Southern Wastewater Consulting prepares wastewater assessments, OSSM reports and effluent disposal reports across the Illawarra and South Coast, including Wollongong, Shellharbour and Kiama council areas.

​

Email us on info@southernwastewater.com.au to start the process. 

​

We prepare clear, compliant reports to support development applications, new builds, extensions, system upgrades and subdivisions on unsewered properties. Our assessments cover on-site sewage management systems including septic systems, AWTS and effluent disposal design.

​

We also service surrounding South Coast and hinterland areas where on-site wastewater systems may be required.

​

What's unique about wastewater design in Illawarra and South Coast

Wastewater conditions vary considerably across the Illawarra and South Coast. Steep escarpment areas, high rainfall, shallow or variable soils, smaller lots, environmentally sensitive land and proximity to waterways can all affect how wastewater can be safely treated and dispersed on-site.

​

We assess the land and soil conditions, identify practical wastewater options and prepare a design that suits the property, proposed development, environmental constraints and budget.
