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.
Without effective stormwater management or treatment, stormwater can cause problems on and off site through erosion and the transportation of nutrients, pollutants, litter and sediment into our waterways.
Heightened awareness of the ecological effects of urbanisation has increased in recent years. Developers now seek to minimise adverse environment impacts on commercial or large-scale residential projects.
