Trade waste

What is liquid trade waste?

 Liquid trade waste means all liquid waste other than sewage of a domestic nature.

 Liquid trade waste discharges to the sewerage system include liquid wastes from:

• business/commercial premises (eg. beautician, florist, hairdresser, hotel, motel, restaurant, butcher, service station, supermarket, dentist)

• community/public premises (including craft club, school, college, university, hospital and nursing home)

• industrial premises

• trade activities (eg. mobile carpet cleaner)

• any commercial activities carried out at a residential premises

• saleyards, racecourses stables and kennels that are not associated with domestic households

• septic tank waste, chemical toilet waste and established sites for the discharge of pan content from mobile homes/caravans to the sewerage system.

 

A business operator who wants to discharge liquid trade waste to the sewerage system, under section 68 of the Local Government Act 1993, must obtain prior approval from Council. Discharging liquid trade waste without an approval is an offence under section 626 of the Local Government Act 1993.

Liquid trade wastes may exert much greater demands on sewerage systems than domestic sewage and, if uncontrolled, can pose serious problems to public health, worker safety, Council’s sewerage system and the environment.

Managing liquid waste is important to our future. We can all play a part to ensure that our region remains a great healthy place for everyone. We care about our local community and the environment. Below is information to assist businesses manage trade waste.

Why do I need trade waste approval?

Sewerage systems are generally designed to cater for waste from domestic sources that are essentially of predictable strength and quality. Council may accept trade waste into its sewerage system as a service to businesses and industry.

Liquid trade waste may place significantly greater demands on sewerage systems than domestic sewage and, if uncontrolled, can pose serious problems to public health, worker safety, Council’s sewerage system and the environment.

If you discharge trade waste, you must have our written approval. If you are discharging trade waste without our approval, we may disconnect your premises from the sewerage system.

 

How do I obtain trade waste approval?

What is a Trade Waste Discharge Factor?

The Trade Waste Discharge Factor (TWDF) is the ratio of the volume of liquid trade waste discharge into the sewerage system to the total water consumption, expressed as a percentage. 

What is the process for having the TWDF percentage reviewed?

A property owner may request a review of the TWDF percentage if they believe the percentage of trade waste going to the sewerage system differs from the current TWDF for the property.

A property owner must complete the Application for Variation of Trade Waste Discharge Factor and include adequate supporting evidence to substantiate how the customer has measured or calculated the actual volume of trade waste discharged to sewer to support a change in the factor.

To submit an Application:

Complete the Application for Variation of Trade Waste Discharge Factor (PDF 375.7KB) and submit with supporting evidence by

  • Post to PO Box, 81 Dubbo NSW 2830,
  • In person to Council's Customer Service Centre cnr Church & Darling Street, Dubbo or cnr Namina Crescent & Warne Street, Wellington


When will the new TWDF be adjusted on the account?

Any approved change to the Trade Waste Discharge Factor as a result of a review will commence from the next water billing cycle and be issued with the next quarterly Rates Notices, in April, July, October, and January each year.  Variations cannot be performed for previous water billing periods.
