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.

This package lift station system was designed to meet the medium sewage flows of this new residential development and private golf course. Submersible solids handling pumps in a duplex configuration manage the influent for this deep well, and an above-grade valve assembly maintains proper discharge operations. An outdoor UL listed control panel includes float controls and a basic alarm. This package lift station was one of the first systems installed for the Coyote Springs development after government approvals in 2010.

Romtec Utilities designed and supplied this wastewater lift station retrofit to meet the medium sewage flows at the Steven’s Pass Ski Resort. A major part of the retrofit supply package were two Vaughan submersible chopper pumps for wastewater. The electrical controls were the next significant portion of the retrofit. The PLC controller included a touchscreen HMI with autodialer telemetry and SCADA options to communicate with the resort treatment plant. This communication provides advance notification for the treatment plant as the lift station is nearly inaccessible during winter months.

This medium flow sewage lift station was designed for a new development to meet the Sammamish Plateau Water and Sewer District lift station design standards. These standards specify a PLC controller with touchscreen HMI, SCADA options, a precast concrete valve vault, wet well, meter vault, and duplex submersible pumps. In addition to these design standards, this lift station needed to tie-in to an existing force main owned by the District. Romtec Utilities provided the tie-in force main designs and calculations as well as VFDs (variable frequency drives) to match the changing flow and pressure conditions of the existing force main.

In order to expand the municipal sewer system, this lift station was configured to pump to an existing gravity line flowing to treatment. A 24-foot-deep by 10-foot-diameter wet well collects the sewage flows. The wastewater is pumped at 120 gpm 10,000 lineal feet of 10” force main against 206’ TDH with 23 hp high head submersible solids handling pumps. A sheltered control panel utilizes an intrinsically safe barrier for in-well electrical, such as the pressure transducer and conductive probe for primary and backup level controls.
