A large neighborhood received these two lift stations that were designed to handle medium sewage flow requirements. The submersible solids-handling pumps in duplex configurations were specified to handle influent from three inlet lines from different sections of the neighborhood. The below-grade valve assemblies hold the system operation valves, bypass pumping ports, and shut-off valves. The outdoor UL listed control panels utilize pressure transducers and redundant float controls for liquid level-sensing; basic alarms were included for communications.
The City of Shafter|Shafter, CA|110 GPM - 28.4' TDH
This package lift station is part of a sustained plan to expand the collection system of a large sewage treatment plant completed in 1999. The medium flow is handled by submersible solids handling pumps in a duplex configuration. A pigging port, plug valve, shut off valve, mechanical indicator, back flow actuator, and swing check valve are all contained in a below-grade valve vault. An outdoor control panel includes an autodialer for communications, conductive probes for level sensing, and an intrinsically safe barrier for in-well electrical controls.
Burbank Housing|Sebastopol, CA|36 GPM - 26.8' TDH
This wastewater lift station was required to hand medium sewage flows from a development neighborhood by Smith River Rancheria, the governing body of the Tolowa Dee-ni’ Tribe. Two Goulds Water Technology 2 hp grinder pumps were used to meet the high head requirements for over 3,000 ft of force main. A owner-supplied control building contains the control panel and an permanent onsite Cummins generator for backup power. A Mercoid pressure transducer provides primary level-sensing controls with Dwyer floats for backup.
Lennar Communities|Bakersfield, CA|297 GPM - 57' TDH
This package wastewater lift station handles sewage flows from this large residential development neighborhood. Duplex submersible solids handling pumps pump a high flow rate from this 30’ deep wet well. The wet well includes an interior fiberglass lining and exterior coating. A below grade valve vault provides easy access to the valves, ports, and gauges. For level controls, the outdoor control panel includes a pressure transducer and floats for backup. An autodialer and backup generator are also included in the panel design and supply.
Del Norte County | Eureka, CA | 220 GPM - 36' TDH
To extend the sewer system for Crescent City in Del Norte County, this sewage lift station was added to a new gravity line and force main. Duplex submersible chopper pumps pump the sewage to an existing gravity line and on to treatment. An easy-to-access below grade valve assembly contains the check and plug valves. An outdoor PLC panel is connected to a customer-supplied generator and is also protected by a customer-supplied shelter. Primary liquid level sensing is by a pressure transducer with floats as a backup.
