If you are working on a property development that connects to a public water supply, you probably need to consider installing a detention tank. Many properties in Australia may already have OSD systems in place – such as industrial, commercial and special use buildings, such as schools and townhouses.
OSDs, otherwise known as On-Site Detention tanks are now required by law, for all new and recently renovated developments, in certain regions of Australia. These detention tank systems are meant to support urban development, by providing protection to the community, by ensuring that all development activities do not add to the risk of floods. It is a known fact that the capacity of the existing storm water drainage system is very limited and the capacity of the storm water, to soak to the ground is restricted in extent. This means that on site detention tanks, should be made a part of your planning and development processes. That is, if you are in the renovating process or building a new property.
The recent changes in land use and advancements in construction, including removal of much of our natural landscape has resulted in no place for rainwater to collect. Hard surfaces, such as site drainage, roofs, pavements, etc. have shown a swelling in the volume of the storm water run-off. If left unchecked, this becomes a cause for concern, for owners of companies, lands and homes, due to the high risk of flooding and overburdening of the existing storm water infrastructures.
How do on site detention tanks work? During a rain event, OSDs capture the rain water on site and stores it temporarily and to be released slowly, through a controlled orifice or a small diameter release valve, into a public storm water system. Slowly discharging of rain water lessens the flow of water, during a rainfall, hence also lessens the impact on streams or downstream infrastructures.
Especially, buildings with large roof areas can collect a large volume of rainwater; if it is allowed to flow freely, may overwhelm the storm water drainage system of your community. On site detention tanks detain the storm water and deliver a controlled release that stop storm water surges. Typically, on site detention tanks are specified by councils in areas, where there is a potential flooding risk. The current increase in housing in the country, makes its storm water system undersized. So as a general rule, if you are either extending a building or constructing a new one, in areas that are prone to flooding, then it’s very likely that you will require to install an OSD.
