Waste Water Treatment

Professional Plumbing was the original company to supply and install residential and commercial Waste Water Treatment Systems. Today we supply two state of the art Waste Water Systems under the direction of Paul Bottomley, who is considered an expert in the Waste Water Industry, respected by engineers, developers and health authorities. 

Envirocycle is a unique system developed specifically to recycle domestic waste water treatment from the bathroom, kitchen and laundry and treat it in an underground tank constructed of concrete to a purity approved by relevant health authorities throughout Australia

Commercial business waste water needs can be completely addressed, we have installed water treatment systems at: Devils Corner Winery, Bruny Island Cheese and Piermont

• Envirocycle is concrete construction and manufactured in Tasmania. Envirocycle tanks are Jaz-Anz accredited and have a 15 year warranty on tanks. 

• Envirocycle is a unique 5 chamber filtration system based on anaerobic and aerobic bacteria to digest waste. This produces odourless water ideal for re-use in irrigating the garden.

• Full height of the internal 4 baffles means no cross contamination ie. raw sewerage cannot end up in pump out chamber and on your garden. 

• Large working capacity of 6400 litres (better with loads ie. visitors, parties. Shock loads can cause offensive odours), with overload capacity of 9300 litres. 

• Single tank system, simple to install and tidy. 

• First company in Tasmania to gain approval (first system installed in 1985 & still running beautifully). 

• Very low running costs – 10ANR has the lowest operating costs of ANY system on the market!

Included in general maintenance, various water quality tests are conducted on site and inspection records are kept.
