Atlan Stormwater Detention
During peak rain events, on-site Stormwater Detention (OSD) helps to slow run-off from developed areas – an essential flood mitigation strategy. Impervious surfaces and reduced infiltration are characteristic of urban development, and these cause stormwater to pool and increase flood risk.
Modelling sites to meet the demands of increased stormwater run-off ensures the on-site capacity to capture stormwater in underground detention assets. The design of OSD tanks allows them to capture peak run-off volumes during storm events and slowly let them go once the storm has passed.
