Southern Wastewater Consulting is a specialist wastewater consultancy, delivering clear, Council-ready on-site wastewater and land capability assessments to support smooth development approvals across the Southern Highlands, South Coast, Southern Tablelands, South-West Sydney and the Capital and Snowy Countries.

​

We’re a small and experienced team of scientists with a sharp focus on our core business of wastewater assessment reports. That results in efficient site visits, fast turnaround times, leaner costs for our clients and practical reports that meet council requirements and keep projects moving.

​

Our services include:

  • On-site wastewater assessments and reporting (OSSM)

  • Land capability assessments

  • Wastewater testing, effluent sampling and laboratory analysis

  • Compliance and performance checks to support council and EPA requirements. 

​

With 15+ years’ experience and qualifications across wastewater assessments, soil testing and geology, we have a team that understands the technical detail, compliance requirements and the approval pathways to get your project Council approved. Unlike general environmental consultancies, on-site wastewater and land capability assessments are our core specialisation — not an add-on.

​

Our strong background in local planning controls, regionally specific soil conditions and environmental constraints allows us to deliver reports that make the right recommendations, are accurate, proportionate and ready for assessment the first time.
