What is Council’s responsibility when it comes to trade waste
Council is responsible for providing and managing water supply, sewerage and liquid trade waste services for its community. An important part of those responsibilities is the approval and monitoring of liquid trade waste discharges to its sewerage system in accordance with the Liquid Trade Waste Management Guidelines and Council’s liquid trade waste policy.
In order to accept liquid trade waste to sewer, Council must ensure that:
- its sewerage system complies with the Department of Environment and Climate Change licence requirements
- water conservation and waste minimisation are strongly encouraged
- there is no adverse effect on the environment or the health and safety of the public and Council’s employees
- the trade waste does not adversely affect the potential beneficial reuse of effluent and bio-solids produced at the sewerage treatment works
- it monitors discharges to ensure they comply with Council’s approval
- additional maintenance costs for Council’s assets arising from the discharge of trade waste to sewer are minimised
Important - prosecution and penalties apply
Section 68 of the Local Government Act 1993 requires that all trade waste dischargers to a council sewerage system must have an approval from Council. This applies to both new and existing trade waste dischargers. A discharger who fails to obtain Council’s approval or fails to obtain Council’s approval or fails to comply with the conditions of approval may be prosecuted under section 120 (1) of the Protection of the Environment Operations Act 1997. In addition, Council may issue a penalty notice under section 222 of that Act.
