Why On-Site Detention (OSD) is Essential in Stormwater Drainage for Land Subdivision Projects
Effective stormwater drainage management is a critical part of any land subdivision project in NSW. One of the most important requirements from local councils is the installation of On-Site Stormwater Detention (OSD) systems.
When land is subdivided, large areas are covered by impervious surfaces like roads, driveways, and rooftops. These prevent natural infiltration and dramatically increase stormwater runoff. Without proper drainage solutions, this excess runoff can lead to downstream flooding and severe pressure on the public stormwater infrastructure.
An OSD system addresses this by temporarily storing stormwater on-site, then slowly releasing it into the council-managed stormwater drainage network. This controlled flow reduces peak discharge rates, helping to prevent pipe overloading, property flooding, and erosion.
Councils across NSW enforce OSD requirements through their Development Control Plans (DCPs) and Water Sensitive Urban Design (WSUD) policies. These frameworks aim to promote sustainable stormwater drainage practices and reduce the environmental impact of urban development.
