Wastewater generated from businesses via industrial and trade activities, is not necessarily toxic but can be harmful or cause damage to the wastewater system if it is not managed properly. Clutha District Council manages trade waste via the Water Services Bylaw.
The Water Services Bylaw 2019 has been adopted by Council and came into effect on 1 July 2019. The Bylaw regulates the discharge of trade wastes to the wastewater system.
Under the bylaw relevant trade waste dischargers are required to obtain a trade waste consent. The bylaw sets limits for substances acceptable for discharge, pre-treatment required for some discharges, and also lists prohibited substances.
Help protect our pipes
Do you have leftover cooking oil or fat? Pouring grease down the sink can lead to fatbergs, which are large clogs formed by grease and plastics, potentially blocking sewer lines. To ensure proper disposal, follow these steps:
- Cool the oil
Allow used cooking oil to cool completely to avoid fire risks. This may take a few hours. - Use a suitable container
Pour the cooled oil into a non-breakable, resealable container, like an old jar. - Dispose of properly
Seal the container and place it in the rubbish bin. - Consider reuse
If you cook frequently, you can reuse cooking oil to save money and reduce waste.
What Not to Flush
- Wipes
Includes wet, baby, and make-up wipes; they don’t break down and cause blockages - Tampons
Don’t flush used tampons as they don’t break down - Dental Floss
Flushing floss (nylon or silk) leads to blockages - Cotton Buds (Q-tips)
Made of plastic, they don’t break down and can contribute to fatbergs - Pills and Prescription Medication
Flushing unused medication harms the system; take it to a pharmacy for safe disposal. - Condoms
Though made of latex, they take a long time to break down - Nappies and Disposable Diapers
These expand in water and clog pipes; dispose of them in a bin instead of flushing. - Any foreign materials: including old clothing and undergarments
Dispose these items in the thrash (or pharmacies for medication).
