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.

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.

To create new potable water, this lift station pumps clean stormwater from a collection/storage basin to a treatment facility. Duplex vertical turbine pumps move high flows of water very efficiently and use soft starters to reduce torque on the vertical shaft and provide additional pump diagnostics. Also included is an above-grade valve assembly on the top slab. The control panel utilizes an ultrasonic transducer for primary level controls and a pressure transducer for backup. The entire package lift station is located inside an owner-supplied control building.
