​​​​​​​What's New?  ​

The 2026 Water and Sewerage Price Determination Investigation is underway.

The Tasmanian Economic Regulator is reviewing TasWater's costs and, at the end of the investigation, will determine the maximum prices TasWater can charge for regulated services between 1 July 2026 and 30 June 2030.

A draft report will be released in February 2026, followed by a 6-week public consultation.​

Our Role

TasWater is the only licensed provider of essential water and sewerage services in Tasmania. Because most Tasmanian's rely on its services, the Tasmanian Economic Regulator ensures that TasWater operates in the long-term interests of consumers.

We do this by:

Monitoring and reporting on TasWater's performance





Protecting customers by specifying minimum service standards and monitoring TasWater's performance against those standards.​​



Setting water and sewerage prices

​​​We regulate prices for:

  • The supply of drinking water
  • The collection, treatment, and disposal of sewage
  • The collection, treatment, and disposal of trade waste (some trade waste customers negotiate prices directly with TasWater).
We do not regulate prices for:
  • Water used for irrigation or for generating electricity
  • Stormwater services
  • Recycled water
  • Developer services
  • Private plumbing work

*Note: We approve a suite of miscellaneous charges, including some listed above.



Pricing Principles
Prices for regulated services must comply with legislated pricing principles.

The objective of the pricing principles is to:

  • ​ensure prices are efficient and incentivise TasWater to reduce costs; and
  • In relation to the provision of regulated water and sewerage services to customers, allow TasWater to:​

​(i)    recover the efficient costs it incurs; and

(ii)   receive a return on the assets it requires to deliver those services.

​​​
Customer Protection​

TasWater must follow the Customer Service Code​, which includes:

  • Meeting billing and service standards
  • Following complaint handling procedures
  • Providing access to hardship support.

If you're not satisfied with TasWater's response to a complaint, you can contact the Tasmanian Ombudsman.
