Waste Water Treatment Systems

Wastewater treatment systems are designed, installed and monitored to ensure operation and the quality of the treated wastewater is satisfactory for release back to the environment with minimal impact and with the greatest regard for public health.

There are three types of wastewater treatment systems:

Treatment System    Details
Greywater Treatment System 

Greywater is the term used to describe the waste water from bathrooms, laundries and kitchens. The term doesn't include toilet wastewater. Greywater is generally of sufficient quality that it can be treated and reused on gardens. 

Septic Tanks System 

The unsewered residential sections of City Beach use septic tank systems to treat and dispose of sewage, also referred to as wastewater. Septic tank systems consist of two watertight cylindrical tanks called septic tanks connected to two sets of drainage receptacles which have holes in their side and no base (ie. leach drains or soak-wells) .

Aerobic Treatment Units (ATU)

These units are a more advanced multi-stage alternative to conventional septic tanks and provide an improved quality of effluent treatment. As the units are still an onsite effluent disposal system they aren't accepted as an alternative to sewer requirements. The chlorinated effluent from ATUs may be used to surface irrigate garden areas but can only be used below grassed areas. ATU effluent can't be used in vegetable gardens.
