The Mt. Rose Pump Station is a wastewater lift station in Reno, Nevada. This project was brought to Romtec Utilities by Stantec to develop the scope and configuration of the lift station. Ultimately, Romtec Utilities was used as the basis of design. At the time of bid, Romtec provided this complete pumping system to the contractor, KG Walters, and to the Truckee Meadows Water Authority.
This wastewater lift station was designed to meet the standards of the Lakehurst Naval Air Station while remaining cost effective. A duplex pump configuration utilized submersible 7.5 HP Weil Slicer Pumps to handle suspended solids in the sewage. A UL listed control panel was designed and manufactured in a NEMA 4 enclosure for outdoor operation. Nolta floats were used for the in-well liquid level sensing. The below-grade structural components were designed and supplied precast concrete vaults painted with a marine epoxy exterior coating to prevent moisture incursion.
An upscale beachside community in California needed this medium flow wastewater lift station to replace septic systems used at each home. To meet the requirements of the beachside location, this system includes Ameron T-Lock PVC lining on both a precast concrete sump and emergency overflow basin. A below-grade vault contains the system’s valve and meter assemblies. Large bluffs between the beach and the city treatment plant required super-high head submersible pumps. The system electrical controls comprise redundant controls and level sensing with SCADA integration.
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.
This package pump station was designed to meet a low flow of industrial process water with added low flows of industrial stormwater. The dual purposes of this pump station required shaft-driven centrifugal pumps with the motors located above-grade.
