When do you need an Aerated Wastewater Treatment System?

If your property is in an area that is not connected to the sewer main, you may need an on-site wastewater treatment system.   Contact us for a free site inspection.

What is an Aerated Wastewater Treatment System?

An AWTS is a mini treatment plant for your house, also known as an On-Site Wastewater Management System.  All the water from your toilets, sinks, baths, showers and laundry goes into the AWTS.  The tank is usually installed underground with just the lid and control panel visible.

How does it work?

The sewage and greywater will go through several processes.  The first reservoir works like a traditional septic tank where the solids sink to the bottom with the wastewater on the top.  The wastewater then flows into the next compartment where aeration takes place and bacteria digests the waste purifying the water leaving it odourless and colourless ready for recycling.

The Aerated Wastewater Treatment System recycles wastewater from your house and treats it in an environmentally sustainable way.  The water goes through several processes until the it is clear, which then can be re-used for irrigation in your garden.

Advantages of an Aerated Wastewater Treatment System

The AWTS treats the water to a superior standard compared to a septic tank.  Because of the natural process it is environmentally friendly, saves a considerable amount of water and means gardens can be maintained during drought.  The AWTS recycling system is a cost effective waste management system.


Your AWTS options can be quite varied and will depend on your site conditions and your level of requirement. Council will require a Wastewater Report to be submitted with your application.


We can guide you through the council approval process and work with them on your behalf.

Wastewater Report

We can recommend a wastewater industry consultant to do a wastewater management assessment on your property. 


The consultant will visit your site, analyse the physical aspects of your property, look at the wastewater requirements of the development taking into consideration your requirements and then will design a solution for the disposal of wastewater on your site. 


Once you have the Report you will have a clearer understanding of which treatment systems is suitable for your property.  We can then recommend a reliable Australian made system to suit your specific conditions.

Aerated Wastewater Treatment System Servicing and Maintenance

Your AWTS requires regular maintenance to make sure the system is operating to the highest possible standard.  The water purity will need to be monitored to make sure it meets Health Authority requirements.

 

The service contractor will replenish the disinfection; replace chlorine tablets or clean/replace the  UV lamp if required.  The AWTS has internal filters that require maintenance each visit.   When the system has an air pump the intake filter is checked, cleaned or replaced.

 

The overall condition of the entire system is inspected and noted down in the service records and kept in the history for future reference and problem solving.
