Technical Guide on On-site Stormwater Detention Tank Systems

In the latest revision to the Code of Practice on Surface Water Drainage, PUB added a new clause requiring developers/owners to manage their peak runoff by implementing on-site detention measures (e.g. detention tanks and/or ABC Waters design features) to hold back or slow down runoff before discharging it to the public drainage system. These on-site detention measures will complement PUB’s ongoing drainage improvement works to provide a higher level of protection against flood risks in our catchments.
