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.

Who needs an AWTS?

 

 

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.

What is an AWTS?

 

 

 

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.

How does it work?

The AWTS 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 AWTS

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.

AWTS Servicing and Maintenance

AWTS require 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.

 

Indicators that your AWTS needs immediate service:

 

  • Unusual smells around the tank or irrigation area

  • Damp or soggy soil, or surface ponding

  • Discoloured grass (dark green) around irrigation trenches

  • Toilets or drains slow to drain or backing up

  • Grease trap is full or blocked

  • Blocked sprinklers and outlets

  • Any audio or visual alarm warning on your system

  • Overflow from the surcharge gully

  • Gurgling from the house drains

We can assist with the design of hour new Septic System and help with your Council application.  Our expert team can guide you to the best solution for your property and the environment.

Septic Tank Repairs, Service and Maintenance

Septic tanks require regular pumping out, depending on the amount of use, every three to five years is recommended.  An inspection every few years, to check the scum and sludge levels, can extend this period to match system use and will save your trenches / irrigation area from the transfer of sludge from a 'solid' septic.  This helps to keep trenches operating effectively also saving you the need to ask us to clean up and repair your existing trenches or sometimes needing to install brand new ones

When the system has an anaerobic (septic) tank, the scum and sludge levels and the condition of the tank needs to be checked.  If the septic tank is fitted with an outlet filter, it needs cleaning to ensure transfer to the secondary treatment chamber or tank.
