Section XII-329 - Construction and Installation of Pumps [formerly paragraph 12:009-1]

A. All water pumps shall be so constructed and installed as to prevent contamination of the water supply.

1. [formerly paragraph 12:009-2 Hand Pump Head and Base] Every hand-operated pump shall have the pump head closed by a stuffing box or other suitable device to exclude contamination from the water chamber. The pump base shall be of solid one-piece recessed type of sufficient diameter and depth to admit the well casing as hereinafter provided. The top of the casing or sleeve of every well, equipped with such a pump, shall project into the base of the pump at least 1 inch above the bottom thereof and shall extend 12 inches above the level of the platform, well cover, or pump room floor on which the pump rests. The pump shall be fastened to the casing or sleeve. The pumps shall be of the self-priming type.

2. [formerly paragraph 12:009-3 Power Pump] Where pumps or pump motors are placed directly over the well, the pump or motor shall be supported on a base provided therefor. The well casing shall not be used to support pump or motor. This requirement shall not apply to submersible pumps/motors and single-pipe jet pumps/motors. The pump or motor housing shall have a solid watertight metal base without openings to form a cover for the well, recessed to admit the well casing or pump suction. The well casing or pump suction shall project into the base at least 1 inch above the bottom thereof, and at least 1 inch above the level of the foundation on which the pump rests. The well casing shall project at least 12 inches above ground level or the top of the floor.

3. [formerly paragraph 12:009-4] Where power pumps are not placed directly over the well, the well casing shall extend at least 12 inches above the floor of the pump house. In flood-prone areas the top of the casing shall extend at least 2 feet above the highest flood level which may have occurred in a 10-year period, but in no case less than 2 feet above the ground surface. The annular space between the well casing and the suction pipe shall be closed by a sanitary well seal to prevent the entrance of contamination.

4. [formerly paragraph 12:009-5 Well, Pump, Valve, and Pipe Pits] No well head, well casing, pump, or pumping machinery shall be located in any pit, room, or space extending below ground level, or in any room or space above the ground which is walled in or otherwise enclosed so that it does not have drainage by gravity to the surface of the ground, except in accordance with design approved by the state health officer, provided, that this shall not apply to a dug well properly constructed as herein prescribed.

5. [formerly paragraph 12:009-6 Pump House] All pump houses shall be properly constructed to prevent flooding, and shall be provided with floor drainage.

6. [formerly paragraph 12:009-7 Lubrication of Pump Bearings] Well pump bearings shall be lubricated with oil of a safe, sanitary quality or potable water.

7. [formerly paragraph 12:009-8 Priming of Power Pumps] Power pumps requiring priming shall be primed only with potable water.

8. [formerly paragraph 12:009-9 Priming of Hand Pumps] Hand-operated pumps shall have cylinders submerged so that priming shall not be necessary. No pail and rope, bailer, or chain-bucket systems shall be used.

9. [formerly paragraph 12:009-10 Airlift Systems] The air compressor and appurtenances for any airlift system or mechanical aerating apparatus used in connection with a potable ground water supply, shall be installed and operated in accordance with plans and specifications that have been approved as part of a permit issued by the state health officer.
