A.
General requirements. An adequate supply of potable water
shall be provided for mobile homes, service buildings and other accessory
facilities as required by this chapter. Where a public water supply system
of satisfactory quantity, quality and pressure is available, connection shall
be made thereto, and its supply shall be used exclusively. Where a satisfactory
public water supply system is not available, the development of a private
water supply system shall be approved by the Department of Environmental Resources
and the Allegheny County Health Department or other authorities having jurisdiction.
B.
Source of supply. An approved water supply shall be the
source of the water in each mobile home park and the supply, pressure and
distribution system shall be sufficient to sustain and operate the facilities
and equipment of the Township's fire protection system.
C.
Water supply shall be in accordance with the requirements
of the Department of Environmental Resources and the Allegheny County Health
Department.
All water storage reservoirs shall be covered, watertight and constructed
of impervious material. Overflows and vents of such reservoirs shall be effectively
screened. Manholes shall be constructed with overlapping covers, so as to
prevent the entrance of contaminated material. Reservoir overflow pipes shall
discharge through an acceptable air gap.
A.
All water piping, fixtures and other equipment shall
be constructed and maintained in accordance with state and local regulations.
B.
The water piping system shall not be connected with nonpotable
or questionable water supplies and shall be protected against the hazards
of backflow or backsiphonage.
C.
The system shall be so designed and maintained as to
provide a pressure of not less than 40 pounds per square inch, under normal
operating conditions, at service buildings and other locations requiring potable
water supply.
A.
Individual water riser pipes shall be located within
the confined area of the mobile home stand at a point where the water connection
will approximate a vertical position, thereby ensuring the shortest possible
water connection and decreasing susceptibility to water pipe freezing.
B.
The water riser pipe shall have a minimum inside diameter
of 1/2 inch and shall terminate at least four inches above the ground surface.
The water outlet shall be provided with a cap when a mobile home does not
occupy the lot.
C.
Adequate provisions shall be made to prevent freezing
of service lines, valves and riser pipes and to protect risers from heaving
and thawing actions of the ground during freezing weather. Surface drainage
shall be diverted from the location of the riser pipe.
D.
A shutoff valve below the frostline shall be provided
near the water riser pipe on each mobile home lot. Underground stop-and-waste
valves are prohibited unless their type of manufacturer and their method of
installation are approved.
