What is Stormwater?
Stormwater is the rain water running off a property or landscape from the rain that falls on the impermeable area such as roof tops and land, and everything the stormwater carries with it. The dirt, earth, organic matter, rubble and fertilisers from gardens and oil residues from driveways it carries can pollute downstream waterways. Therefore managing stormwater is essential to preserving our environment in Perth, WA.
Rainwater usually refers only to the rain that falls on the roof, which is usually purer. Additionally, stormwater can be a valuable and treasured resource. Reusing rain or stormwater can save usable water and reduce downstream environmental impacts exponentially.
In Perth's residential areas stormwater Perth is generated by stormwater draining from roofs, roads, driveways, footpaths and other impervious or hard surfaces. In Australia the stormwater drainage system is separate from the sewer system. Unlike sewage, stormwater is generally not treated before being discharged to waterways and the sea.
Stormwater drainage that is not managed can cause problems on and off site through erosion and the transportation of nutrients, chemical pollutants, litter and sediments to waterways. Good management of stormwater can substitute imported water for uses where high quality water is not required, such as garden watering. for greywater.
In Western Australia, soakwells are the preferred method of stormwater drainage, although sump systems and stormwater harvesting tanks are often used in suited suburbs.
