Confederate Tribes of Grand Ronde|Grand Ronde, OR|400 GPM - 30' TDH

jweddell300gpm - 500gpm, Pacific, Residential Development, Urban Growth, Wastewater

The Confederated Tribes of the Grande Ronde Community purchased this lift station to meet the medium sewage flows of a new housing development. Submersible solids handling pumps in a duplex configuration are protected from influent by two deflector panels on two inlet lines. A below-grade concrete valve vault provides easy access to the system valves, pressure gauges, actuators, and access ports. An outdoor UL listed control panel is protected by a shelter/shade structure. Liquid level-sensing is accomplished with a conductive probe and backup float controls.

County of Santa Barbara Seal

Santa Barbara County needed this package lift station to replace an existing system serving a residential area next to Goleta Beach. Ebara submersible sewage pumps were engineered in a duplex configuration to alternate starts and create redundancy in the system. Liquid level-sensing also includes redundancy by using Dwyer floats as the primary control device and a Multitrode probe for high-level backup. A UL listed control panel uses a NEMA 4X stainless steel enclosure to be safely located outside of the existing control building.

Culbertson Power Plant|Culbertson, CA|100 GPM - 25' TDH

jweddell50gpm - 100gpm, HRSG Blowdown, HRSG Pumping, Industrial, Industrial Water, Mountain, Power Generation, Process Water, Wastewater

This power generation facility installed a package lift station designed for medium sewage flows of industrial wastewater. To protect the submersible solids-handling pumps, an inlet line deflector panel was included in the design. The wet well was protected from off-gassing and corrosion by an interlocking fiberglass lining. Conductive probes are used for primary and backup liquid level-sensing with an outdoor UL listed control panel. The panel is outfitted with a basic alarm and an autodialer for telecommunications.

Walmart in Gardnerville, Nevada

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.

Green Sanitary District

Green Sanitary District | Roseburg, OR | 150 GPM - 56.8' TDH

jweddell100gpm - 300gpm, Collection Systems, Control Buildings Shelters, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

A large book distribution center required the local municipal agency to install this package wastewater lift station. The force main was installed via a horizontally drilled hole to the exact elevation of the wet well connection. The submersible solids handling pumps are explosion proof to meet the hazardous area classifications for this lift station. A sheltered PLC control panel contains an intrinsically safe barrier to also meet the hazardous area requirements. The panel utilizes a pressure transducer and floats for primary and backup level-sensing controls.
