verified by the applicant.

[Amended 8-5-1998 by L.L. No. 2-1998]

The forfeiture or suspension of recognition of any plumber operates as the forfeiture or suspension of recognition of any copartner or employee of such suspended plumber. Recognition issued to a plumbing firm becomes inoperative on the dissolution of said firm, and a new application must be filed for any party continuing the business of such firm.

Recognition becomes inoperative whenever the party or parties to whom it is issued no longer have a recognized place of business or shop.

No plumber shall allow his name to be used by any other person or party, either for the purpose of obtaining permits or doing work under his recognition. Recognition cannot be transferred.

The plumber designated and employed by the owner of the premises will be considered the agent of such owner while employed in the prosecution of the work or while introducing water into said premises, and will not be recognized in any sense as the agent of any Water District of the Town of Cortlandville. Neither any Water District nor the Town of Cortlandville shall be responsible for the acts of such plumber.

No plumber shall part with the possession of a key for turning off or on the water except to an agent or employee of the Town Board, and no person, unless especially authorized by the Town Board, shall have or hold such a key in his possession. Any violation of this provision shall subject the offender to a penalty as provided in § 171-14.

[Amended 8-5-1998 by L.L. No. 2-1998]

All plumbers shall within 48 hours after completing the work on any service pipe make a written report to the Town Board of all pipes attached or connected or disconnected by them or under their supervision.

The curb cock controlling any service shall not be opened or left open by the plumber or any other person after connecting said service at the curb or elsewhere, or after making any new extension or attachment so that the water may be supplied to such premises by said service, unless permit designates that curb cock is to be left open. Any person violating any provision of this rule will be subject to a penalty as provided in § 171-14, or a revocation of the plumber's recognition, or both.

[Amended 8-5-1998 by L.L. No. 2-1998]

Within one foot inside the basement wall of the building into which the service pipe extends, a separate stop shall be placed on each side of the meter, such stop to be of such material and pattern as the Town Water Superintendent may specify.

When trenches are opened for the laying of service pipes, such trenches shall be inspected by the Town Water Superintendent or his agent before the same are filled; and the plumber performing such work shall notify the Town Water Superintendent or his agent when the laying of service pipes is completed and the water turned on for test in order that such inspection may be made. The filling of a trench before inspection is made will subject the plumber to whom a permit is issued to a penalty as provided in § 171-14. Twenty-four hours' notice must be given prior to inspection.

[Amended 8-5-1998 by L.L. No. 2-1998]

Inspection of pipe before installation. All pipe and fittings shall be inspected by the Engineer before placement in the trench. Cracked, broken, warped, out-of-round, or otherwise defective pipe or fittings shall be rejected and culled out by the Engineer.

Installation.

Pipe and fittings shall be installed in the conditions outlined on the detailed contract drawings. When pipe cover material is specified, this material shall be tamped around and under the full barrel of the pipe. Unless otherwise specified on the drawings, minimum cover over the top of the pipe or fittings shall be five feet. During installation, the contractor shall prevent the entrance of all foreign material (such as dirt, water and stones) into the pipe.

On ductile iron pipe two serrated silicon bronze wedges shall be inserted in the bell, 180° apart at three o'clock and nine o'clock. Thrust blocking shall be installed at all elbows, tees, hydrants, plugs and caps with dimensions specified on the detailed drawings. Concrete blocking shall be poured against undisturbed soil. Steel tie-rod (3/4 inches in diameter) restraining hardware shall be used at fittings and valve clusters as shown on the contract drawings.

Copper water service pipe shall be installed under all roadways by a trenchless method. The trenchless method shall be accomplished by the use of a soil-displacement-type hammer. The boring tool shall provide an open hole of adequate diameter to allow itself to successfully pull through a 3 inch I.P.S., DR 17, PE 3408 polyethylene pipe casing. Copper water service pipe shall be installed in the casing without filling of the annular space.

Where copper service piping is installed by open-cut excavation, the pipe shall be bedded and covered with approved granular material with a maximum particle size of two inches, as shown on the detailed drawings.

Cleaning water mains. After the completion of the water main installation, all mains will be flushed with water to remove all dirt and stones which may have entered during construction. Pipes shall be flushed until the water runs clear.

(6)

Disinfection of water mains.

All water mains shall be disinfected in accordance with ANSI/AWWA Specification C601-B1-a, a copy of which can be furnished by the owner/engineer to the contractor upon his request.

After the main has been disinfected and flushed, three samples of water shall be tested for total coliform in a New York State Department of Health approved laboratory. If drinking water standards are not met, the disinfection procedure shall be repeated at no extra cost to the owner.

Hydrostatic testing of water mains. After backfilling, all pipe shall be subjected to a pressure test and a leakage test in accordance with AWWA Spec. C600, Section 4, as follows:

Pressure test. After the pipe has been laid, all newly laid pipe or any valved section thereof shall be subjected to a hydrostatic pressure of at least 1.5 times the working pressure at the point of testing.

Test pressure restrictions. Test pressures shall:

Not be less than 1.25 times the working pressure at the highest point along the test section.

