For all trade waste enquiries please call the Trade Waste Hotline on (03) 6422 5444 or email

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) and Commercial Customer Pre-treatment Guidelines.

Category 0 Trade Waste Customer means a customer discharging trade waste of very low volume or strength, equivalent to or less than that of a standard residential dwelling.
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 basic pre-treatment devices (eg screens).
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.

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:

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

      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 see our  Commercial Customer Pre-treatment Guidelines for further information. Typical pre-treatment drawings are listed below.

Frequently Asked Questions

Changes to Trade Waste Accounts from 1st July

For these business activity types that have compliant trade waste equipment, TasWater will be removing the Trade Waste charge so we can focus our attention on more significant matters;

  • Animal boarding
  • Church/Place of worship
  • Green grocers (retail shops only)
  • Hairdressers/beauty salons
  • Primary schools
  • Medical centres (excluding dentists)
  • Ice creamery
  • Espresso shops & juice bars
  • Sandwich shops
  • Delicatessens

TasWater has created a new customer classification that applies to Juice bars and Espresso bars. Espresso bars are defined as businesses that serve coffees and food without food preparation done on site. The new Trade Waste category that is applied to this customer type is a Cat 0 which has no charge. This is because of its expected low impact to TasWater's sewer infrastructure. 

All water & sewage fixed charges, and water use variable charge, are billed to the property owner. 

TasWater has reviewed our customer base and found some sites were not charged as required under the new Price and Servicing Plan.  We have updated these charges in line with the new Trade Waste Customer Category Guidelines as required by our regulator.

The removal of Trade Waste charges have also led to a recalculation of sewer ET (Equivalent Tenements) charges, which is calculated depending on the number of hair basins.  To make things fairer, we’ve changed more than 1 element of charging. Sewerage charges were previously calculated at 0.79ET’s per basin, but from July 1st 2022 will be 0.25 ETs per basin – that’s a threefold reduction in sewer charges.

Previously for customers charged more than 1 ET, TasWater reduced the ET charge by 1 ET to accommodate the trade waste charge. 

For this PSP using the new sewer charge calculation, only salons with more than 4 hair basins will be charged more than 1 ET.  

The new Price and Services Plan (PSP4) defines a charge per bedpan macerator.  This will be implemented this PSP and the charge will be $56.62 per bedpan for the 2022/23 Financial Year.

Note that in-sink macerators are strictly prohibited.

The medical business activity code included Dentists, veterinary clinics, beauty salons and funeral parlours.  We are now only charging dentists and have created a new code.  We charge dentists due to the risk mercury poses to the cost of operating the sewer system.

TasWater routinely monitors and inspects its sewerage network and any problems created by unauthorised trade waste can be traced to individual properties. If a business is found to not be complying and/or has inadequate pre-treatment, we may send a letter to the property owner, implement non-compliance charges, implement fines, or even request that a property owner disconnect from TasWater's sewage infrastructure under the Water and Sewerage Industry Act 2008.

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.

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.
