Southern Wastewater Consulting is a specialist wastewater consultancy, delivering clear, Council-ready on-site wastewater consulting 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 focused on our core business: on-site wastewater assessments and reporting and land capability assessments. This leads to fast turnaround times in site visits and completed reports, 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 consulting, onsite sewage management 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 sewage assessments 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 approval the first time.
