jweddell1,000gpm - 5,000gpm, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

This unique package wastewater lift station was designed to meet the high sewage flows of this US Army Corps of Engineers managed reservoir and nearby campgrounds. Vertical chopper pumps were engineered above the sump in a precast concrete structure with the above grade valve assembly. Two inlet lines were engineered with extra piping to direct influent toward the bottom of the sump. The structure also contains the UL listed control panel. Float controls were used for liquid level-sensing, and the control panel included soft starters typical for vertical shaft pumps.

The City of Arcata | Arcata, CA | 2,947 GPM - 34.2' TDH

jweddell1,000gpm - 5,000gpm, Municipal Collection, Municipal Lift Station Replacement, Pacific, Wastewater

This “turnkey” replacement lift station was designed, supplied, and installed to meet super-high sewage flow with infiltration and inflow requirements of a municipal wastewater lift station. Submersible solids-handling pumps in a triplex configuration were installed. The below-grade valve assembly includes plug valves, check valves, ball valves, a pumping port, and a pigging port. The UL listed control panel has an ultrasonic transducer for primary liquid level sensing, redundant float controls, and an autodialer alarm. VFDs were also included in the lift station controls.

City of Santa Barbara|Santa Barbara, CA|1,500 GPM - 66' TDH

jweddell1,000gpm - 5,000gpm, Airports, Pacific, Sewer System Expansion, Wastewater

This lift station serves a large area and was installed at Santa Barbara Municipal Airport as part of a larger project. Two submersible solids handling pumps are supported by a jockey pump that acts as a sump pump for periods of low flow. An impressive control building contains the UL listed control panel, a backup diesel generator and automatic transfer switch, electric meter main, and ferrous chloride odor controls. The electrical controls interface directly with the existing detailed SCADA system used by the Goleta Sanitary District.

jweddell1,000gpm - 5,000gpm, Detention Ponds, Pacific, Parking Lot Drainage, Stormwater, Stormwater Runoff

A new Walmart Supercenter required this package stormwater pump station to handle runoff from its large impervious parking lot. A good sized detention basin collects the runoff water during a storm event, including from surrounding properties. Ebara submersible pumps then empty the detention pond at a high flow rate through just 45’ of force main into a gravity line that flows to treatment. An outdoor UL listed control panel includes float controls for primary and backup liquid level-sensing and a basic alarm for communications.

jweddell1,000gpm - 5,000gpm, 100-Year Storm, Mixed Use, Pacific, Stormwater, Stormwater Featured, Stormwater Runoff

This stormwater pump station was designed to handle variable flows of stormwater runoff. The typical stormwater expectations called for low flow pumping, but this pump station needed to handle high flows as well. Two different sizes of submersible centrifugal pumps were used; a 7.5 hp pump and a 25 hp pump. The pumps required differently sized discharge piping and valves for each pump. A PLC control panel handles all lift station functions including starting and stopping on level, SCADA options, an autodialer for communications, and a soft starter for the large pump.
