Trade waste is controlled by laws to help protect drainage system treatment plants, which are essential city assets.
If your business is producing more liquid waste than that of a large household, 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 need 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 can take 20 working days. 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.
