Our Aerated Wastewater Treatment System (AWTS) provides both primary and secondary treatment of domestic and small scale commercial wastewater. The system can manage an hydraulic load of approximately 2,500 litres per day, which is equivalent approximately ten (10) people.

This simple device separates leaves and other solid material that is washed off your roof during a rain event and diverts the first flow of water to ensure that the water delivered to your storage system is in the best condition possible. The diverted  'first flush' water is slowly released into the waste drain in preparation for the next rain event. The kit is suitable for 90 mm diameter roof drainage systems and the first-flush volume can be matched to your roof surface area simply by varying the length of of the first-flush column.
