CUC water division manager Mariano Iglecias said many water system customers on Saipan have their own tanks to catch rain water.
The tank is equipped with a pump to provide pressure for its use.
CUC requires these tanks to have an air gap distance of at least two times the size of the incoming CUC waterline and the maximum water level of the tank, Iglecias said.
CUC regulations, he added, require that the customer’s water storage tank should be constructed with an “appropriate sized air gap between the inlet pipe to the tank and maximum water level of the tank.”
In order for CUC to comply with the Safe Drinking Water Act, he said they must ensure that there are no cross-connections with other water supplies.
Cross-connection allows the backflow of contaminated water, or other dangerous, unsanitary, or un-potable substance, from the customer’s premises to CUC’s water supply system, Iglecias said.
“CUC is dedicated to protect its water system from the possibility of contamination or pollution from cross-connections,” he added.
A cross-connection is an actual or potential connection between the public water supply, CUC water, and a source of contamination or pollution.
Iglecias said one potential source of contamination is through the water line that provides CUC water into a customer’s water storage tank.
He urged customers to check if their water connection has the appropriate sized air gap between the CUC inlet and the maximum water level inside the tank.
