The City of Hayward (City) owns and operates the Water Resources Recovery Facility (WRRF), located at 3700 Enterprise Avenue, Hayward, CA 94545. Part of this facility includes the North Vacuator, an above ground concrete structure built in 1958 with mechanical components and a self-supported concrete dome roof. The interior mechanical apparatus involves an exterior roof mounted motor that drives a shaft connected to an interior spindle connected to an upper rake arm assembly and a lower rake arm assembly. The vacuator tank is approximately 50 feet in diameter, 20 feet tall, with a sidewater depth of 10.25 feet. The interior of the North Vacuator is accessible by a manway in the dome roof and a temporary ladder. A stairway system provides access to the dome roof.

The North Vacuator is currently out of service for repairs. Repairs will include coating rehabilitation of interior structural steel components, application of coatings on interior concrete surfaces, interior concrete surface repairs (Types 1, 2, and 3), and grinding of edges of sludge and scum collector equipment as required for coatings.
