[HISTORY: Adopted by the Board of Supervisors of the Township of Upper Uwchlan as indicated in article histories. Amendments noted where applicable.]
[Adopted 10-17-1988 by Ord. No. 88-04]
The purpose of the provisions of this article are to:
Insure that each dwelling unit and each commercial or industrial building in all subdivisions and land developments hereafter granted approval shall have an adequate supply of potable water for domestic use; and
Insure that each unit or building shall have an adequate supply of water for purposes of fire protection; and
Insure that in each case where water is to be supplied to a subdivision or land development by means of a public water supply system, such system meets minimum standards controlling water storage and production capabilities for domestic and fire use for the protection of the health, safety and welfare of all Township residents.
All land developments within the franchise area of a public water company and all of that area within 1,500 feet of a water supply main operated by a water company in Upper Uwchlan Township should be serviced by public water which shall be provided by a public utility organized and operating under the laws of the Commonwealth of Pennsylvania or by a municipal authority or other municipal corporation organized and operating under the laws of the Commonwealth of Pennsylvania.
If the applicant for subdivision or land development approval proposes that the subdivision or land development be served by public water, the applicant shall submit, upon submission of the preliminary plan, seven copies of documentation which shall be designated as "proposed public water supply study" which shall contain the following information:
The name, address and telephone number of the proposed public water supplier (company, water company or public utility) proposed by the applicant to supply water to the subdivision or land development.
A complete description of the source of the water supply, the quantity and quality of the water available from that source and the capacity of all reservoirs and their locations.
If wells are to be utilized as part of the supply system, the number of wells, pumping capacity of each well, the number of hours per day that each well pump operates, diameter of well casing, draw-down rated capacity of each well, and the maximum sustained yield from the well test together with a copy of the well test data.
Size of the water mains to be utilized in the proposed subdivision or land development, size of all water mains on the system proposed to service the subdivision or land development, the number of existing fire hydrants on the system and the number of fire hydrants proposed for the new subdivision or land development.
The number of residential customers on the existing system proposed to service the subdivision or land development and the number of gallons required to service the existing system as of the supplier's last billing.
The number of commercial and industrial customers on the existing system proposed to service the subdivision or land development and the number of gallons required to service the system as of the supplier's last billing.
Fire hydrant test results made by the Insurance Services Office of Pennsylvania for the existing system proposed to service the subdivision or land development. In the event the system has been expanded to service additional customers since the date of the last test, applicant shall set forth the number of new customers, designating them as residential, commercial or industrial, as applicable, additional gallonage required to service those customers and the number of additional hydrants installed on the system.
A description of the service area of the public water supplier, and, if regulated by the Public Utilities Commission of the Commonwealth of Pennsylvania, whether the proposed subdivision or land development is within the supplier's approved franchised area. Public Utility Commission approval to a public water company to extend any franchise area to include the proposed subdivision or land development shall be a condition precedent to subdivision or land development approval.
The proposed public water supply study submitted by the applicant shall be reviewed by the Township Engineer in conjunction with the subdivision or land development application process and he shall make a recommendation to the Board of Supervisors with respect to the applicant's compliance with the section. The applicant must bear the cost of Township engineering review and report and agrees to pay the cost thereof by submission to the Township of a subdivision or land development application. Submission by the applicant of a complete "proposed public water supply study" is essential and no subdivision or land development application, whether preliminary or final, shall be granted approval without such submission.
In all subdivisions and land developments served by public water, the following water pressure and gallonage requirements shall apply:
A minimum domestic pressure of 30 pounds per square inch shall be provided at each house to be connected to the water main. The system to which the residential unit is connected shall have sufficient capacity to supply a minimum of 300 gallons of water per residential unit per day within the subdivision or land development.
For purposes of fire protection in residential districts, the system shall be demonstrably capable of providing fire flow water requirements for a minimum duration of two hours of not less than 500 gallons per minute at residual pressures of 20 pounds per square inch or more as required for ISO certification.
Commercial or industrial use.
A minimum pressure of 30 pounds per square inch shall be provided at each commercial or industrial building connected to the water supply main. When a builder wishes to connect to a public water system, a study will be made to determine if there is adequate water to supply system to supply the building and use.
For purposes of fire protection in commercial and industrial districts, 1,000 GPM at 20 psi residual pressure is required or as required for ISO certification.
No subdivision or land development application proposing a public water supply system shall be granted preliminary or final approval unless the applicant demonstrates by a fair preponderance of the credible evidence full compliance with the provisions of this article.
Water mains shall be constructed of the cement-lined, ductile iron, minimum class 52 pipe or as approved by the Township Engineer. No extension of water mains shall be permitted for a pipe having a diameter of less than six inches.
All pipe shall have a minimum cover of three feet six inches from grade to the crown of pipe.
Generally, water mains shall be so designed as to form a loop system to enhance the continual supply of fresh water. When dead ends occur on new mains, they shall all be closed with cast iron plugs and caps, with a blowoff valve, with a concrete anchor, or fire hydrant.
Mains shall be drained through drainage branches or blowoffs to dry wells from which the water can be pumped. Drainage branches, blowoffs, air vents, and appurtenances shall be provided with valves.
Blowoffs shall not be connected to any sewer, or submerged in any manner that will permit back siphonage in the distribution system. All blowoffs should be located out of paving.
Valves in water mains shall, where possible, be located on the street property lines extended. A cast iron valve box or a masonry pit shall be provided for every valve which has no gearing or mechanism, or for which the gearing or operating mechanism is fully protected with a cast iron grease case. A masonry valve pit shall be provided for every valve which has exposed gearing or operating mechanisms.
Manholes shall be constructed of brick or concrete, with cast iron frames and covers or as approved by the Township Engineer.
Fire hydrants shall be provided as an integral part of any public water system. They shall be located no farther than 600 feet apart as measured within the right-of-way. Each hydrant shall be connected to the main with a minimum of a six-inch ductile iron branch controlled by a minimum of an independent six-inch gate valve.
Hydrants shall be located in a manner to provide complete accessibility and so that the possibility of damage from vehicles or injury to pedestrians will be minimized. When placed behind the curb, the hydrant barrel shall be set so that no portion of the pumper or nozzle cap will be less than 24 inches from the gutter face of the curb. When set in the lawn space between the curb and the property line, no portion of the hydrant or nozzle cap shall be within six inches of the sidewalk.
All hydrant connections shall be reviewed by the fire company having jurisdiction with a favorable recommendation by the chief of said fire company being required.
