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.