Not exceed pipe or thrust-restraint design pressures.

Be of at least two-hour duration.

Not vary by more than + or - 5 psi (0.35 Bar) for the duration of the test.

(e)

Not exceed twice the rated pressure of the valves or hydrants when the pressure boundary of the test section includes closed gate valves or hydrants.

NOTE: Valves shall not be operated in either direction at differential pressure exceeding the rated pressure.

(f)

Not exceed the rated pressure of the valves when the pressure boundary of the test section includes closed, resilient-seated gate valves or butterfly valves.

Pressurization. Each valved section of pipe shall be filled with water slowly, and the specified test pressure, based on the elevation of the lowest point of the line or section under test and corrected to the elevation of the test gauge, shall be applied by means of a pump connected to the pipe in a manner satisfactory to the owner. Valves shall not be operated in either the opening or closing direction at differential pressures above the rated pressure. It is good practice to allow the system to stabilize at the test pressure before conducting the leakage test.

Air removal. Before applying the specified test pressure, air shall be expelled completely from the pipe, valves and hydrants. If permanent air vents are not located at all high points, the contractor shall install corporation cocks at such points so that the air can be expelled as the line is filled with water. After all the air has been expelled, the corporation cocks shall be closed and the test pressure applied. At the conclusion of the pressure test, the corporation cocks shall be removed and plugged, or left in place at the discretion of the owner.

Examination. Any exposed pipe, fittings, valves, hydrants and joints shall be examined carefully during the test. Any damage or defective pipe, fittings, valves or hydrants that are discovered following the pressure test shall be repaired or replaced with sound material, and the test shall be repeated until it is satisfactory to the owner.

Mains.

All mains, fittings, valves, hydrants shall have a minimum earth cover of 5.0 feet. All mains shall be installed on a uniform grade and at an elevation to conform to the connecting mains. Mains shall be interconnected where possible and dead ends, if unavoidable, shall not exceed 600 linear feet in length and be provided with a hydrant at the end.

Mains shall be installed on a bed of selected earth free from stones or in a bed of sand or fine crushed gravel, to provide uniform support the length of the pipe. All backfill around the pipes and for a height of 12 inches above the pipe shall be firmly tamped in place. The remainder of the trench may be tamped in layers or rolled and machine-tamped in place. Pipes shall not be embedded in clay or vegetable matter or similar materials.

All tees, fittings, plugs, pipe ends and hydrants shall be firmly supported by concrete thrust blocks of sufficient size to prevent separation of the joints or to prevent the pipe from shifting out of alignment. Size of thrust blocks shall be calculated by standard engineering design methods. All installed brass fittings that come in contact with potable water shall not be composed of lead.

Service pipes shall conform to ASTM B-88 Type K copper water tube. An eight-inch-radius loop shall be provided in the pipe at the connection of the service pipe to the main to provide flexibility. All service pipes shall have a brass corporation stop inserted in the main, a brass inverted key curb stop and drain with C.I. curb box at the right-of-way line and a brass ground key meter top and drain at the point where the service line ends and the meter is installed.

Leakage tests.

The leakage test shall be conducted concurrently with the pressure test.

Definition. "Leakage" shall be defined as the quantity of water that must be supplied into the newly laid pipe, or any valved section thereof, to maintain pressure within five pounds per square inch (0.35 Bar) of the specified test pressure after the air in the pipeline has been expelled and the pipe has been filled with water. Leakage shall not be measured by a drop in pressure in a test section over a period of time.

Allowable leakage.

No pipe installation will be accepted if the leakage is greater than that determined by the following formula:

		SDP ^1/2
	L =
		133,200

Where:
	L =	The allowable leakage, in gallons per hour
	S =	The length of pipe tested, in feet
	D =	The nominal diameter of the pipe, in inches.
	P =	The average test pressure during the leakage test, in pounds per square inch gauge.

These formulas are based on an allowable leakage of 11.65 gallons per day, per mile, per inch nominal diameter at a pressure of 150 pounds per square inch. When testing against closed metal-seated valves, an additional leakage per closed valve of 0.0078 gal/h/mm) of nominal valve size shall be allowed. When hydrants are in the test section, the test shall be made against the closed hydrant.

Acceptance of installation. Acceptance shall be determined on the basis of allowable leakage. If any test of pipe laid discloses leakage greater than that specified above, the contractor shall, at his own expense, locate and make repairs as necessary until the leakage is within the specified allowance. All visible leaks are to be repaired regardless of the amount of leakage.

The tests shall be observed and approved by the Town Water Superintendent before acceptance and connection of the mains to the Water District system.

Disinfection.

The system shall be disinfected and sterilized and be satisfactory in all respects to the Departments of Health of the State of New York and Cortland County and all water departments supplying water to the Water District. Samples shall be submitted as required by such agencies and written approval shall be submitted as proof of satisfactory disinfection. In addition to the foregoing, the treated water shall produce a residual of 10 parts per million of chlorine after a twenty-four-hour retention period.

The disinfection of the system shall not take place until just prior to connection of the system to the Water District or mains. Samples of the water in the main shall be taken over a full two days and tested and approved.
