The Project consists of constructing a new 1-million-gallon (MG) prestressed concrete circular reclaimed water reservoir at Southern California Logistics Airport (SCLA), located east of Westwinds Road and south of Montana Street (APN 0459-211-16) within the City of Victorville. The new reservoir will replace the existing 600,000-gallon in-ground rubber-lined pond used for reclaimed water storage.

The pond also experiences significant evaporation losses in this desert environment. Upon completion of the new reservoir, the existing pond and associated pumps, onsite piping, valves, and appurtenances will be decommissioned, removed, backfilled as necessary, and abandoned, thereby improving system reliability, operational efficiency, and overall water quality.
