Stormwater drainage is an essential part of the design of any development as it is required for all local government development applications (DA).

Abel & Brown is able to undertake the entire range of storm water drainage projects, from large commercial / industrial estates to stormwater concept plans for houses. We have undertaken works in most Local Government areas in Greater Sydney and major regional centres, and are familiar with their specific stormwater drainage and on-site detention requirements.

We are familiar with all rainwater reuse systems including the Action Tanks packaged rainwater reuse system as utilised on many Housing NSW projects.


We are well versed in the industry standard software packages:

'Drains' written by Watercom - Used for On Site Detention & hydraulic grade line analysis of stormwater drainage networks

'ILSAX' written by Dr Geoffrey O'Laughlin - Used for the sizing and temporal analysis of storm water drainage systems.

'HEC-RAS' written by US Army Corps of Engineers - Used for the analysis of overland flow and the effects of flood waters.

We also utilise a wide range of custom spreadsheets designed by our staff.
