In larger commercial developments, there is often the requirement for one or more pump stations when liquid is unable to be discharged under gravity. These devices act as a holding chamber to collect stormwater, sewage or another wastewater. The pump stations then transport the waste for reuse or disposal by utilising transfer pumps.
Stormwater is the rainfall that runs off impervious or saturated surfaces in urban environments, such as roofs, roads and pavements, as well as green spaces. Where the environment is undeveloped, rainwater infiltrates soils, allowing for transpiration by vegetation and evaporation into the atmosphere. Where this natural occurrence cannot occur, stormwater runoff collects sediment and gross pollutants before entering the water way.
Global Water have been utilising the Austral Safety Covers on their SA Water Pump Stations. The range are a functional solution for water authorities who recognise the need for a safe solution for pump station maintenance personnel.
Global Water recently commissioned a sewer pump station for SA Water near the RAAF base at Edinburgh, north of Adelaide. Previous firefighting practises saw PFAS enter the underground aquafer and subsequently contaminate the ground water.
