This project provides a storage tank for the reclaimed water system, a component of the El Portal wastewater treatment system. The precast concrete tank with the dimensions of 33' 4" long x 7' 8" wide x 7' 11" deep will be installed underground and connect to existing the piping. It includes modifying existing flow meters, valves and piping associated with the newly installed reclaimed water system. This reclaimed water storage tank is to be used in the ultraviolet disinfection system.
