On-site Stormwater Detention Tank Systems

In the latest revision to the Code of Practice on Surface Water Drainage, PUB added a new clause, which required developers/owners to manage their peak runoff by implementing on-site detention measures 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 protectio​​n against floo​​d risks in our catchments. To provide guidance to QPs on the design of detention tan​ks to manage peak runoff, PUB has developed a set of technical guidelines.
