Trade waste applications

Before any discharge can occur, you will need to apply to Council for a trade waste consent explaining the type of work to be carried out and the discharge. If the discharge is acceptable, Council will issue a consent.

The consent will provide details of:

• the amount of wastewater that can be discharged to the wastewater system
• the type and amount of substances in the wastewater
• the type of pre-treatment needed
• servicing requirements
• the annual cost of the consent compliance monitoring.

The consent will include conditions to prevent:

• blockages
• sewer overflows
• interference or obstruction to the treatment process or network
• risk to public health and the environment.

Trade waste consent is valid for five years unless terminated earlier. All consents are non-transferable. If you sell or close the business, you must give 20 days’ written notice to Council or you may still be liable for associated costs.

Council manages wastewater and trade waste sources to prevent damage to our services and infrastructure and the environment. We manage and prevent sewer overflows, blockages, flooding, habitat destruction, and infrastructure damage while reducing the health and safety risk for everyone.

You may have to install a pre-treatment device and have it regularly maintained to meet consent conditions. All accidents and spills either causing damage to or allowing a substance to enter our network must be reported to Council immediately. You may also be asked to install a flow meter, which must be calibrated and monitored regularly so readings of discharge volumes are accurate.

Our staff will occasionally inspect, monitor, test, and sample to check you are complying. We’ll give you at least 24 hours’ notice before entering your property. In an emergency, 24-hour access must be granted to authorised officers without notice.

If you are convicted of breaching the bylaw, you may be fined up to $200,000 under section 242 of the Local Government Act (2002). You may also have to pay the cost of fixing any damage caused.
