Yes. We will provide you with all the information required by the Water Corporation for self-monitoring of Trade Waste.

The Water Corporation routinely audit and analyse wastewater entering the sewerage system. Your business will be charged a daily fee, depending on the quality and quantity of the wastewater. This fee will need to be paid until the Water Corporation return for another audit- usually a minimum of 3 months’ time, this could be very expensive for your company. With approval for self-monitoring, the water can be re-tested as requested, with new results superseding previous results. This gives a business a chance to clean up their discharge and in turn, reduce their Water Corporation fee.
