Managing Trade Waste

Moa Point Treatment Plant

Businesses that produce oil, grease or other liquid waste may require a trade waste consent.

Liquid trade waste can cause environmental havoc if poured down the sink - blocking drains, damaging the Moa Point treatment plant and polluting waterways.

Trade waste is controlled by law, to protect drainage system treatment plants, which are essential city assets.

Trade Waste Consent

If your business is producing liquid waste in larger than domestic quantities, you may need a trade waste consent.

The Council grants consents on a case by case basis. Call the Council to discuss your situation with the Trade Waste Officer.

If it sounds like your business may require a consent, the Officer will assess your situation by looking at site plans, and the type and volume of liquid waste. Chemical analysis may also be involved. The Council officer’s evaluation will show whether or not you need a consent.

The decision as to whether a consent is needed or not can be made quickly. However, assessment and evaluation of the conditions to be set up for a consent can take a number of months. Temporary consents may be granted in such cases.
