Council Regulations for Soakwells and Stormwater
Regardless of local council regulations all stormwater drainage must conform to the Australian Standards set out in AS 3500.1/.3.
If you are interested in your local Western Australian councils regulations regarding soakwells please follow the links below and the document will open in a new window.
We recently contacted every council in the Perth metro area (Aug 2012) and the majority of them adhere to the 1 in 20 year rain event as the basis for the calculations. Two exceptions are the City of Gosnells and the Town of Cambridge who both specify volume requirements that meet the predicted rainfall for the 1 in 100 year event.
Councils that are not listed conform to, at a minimum, the building standards code of Australia and a minimum of the 1 in 20 year rain event for volume calculations.
If you have any questions regarding stormwater soakwell regulations please don't hesitate to contact us. Alternatively you can seek advice from the engineer of your local council.
