The Non-Potable Booster Pumping Station NB-10.3 (NB-10.3) includes a dual zone booster station. NB‑10.3 includes two separate pump stations which pump out of the Non-Potable Reservoirs NR-10.3.1 and NR-10.3.2. One pump station (12 Zone Pump Station) will pump to the 12 Zone and the other pump station (11 Zone Pump Station) will pump to the 11 Zone. The 12 Zone Pump Station will initially be equipped with two 400 hp pumps (one duty, one standby) with a capacity of 3,100 gpm and pump can for future 400 hp pump. Ultimately, the pump station will be equipped with three 400 hp pumps (two duty and one standby) with a capacity of 6,200 gpm.
The 11 Zone Pump Station will not initially be equipped with pumps. Suction piping and three pump cans sized for 1,600 gpm pumps will be installed as part of the project. The project includes a 6,800 gallon surge tank, a manual transfer switch, and a generator termination box for connection to the District’s portable generator. The project involved working closely with and as an extension to District staff.
