Westech Engineering
Structural design of a 586 SF CMU pump building that was tied to the raw water intake off of Foster Dam. Treatment building is a PEMB structure of approximately 14,640 SF and is partially buried in a hillside. It includes a 2,880 SF mezzanine housing the control room, electrical room, conference room, office, locker room and observation deck. Under the building’s floor slab is a 450,000 gallon cast in place concrete Clearwell for chlorination of the filtered water. This project also includes two 8,890 SF concrete backwash ponds constructed adjacent to the treatment building. This system can treat up to 4,000 gallons per minute with the three existing filters and has the ability to be expanded up to five filters.
