Commercial Customer Repayment Program

To reduce the risks associated with trade waste TasWater created the Commercial Compliance Program, to help Tasmanian businesses become trade waste compliant by installing pre-treatment systems to mimimise the amount of trade waste entering our sewerage network. To support our Category 2 trade waste customers TasWater is offering a no-interest repayment scheme to help cover the cost of installing or upgrading a compliant trade waste pre-treatment system.

Program details

  • Repayment contracts are available to owners of property that house a TasWater Category 2 trade waste customer
  • Applications can be submitted from 1 July 2018 to 30 June 2019
  • Minimum value is $5,000
  • Repayment scheme contract period is four (4) years
  • Repayment contracts are offered with no interest and available for up to 80 per cent of the total cost of works and equipment required to meet trade waste compliance. Customers must contribute 20 per cent before they can access the full repayment amount
  • Applicants must provide a detailed quotation for the approved installation as part of their application 

What if my business is already compliant?

TasWater will discount trade waste fixed charges by 10 per cent for four years* for eligible category 1 and 2 trade waste customers that have already completed their trade waste compliance upgrades.   Category 1 and 2 customers that become compliant during the four year period* without accessing the Commercial Customer Repayment Program are also eligible for a 10 per cent discount. Discounts will apply at the commencement of the next quarter after compliance is gained, and will automatically be applied to the nominated TasWater account once proof of compliance has been verified.

*The four year period for compliance and associated discounts applies from 1 July 2018 to 30 June 2022
