Commercial trade waste customers are businesses that discharge low to medium risk trade waste to sewer. For detailed categorisation please see our Customer Category Guidelines (PDF 220.4KB).

Category 1 Trade Waste Customer means a customer discharging low volume and low impact Trade Waste which is minimal risk to the Sewerage Infrastructure and can be managed through cleaner production methods.
Category 2 Trade Waste Customer means a customer discharging low to medium volume and low impact Trade Waste which requires physical pre-treatment at the source to make it acceptable for discharge to the Sewerage Infrastructure, and includes those customers in subcategories 2A, 2B and 2C as set out in the Price and Services Plan.



What does my business need to do?

Prior to commencing their business activity, trade waste customers must obtain a Trade Waste Consent to legally discharge into TasWater’s sewerage network[1]. This is
written approval from TasWater that sets the conditions and requirements under which a customer can discharge trade waste in to our network. The conditional acceptance of trade waste ensures we can safely collect, transport and treat the trade waste. If you believe your business is generating trade waste, please follow the steps below to apply for a Trade Waste Consent:

  • 3. We will contact you.

    One of our representatives will contact you about your application to:

      Explain your rights and responsibilities and answer any questions and arrange an onsite inspection of your premises to determine if a pre-treatment system should be installed or upgraded in order to meet TasWater’s trade waste requirements.

  • 4. Install/upgrade a pre-treatment system if required
      If the onsite inspection identifies it is necessary to upgrade or install a compliant pre-treatment system to meet trade waste requirements, TasWater will issue a Trade Waste Notice and provide guidance on the options available to complete the upgrade/installation. TasWater trade waste customers have an agreed time frame from the date they receive their notice to install the pre-treatment systems. Please find our pre-treatment guideline and typical pre-treatment drawings via the forms and fact sheet page here.

Will TasWater accept my trade waste?
Subject to an application and inspection, TasWater will accept the discharge of liquid trade waste in to our sewerage network, if:

  • Our infrastructure has capacity to collect, transport and treat your waste
  • The trade waste does not prevent the recycling of our sewage treatment by-products
  • You have explored and applied all practicable trade waste minimisation, recycling and reuse options.

What happens if I’m unable to install/upgrade a pre-treatment system as required by TasWater?
TasWater provides all our trade waste customers with an agreed timeframe to install or upgrade a pre-treatment system. During this period we can work closely with you to ensure you have all the information necessary to either install or upgrade your pre-treatment system. However, in the event a customer is unable to install or upgrade a pre-treatment system within the agreed timeframe, TasWater may charge the customer an additional fee. Please contact the trade waste team should you have any questions.

How does TasWater know if a business is complying with its Trade Waste Consent?

TasWater routinely monitors and inspects its sewerage network and any problems created by unauthorised trade waste can be traced to individual properties.

What to do if your business is no longer trading or property is now vacant?
If the trade waste generating business is ceasing or changing the business activity, the property owner is required to contact the trade waste team to advise of these changes, as a new application for consent to discharge trade waste may be required. The Property Owner is liable for any ongoing Trade Waste charges until TasWater is notified and a written confirmation is issued to the property owner that charges have changed or been ceased You must give not less than 30 days written notice to us of any of the following events:

  • Any change to the business conducted which may materially affect the Trade Waste discharge; 
  • Any intended change to the method of Pre-treatment; 
  • Any proposed transfer, sale or closure of the business or any proposal to cease possession of any part of the premises;
