The water should be withdrawn from the treatment plant and not from fire hydrants or dead-end lines, etc. All water supply valves must be in good condition (i.e., not leaking)
Equipment: All valves must be maintained in good condition and not leaking. The tanker used to haul water must have documentation on its prior use and reconditioning, and must be clearly marked "Drinking Water Only." There shall be a covered opening of sufficient size to enable the inside of the tank to be cleaned and inspected. All the water contact surfaces shall be smooth, impervious and free of corrosion. Coatings must be non-toxic and of a type that will not flake off in the water. Only non-toxic coatings as described in the DW-42 Drinking Water Additives and System Components may be used on water contact surfaces. Water hoses must be rubber or plastic (if plastic, it must bear the NSFpw seal) and must be protected on the open end with a cap.
Tank: Tanks must be provided with a protected vent to prevent negative pressure backflow. The tank must contain a manhole large enough to allow the tank to be cleaned and inspected. The inside of the tank must be smooth and free of corrosion. Interior coatings must be non-toxic and approved by the Office of Environmental Health Services - Environmental Engineering Division
Operation: Three ounces of 5.25% bleach must be added to the tank for each 1,000 gallons water capacity prior to filling. The chlorine residual must be measured and recorded before delivery, and the total chlorine must be at least 1.0 ppm. The tank must be protected from contamination at all times, no openings should be exposed allowing contamination into the tank.
