On-site Wastewater Systems. ATU’s for sewer treatment and water re-use.
ON-SITE WASTEWATER SYSTEMS. AEROBIC TREATMENT UNIT’S FOR SEWER TREATMENT AND WATER RE-USE.
At Valmadre Homes water re-usage is a priority for not only us by also our clients, with our business based in the south west of Western Australia we are often building homes where our clients either do not have access to the sewer mains or the home is already connected sewer main or septic system but water re-use is a priority for the site. We use an Aerobic Treatment Unit (ATU) or a grey water re-use system if the home is connected already and we use a Grey Water Re-use system when the home is already connected to the sewer main. These whole-house systems treat all wastes to a secondary standard and the discharge water can then be used to irrigate gardens. With the majority of Western Australian soil being quite sandy with surfaces ranging from deeps sands to sands over clays, and soils dominated by ironstone gravels these systems are generally an owners only ability to irrigate their properties.

At Valmadre Homes we use two types of On-site Wastewater treatments.
AEROBIC TREATMENT UNITS (ATU’S)
When we have a property that does not have access to the sewer main, we regularly use an Aerobic Treatment Unit (ATU) to treat all sewer waste onsite.
All household fixtures including toilets are drained into the ATU.
The ATU is made up of a series of chambers that treats the waste with various stages, the end result being non-potable irritable water.
HOW IT WORKS
Wastewater is treated in several compartments. The first is similar to conventional septic tanks, where solids settle to the bottom and scum floats to the top. The partially clarified wastewater flows into a second compartment where it is mixed with air to assist bacteria to further break down solids.
A third compartment allows further settling of solids and a final chlorination compartment allows disinfection. The treated effluent, treated to a secondary standard, is then pumped away for surface or subsurface irrigation in a dedicated area or paddock, although chlorine is not ideal for irrigation
The main ATU system we install is a Fujiclean CE1500EX. (see below for link)
GREY WATER RE-USE SYSTEMS
Greywater is wastewater which does not contain sewage, typically coming from sinks, showers, and laundry facilities. All plumbing fixtures (except Toilets) can be plumbed separately to a grey water recycling unit. The water is held briefly in the tank where it is filtered and ready for re-use in the garden or even back through the toilet.
We use this type of on-site wastewater treatment when we have an existing home that is already connected to a sewer main or septic system and water re-use is a priority to our client.

What are the Benefits ?
- The main benefit is reduced water demands on the supply chain system.
- An ATU allows recycling every litre of water used inside the home. A family of 5 could recycle 200K to 300K litres per annum irrigating 150m2 of grass, plants or trees.
- Another benefit of an ATU is only using earth-friendly cleaning products making for a nontoxic home.
- Imagine irrigating every day of the week during water restrictions!
- Reduced water rates.
