Southern Wastewater Consulting delivers clear, reliable and council-ready wastewater assessments and land capability assessments to support project's DA approvals across the Liverpool City Council Local Government Area.

​

We'd love to be part of your next project. Get in touch at info@southernwastewater.com.au or 0435 575 403 to discuss wastewater reporting needs for your project in the South West Sydney region.

 

We deliver on-site sewage management system (OSSM) reports that meet Liverpool City Council requirements for new dwellings, additions, renovations, secondary homes, subdivisions and commercial projects.

​

Our locally operating wastewater consultants servicing Liverpool and South West Sydney are focused on efficient delivery, high standards, a consultative approach with our clients, and fair pricing.

​​​

We understand Liverpool’s LGA is unique, and requires local experience. Wastewater planning is becoming more complex in the area, as residential and commercial growth accelerates across Liverpool's major greenfield precincts.

​

Many peri-urban and rural areas remain unsewered, including properties within or near the Sydney drinking water catchment, where protecting waterways and water quality is particularly important. These properties require high-quality wastewater assessments that respond to local site constraints and demonstrate safe, compliant and sustainable on-site wastewater treatment.

​

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.

​

We also deliver land capability assessments. For subdivision projects, a land capability assessment confirms at the earliest stage that a site can viably support on-site wastewater management before designs and lots are finalised. This can be a critical early step that saves time in the long run.

We serve all areas of Liverpool City Council LGA and neighbouring areas including Ashcroft, Austral, Badgerys Creek, Bradfield, Bringelly, Busby, Carnes Hill, Cartwright, Casula, Cecil Hills, Cecil Park, Chipping Norton, Denham Court, Edmondson Park, Green Valley, Greendale, Hammondville, Heckenberg, Hinchinbrook, Holsworthy, Horningsea Park, Hoxton Park, Kemps Creek, Leppington, Liverpool, Luddenham, Lurnea, Middleton Grange, Miller, Moorebank, Mount Pritchard, Pleasure Point, Prestons, Rossmore, Sadleir, Voyager Point, Wallacia, Warwick Farm, Wattle Grove, West Hoxton.

​

With 20 years’ experience in wastewater consulting, soil science, geology and regulatory compliance, our priority is to deliver assessments that are practical, technically robust and ready for Council submission — particularly important in a fast-growing area like Liverpool where demonstrating environmental protection and system resilience is critical.

​

Southern Wastewater Consulting is an independent, locally focused practice. We streamline the wastewater reporting process so your project can progress smoothly through Liverpool City Council’s development pathway.
