What is Trade Waste?
Trade Waste is the discharge of non-domestic liquid waste into the sewer system. Examples are waste from meat works, hair salons or takeaway businesses.
All businesses that discharge a trade waste into the sewer must apply to the Timaru District Council for consent. The consent approval will give you strength and volume limits for the various components of the waste.
Currently no Trade Waste application fee is charged but there will be costs involved in modifying any connection to enable monitoring to occur.
In addition to a trade waste consent, any premise which discharges grease or fats must have a grease trap to ensure this grease does not enter the sewer.
There is a requirement that a maintenance contract be entered into with a service provider to maintain the capacity of the grease trap.
Industrial premises have their discharge sampled regularly for compliance.
Inspections for grease traps are undertaken.
Activities that require separation methods for wastewater and stormwater before discharge to the public sewer and stormwater systems are also monitored.
Fees and Charges
Commercial premises that are consented to discharge to the public sewerage system, pay Trade Waste charges.
