Southern Wastewater Consulting delivers clear, reliable wastewater assessments to support development approvals and system upgrades across the Liverpool City Council Local Government Area. We specialise in on-site sewage management system (OSSM) reporting that aligns with Liverpool City Council requirements for new dwellings, secondary homes, subdivisions and commercial projects.

​

A small, experienced team focused on one thing—efficient delivery, high standards, and fair pricing.

​

As residential and commercial growth accelerates across Liverpool — with major greenfield precincts, infill development, and increased pressure on existing services — wastewater planning has become more complex. Many peri-urban and rural pockets remain unsewered, requiring high-quality wastewater assessments to demonstrate safe, compliant and sustainable on-site treatment. Our expertise ensures your proposal navigates these complexities with confidence.

​

We prepare wastewater assessments in the Liverpool region for:

• New homes, granny flats and dual occupancies in unsewered or constrained areas

• Upgrading, replacing or relocating existing OSSM systems

• Subdivisions, boundary adjustments and larger multi-lot developments

• Commercial sites including schools, food premises, health services, agritourism and other high-use facilities.

 

Each report includes:

• Detailed site and soil analysis

• A wastewater system design tailored to the property’s constraints, capacity and long-term sustainability

• A scaled site plan illustrating disposal areas, buffers and required setbacks

• Demonstration of how it aligns with Council and WaterNSW requirements

• Recommendations on suitable treatment systems — septic, AWTS, greywater systems, composting units, absorption beds and more.
