§ 37-125. Pump installation.

(a)

Generally. All pumps and pumping equipment shall be installed in conformity with the following provisions:

(1)

All power-driven pumps located over the wells shall be installed at an elevation of one (1) foot above any known floodwater level.

(2)

Where the pump unit is not located over the well and the pump delivery or suction pipe emerges from the top thereof, a watertight expanding or equivalent well seal shall be provided between the well casing piping.

(3)

The suction line and/or return line from the well to the pump shall pitch toward the well and shall contain no loops or high points. Suction pipes and/or return pipes forty (40) feet or more in length shall be increased to the next pipe size. Union or slip coupling shall be installed at the well and just before the pump and tank.

(4)

A pressure switch and pressure gauge, check valves and other apparatus shall be included to make a complete system. The pressure switch setting shall be 40/60.

(5)

An air volume control or other means of adding air to the tank shall be provided. A float in tank or similar device may be used.

(6)

Pump and tank shall be installed so as to be reasonably accessible for repair.

(b)

Materials prohibited. The following materials are prohibited on installations coming under this section:

(1)

No material shall be used in the well and pump installation that will result in the delivered water being toxic or having an objectionable odor or taste. All metallic and nonmetallic materials shall have sufficient structural strength and other properties to accomplish the purpose for which installed. Plastic pipe shall not be used, unless bearing the approval of the National Sanitation Foundation (NSF) and unless it has the physical properties to withstand the torque and load to which it will be subjected.

(2)

No sprinkler systems or other connections shall be made into a public or domestic water supply unless the materials used conform with the county and state board of health regulations for potable water. All plastic pipe shall bear the seal of the National Sanitation Foundation (NSF).

(c)

Pump house. If a pump house is constructed it shall be constructed of block, galvanized steel, wood, or any material that is approved by the building official, with proper ventilation for the pump. The houses shall be removable or have a removable top or hatch directly over the pump, permitting access to the pump for maintenance and repair. The pump house floor shall be of watertight concrete construction and shall slope uniformly away in all directions from the well casing or pump sleeve. Design of the pump house shall be approved by the building inspector. If a pump delivering potable water is provided with a tank, the tanks shall be so designed and installed as to prevent entrance of pollutants. The oil reservoir of the pump shall be constructed to protect the water from the entrance of pollutants. The lubrication system shall be designed and installed to minimize leakage of the oil into the water.
