Wastewater System Assessments

Contact us

Know the system. Avoid surprises. Buy with confidence.


Onsite wastewater systems are often overlooked during property inspections, yet they can be one of the most expensive and complex assets on a property. Our wastewater inspections provide clear, independent advice to support Healthy Homes compliance and pre-purchase decision-making.


We assess existing wastewater systems to identify visible defects, performance issues, compliance risks, and likely future costs—helping you make informed decisions before committing.

Healthy Homes Standards – Wastewater Inspections


While wastewater systems are not explicitly tested under the Healthy Homes Standards, a failing or non-compliant system can directly impact a property’s habitability, safety, and suitability for rental use.




Our inspections help landlords and property managers by:


Identifying signs of system failure or poor performance


Highlighting maintenance or compliance risks


Flagging issues that may affect tenancy, council compliance, or insurance


Providing practical recommendations to address issues early


This service is ideal for landlords seeking reassurance that their wastewater system is fit for purpose and not likely to create compliance or tenancy issues.


Pre-Purchase Wastewater Inspections


A standard building report often excludes wastewater systems. Our pre-purchase wastewater inspections fill that gap.




We provide buyers with an independent assessment of:


The type and age of the wastewater system


Visible condition and signs of failure


System suitability for the property and occupancy


Maintenance and servicing requirements


Likely future upgrade or replacement risks


Our findings help buyers:

Understand potential costs before purchase

Negotiate with confidence

Avoid unexpected consent or repair issues after settlement
