Department of State Hospitals Metropolitan Water Tanks #1 and #2 Replacement Project

Department of State Hospitals Metropolitan Water Tanks #1 and #2 Replacement Project

The proposed project is located within the Department of State Hospitals (DSH) Metropolitan State Hospital campus, located at 11401 Bloomfield Avenue in Norwalk, Los Angeles County, California. The project site is located at the northeastern corner of Balsam Street and 9th Street (Assessor’s Identification Number [AIN] 8025-003-902). The proposed project would demolish the two existing 22-foot-tall, 750,000-gallon-capacity water tanks and the existing nonpotable water pumphouse, which is located behind Tank #2. The existing water tanks would be replaced by two new 40-foot-tall (maximum height), 80-foot-diameter, 1,000,000-gallon-capacity water tanks. The proposed project would also replace piping, valving, and appurtenances associated with the new water tanks and existing pumphouses, and would verify/complete connections from the existing 12-inch firewater main along Balsam Street and South Circle Drive to the existing sprinkler system supply lines in the hospital campus’ central kitchen, administration building, and skilled nursing facility. Construction of the proposed project would occur in two phases. Construction is expected to take approximately 12 months for each phase; Phase 1 is anticipated to begin in late 2025 and Phase 2 is anticipated to begin at the end of 2026.
