Packaged Sewage Pump Station

MAK Water’s Packaged Sewage Pump Stations (PSPS) are designed to receive raw domestic strength sewage into a below ground collection tank. The raw sewage is macerated to ≤ 2mm particle size, before discharging to a wastewater treatment plant for treatment. The standard package includes a polyethylene tank with access cover and all required PVC pipework, valves and fittings, dual macerator pumps, lifting chains and guide rails, dual pump controller and float level switches.

A range of common flow rates and tank sizes are provided to suit most wastewater applications. Optional equipment upgrades are available, including tank and access cover materials and a valve chamber; if required.
