Santa Barbara Cottage Hospital|Santa Barbara, CA|1,095 - 21.5' TDH

jweddell1,000gpm - 5,000gpm, Hospitals, Pacific, Stormwater, Stormwater Runoff

This simple package lift station was designed to handle the medium flows of stormwater at this hospital facility. Submersible centrifugal pumps in a duplex configuration alternate pump starts or can both operate in high stormwater events. The pumps are protected from inflows by an HDPE deflector panel. There is a below-grade electrical junction box in a concrete vault. System controls were designed with a UL listed control panel, float controls for liquid level-sensing, a basic alarm, and an autodialer for telecommunications.

An IMTT industrial storage facility needed this stormwater pump station to collect runoff and pump it to treatment onsite. The duplex submersible pumps were engineered to handle the expected medium flows of stormwater. The pumps also needed to handle water that could potentially carry oil or other industrial chemicals stored on the site. An above-grade valve assembly used ball valves and check valves that were vertically integrated for easy access. The pump station electrical controls were located on an existing wall in the water treatment area.

The City of Santa Barbara needed this packaged pump station to manage low stormwater flows from events that occur during the dry season. Duplex submersible pumps capable of passing a 3-inch solid pump the water into an existing sanitary sewer pressure main and on to treatment. This pump station includes an in-ground valve vault with plug and check valves and stainless steel discharge piping to handle oily or contaminated water conditions. Romtec Utilities supplied the complete electrical controls with liquid level sensing, alarm notifications, pump start and stop cycles, above-grade disconnect stand, and intrinsically safe circuits.

The expansion of a college campus required this stormwater pump station to handle medium flows of stormwater runoff. To meet the required pumping rate, 7.5 hp Ebara submersible centrifugal pumps were designed in a duplex configuration. This pumping system was designed with dual force mains and check valves integrated in the discharge piping to simplify the engineering for the system. Romtec Utilities provided the complete electrical engineering plans for the UL listed control panel. Floats for primary and backup liquid level-sensing were supplied to give the system added redundancy.

Solyndra Commercial Complex

Solyndra|Fremont, CA|450 GPM - 35' TDH

jweddell300gpm - 500gpm, Pacific, Stormwater, Stormwater Runoff

This new commercial complex required two new stormwater pump stations designed to meet low flows of runoff. The manholes and hatches were designed at grade to integrate seamlessly with the brick patio and walkway. Submersible centrifugal pumps in a duplex configuration discharge to below grade valve assemblies accessible by valves cans. The UL listed control panels are contained by stainless steel NEMA enclosures and include intrinsically safe barriers. Both lift stations were designed with the same primary components for site standardization.
