When located wholly or partly below ground, such storage basins shall be of corrosion resistant materials.

B. [formerly paragraph 12:013-2] Cisterns used for potable water shall be provided with a rain water cut-off, suitable to deflect the first washings of the roof and prevent contamination of the water. Cisterns shall be tightly covered, and screened with 18-mesh wire screen.

C. [formerly paragraph 12:013-3 Vent Openings] Any vent, overflow, or water level control gauge provided on tanks or other structures containing water for any potable water supply shall be constructed so as to prevent the entrance of birds, insects, dust or other contaminating material. Openings or vents shall face downward and shall be not less than 2 feet above the floor of a pump room, the roof or cover of a tank, the ground surface or the surface of other water supply structures.

D. [formerly paragraph 12:013-4 Coatings] Paints or other materials used in the coating of the interior of cisterns, tanks or other containers in which potable water is processed or stored shall be nontoxic to humans and shall be of such composition that the palatability of the water stored or processed shall not be adversely affected. The "Standard for Coating Steel Water Storage Tanks" (AWWA D102-11) published by the American Water Works Association shall be complied with. Determination of acceptability of coatings for potable water applications by the U.S. Environmental Protection Agency may be considered evidence of compliance with this Subsection.
