Rodney and Carl started Sewerage Service Diagram as a service to the plumbing industry in 2009. At that time, Sydney Water ceased preparing sewerage service diagrams and made plumbing licensees responsible for providing them as part of their compliance obligations.

As this change also affected home owners, home sellers and home buyers, we began preparing sewerage service diagrams if plans for building alterations were halted or sales transactions were delayed because no sewerage service diagrams were available. Very often, the non-existence of a sewerage service diagram occurred because changes were made to the drainage system without a final inspection being conducted.

An additional service we provide to the plumbing industry is the preparation of drawings for newly installed hydraulic services, commonly termed ‘As Builts’ or ‘As Installed’ or ‘As Constructed’ drawings.

We prepare sewerage service diagrams and ‘As Built’ drawings using the AutoCAD program for a quick and professional service.
