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 industrial pumping system was designed to handle medium flows of process wastewater created from cleaning cycles at the Merck Animal Health facility. The wastewater was specified with highly variable pH conditions, so the pumping system was designed with a double-wall fiberglass sump with leak detection. All of the submersible components in the well were constructed of stainless steel, including the Tsurumi duplex submersible pumps. The pumping system electrical controls comprised a UL listed panel with SCADA integration.
