Some project sites are in unsewered areas, and may require on-site effluent disposal, such as a septic system. Some may also consider on-site disposal for financial, environmental, or resource reasons. Our evaluation and design process helps you choose the best option and can be effectively used by builders, owners, plumbers, and system suppliers.
The PDF report is compiled and signed by a registered professional engineer, together with the qualified site and soil evaluator’s report. The design details typically include (where applicable):
With over 30 years’ design experience across thousands of Australian builds, we’re trusted by owners, developers, and builders across Australia.
With our own NATA accredited laboratory, we thoroughly test and analyse soils. Because we have full control over the testing process, we produce extremely reliable data for every project.
From order placement through to job completion, STA makes it easy for you to track the status of your project.
STA is a one-stop engineer with a service range that delivers three key advantages:
Pre-planning your engineering needs means you won’t have to keep re-booking an engineer when you need a particular service. It creates efficiencies that cut service times and save you money by pulling together the services you’ll need, at a lower overall price.
With all your engineering done by a single organisation, your consultants tap into a deeper knowledge of the site and the project, which leads to high quality outcomes, with more opportunities for innovative solutions.
While STA always takes legal responsibility for its engineering designs, an up-front engineering services package makes it easier to trust our work with a strong mutual commitment, and reduced risk of potential interruption or delay.
