It is a legal requirement that all trade waste generators must obtain a trade waste approval, be subject to regular Audits from Trade Waste Officers who will advise on trade waste issues and ensure compliance under the Water Supply (Safety & Reliability) Act 2008, our Trade Waste Policy and Trade Waste Management Plan (TWMP).

Any business found not to be compliant with the relevant legislation and policy requirements will be granted a reasonable transition period to upgrade their present facility to meet the minimum standards.
