An AWTS (Aerated Wastewater Treatment system) treats your wastewater by aerating it so it can be used to irrigate your property. AWT tanks have different compartments for treating wastewater and several pumps, so they require more maintenance than regular septic tanks. We work with Rivatec (Earthsafe) aerated wastewater treatment systems and can expertly maintain a range of wastewater treatment plants.


VR Marsden Plumbing also provides quarterly service reports to Councils on all types of AWTS (aerated wastewater treatment systems) including Earthsafe, Taylex, BioCycle and more. We have worked with Coffs Harbour City Council, Clarence Valley Council, and Bellingen Shire Council – providing expert services and maintenance.

Aerated Wastewater Treatment Systems

Onsite Wastewater Treatment Plants/Septic Systems

We’re specialists at installing and maintaining onsite wastewater treatment plants in Coffs Harbour, also known as septic systems. These are valuable systems for sparsely populated areas that don’t have access to a mains sewer system.

We work with traditional systems using absorption fields and non-traditional systems that rely on pumps or additional treatment. We can also help with identifying the most effective approach in any environment.

For health reasons, it’s important that septic systems work effectively. Our ongoing maintenance work for onsite wastewater treatment plants ensures that they continue to operate to the highest standards.

We specialise in supplying a wide range of durable and reliable pump stations, including both horizontal and vertical units for either commercial or domestic use.


Whilst there is a wide range of sewage pump stations available, we have the expertise to recommend the best solution for your site; this is usually based on the physical limitations of the site.
