Colusa County, California Combined-Cycle Plant Lift Stations
Combined-Cycle Plant Lift Station
This project highlights combined-cycle plant lift stations for a power generating station in Maxwell, California.
Maxwell, California is a farm community located along Interstate 5 about 68 miles northwest of Sacramento, the capital of California.
It is also located in Colusa County where the main crop grown is rice along with a variety of other foods including grapes, almonds, olives, sunflowers, and squash. Not far from Maxwell is the City of Colusa, which is the county seat of Colusa County, where the Sacramento River flows.
The Delevan National Wildlife Refuge is a 5,797-acre refuge for ducks and geese just outside of Maxwell.
Various attractions in Colusa include the Colusa National Wildlife Refuge, Colusa County Fairgrounds, Colusa-Sacramento River State Recreation Area, Calusa Casino Resort, Colusa Bypass Wildlife Area, Colusa Golf and Country Club, King Vale Park, C.D. Semple Park, Sankey/Elmwood Park, Will S Green Park, Colusa Levee Scenic Park, Colusa County Airport, and City Park.
The Colusa Generating Station Combined-Cycle Plant
The Colusa Generating Station is a 660-megawatt combined-cycle project located in the unincorporated portion of Colusa County owned by Pacific Gas & Electric Company.
The energy plant is a natural gas-fired, dry-cooled, combined-cycle electric generating facility, consisting of two General Electric (GE) Power Systems Frame 7FA combustion turbine generators.
The Colusa Generating Station uses a zero liquid discharge wastewater system, which recovers the water from the combustion turbine generator’s evaporative coolers for reuse in the plant. The remaining salt is concentrated for disposal off-site. The facility includes a water treatment system and an air-cooled condenser for cooling water.
Water for the plant is provided by the Glenn-Colusa Irrigation District (GCID) from the Tehama-Colusa Canal.

The Power Plant Lift Station Designs
Pacific Gas and Electric Company (PG&E) needed three new lift stations as part of the construction of the Colusa Generating Station, and it chose Romtec Utilities as the designer, manufacturer, and supplier for the plant’s water infrastructure pumping needs.
Romtec Utilities worked first with the civil engineering firm, Worley Parsons, to design each lift station for its specific purpose. Clear documentation was created for every power plant lift station to specify the exact configurations, manufacturing, and supply. The project’s general contractor, Gemma Power Systems, then purchased the three lift stations for installation. All three of these systems are being used as part of the wastewater management system for the facility.
Romtec Utilities provided all the necessary specifications and components to provide three long-term package lift station solutions for industrial process water, industrial stormwater, and wastewater.
These three package lift stations were designed to meet medium flows of industrial process water with added low flows of industrial stormwater and wastewater.
Submersible centrifugal Flygt pumps in a duplex configuration were specified to meet the peak flows and water chemistry identified for each combined-cycle plant pump station. UL listed control panels with floats for liquid level-sensing and basic alarms comprise the system controls for the lift stations.
These lift stations’ force mains are above grade as part of a pipe rack system which is very common in industrial applications. It allows for easier maintenance as they can access it above ground.
During the industrial water process associated with the heat recovery steam generators (HRSG) process, very hot water is pumped through the system which requires parts that can withstand this caustic environment.
These packaged lift stations were integrated into stormwater, processing, and wastewater plans for the new construction of the Colusa Generating Station.
The controls are tied into the overall site monitoring system. This allows for the power plant lift station error notifications to be seen in the control room of the facility.
Key Players in the Lift Station Project
Worley Parsons is an engineering services company of energy, chemicals and resources experts helping customers shift their operations towards a more sustainable future.
Gemma Power Systems is a leading engineering, procurement, and construction company providing innovative solutions for the power and renewable energy industry. They bring energy plants to life in the combined cycle, simple cycle, renewable/environmental, and hydrogen fields.
It was great to partner with PG&E, Worley Parsons, and Gemma Power Systems to bring these combined-cycle plant lift stations from concept to delivery in order to meet the pumping systems needed for this dual cycle power plant in Maxwell, California.
Romtec Utilities designs, manufactures, and supplies lift stations for power plants all over the country as we can handle the entire project seamlessly from start to finish. We even include an on-site installation tech to ensure the system is built per the design. We also provide commissioning and training on the operation of the system for maintenance personnel.
