A. General requirements. Every park shall have a water supply system capable of providing a sufficient supply of potable water under adequate pressure to water supply facilities for mobile homes, travel trailers, service buildings, sanitary stations, fire hydrants and other accessory facilities as required by this chapter for the well-being of park residents and for park maintenance. Such a system shall be designed, constructed and maintained in accordance with state and local laws and shall conform to the regulations of the authorities having jurisdiction. B. Source of supply. (1) Where a public water supply system is available, the park water supply system shall be connected thereto. (2) Where a public water supply source is not available, the park's source of water supply, including the construction, equipment and distribution system for withdrawing and distributing water, shall be approved by the Suffolk County Department of Health Services and other authorities having jurisdiction. (3) The water source shall be capable of producing an adequate volume of water to supply all mobile home and travel trailer lots in any park, but in no case shall such capacity be less than 150 gallons per space per day in any mobile home park, nor less than 100 gallons per space per day in any destination travel trailer park, nor less than 50 gallons per space per day in any overnight travel trailer park. C. Water storage facilities. All structures used for storing potable water in any park shall be watertight and so constructed and located as to protect the contents against pollution. Reservoirs shall be provided with watertight covers. All manholes and openings required for proper operation of water storage facilities shall be covered or screened to prevent the entrance of birds, insects, vermin and other contaminants. There shall be no direct drainage between a reservoir and any pipe conveying or liable to convey sewage or polluted water. D. Water distribution system.

Such piping shall not be interconnected or cross-connected with any drainage, venting or other system conveying nonpotable water. E. Individual space connections in mobile home parks. (1) Individual water service connections shall be provided at each mobile home and travel trailer space in mobile home parks. All water service connections shall be watertight and located at a safe distance from sanitary sewer connections. The minimum pipe size of connections shall be at least 1/2 inch. Outlets shall be so constructed as to be free of possible contamination from surface drainage and possible damage during installation of a mobile home or travel trailer. (2) 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 ground during freezing weather. F.
