Our Mission


To provide an efficient service in the design of stormwater drainage systems that are required by local councils in the state of New South Wales including Basix, OSD, OSR and overland flow..


We are a civil engineering firm with in excess of 20 years experience, who's aim is to simplify the mystery of current storm water design requirements.

We are proud members of the Institution of Engineers Australia,

IPWEA and Housing Industry Association (HIA).

We would like to thank our customers for their

continued support and recommendations.


We hope you walk away from this site with a little extra knowledge about storm water drainage designs that New South Wales local councils are now expecting.

Our current service is only for builders nominated on this website. The information contained on this website is general to assist all, and should only be used as guidance and not an actual design or consent for a particular design.
