Advanced Secondary Treatment Systems (ASTS) are designed to treat all the waste water that is generated on a non reticulated site, this could be your business premise or your home. You may be familiar with septic systems, however the ASTS delivers a very high quality water treatment which means that the treated water can be reused. Reuse can include irrigation, dust suppression and wash bays.

There are two terms that you may of heard of ‘black water’ (water from toilets and kitchen waste) and ‘grey water’ (water from showers, basin and laundry). With an ASTS our plumbers can design a system that treats this water to give it a second use for garden irrigation, dust suppression and vehicle washing. ASTS can only be installed in certain locations, so it is important that you get the right plumbing advice from a Darwin local.

A waste water treatment system replaces a septic tank and delivers a much higher quality of treated waste water. Waste water treatment systems must be regularly serviced to ensure that the high quality of treated waste water is maintained.

Gold Medal Services develops site specific solutions to meet client needs. As local plumbers in Darwin and surrounding rural areas we ensure that your system is looked after over the long term.

The high water quality means that treatment systems can be placed closer to bores and water ways and meet with environmental health regulations.

Gold Medal Services only installs and provides ongoing servicing for products that have been approved for installation in the Northern Territory. For more information on local guidelines visit: Northern Territory Waste Water Management Guidelines
