Southern Wastewater Consulting – wastewater assessments in Wingecarribee Shire Council
Southern Wastewater Consulting delivers clear, reliable wastewater reports across the Wingecarribee to support development applications and system upgrades. We prepare on-site sewage management (OSSM) reports that meet Wingecarribee Shire Council’s requirements for new homes, secondary dwellings, subdivisions and commercial projects.
Our small, agile team and specialised focus allow us to deliver premium quality work quickly and at lean costs.
If your property in the Wingecarribee is not connected to the reticulated sewer network, Council will require a wastewater management plan as part of the approval process.
assessments explain how wastewater can be safely treated and managed on your land in a practical and sustainable way.
We provide wastewater reports throughout the Wingecarribee for:
-
New houses, cabins and granny flats in unsewered areas
-
Replacing, relocating or upgrading ageing or failing systems
-
Subdivision proposals or boundary changes
-
Commercial and tourism developments such as cafés, cellar doors, farm stays, schools or accommodation.
Every report includes:
-
A detailed site and soil assessment
-
A system design tailored to your property’s constraints and opportunities
-
A scaled site plan showing disposal areas, buffers and required setbacks
-
Clear recommendations for suitable systems, including septic tanks, AWTS, composting toilets, greywater systems, absorption and irrigation areas.
We also carry out wastewater testing and effluent sampling in the Wingecarribee. Testing checks system performance against key indicators including nitrogen, phosphorus, E. coli and BOD. Results are explained in plain English so homeowners, designers and Council officers can easily understand system condition and compliance.
With more than 15 years’ experience in wastewater consulting, soil science, geology and regulatory compliance, our aim is to provide reports that are practical, accurate and ready for Council lodgement.
