One-part and two-part tariffs

One-part and two-part tariffs

The NSW Government has introduced a non-urban water metering framework which commenced on 1 December 2018 putting in place new metering requirements across the state. From 1 December 2019, all users with pump sizes 500mm or larger will be required to comply with the metering requirements. The staged rollout for metering requirements will continue until 2023.

You can read the policy and its supporting documents to find out how you are affected or contact the NSW Water Reform Task Force with any questions

The water management charges for your unregulated river or groundwater licence can be billed under a one or two-part tariff. This billing structure might act as an incentive for customers to have their water take metered or assessed.

If you are billed under the one-part tariff, the entitlement charge is applied to your licence volumetric ML entitlement or unit shares.

Under the two-part tariff your water take is metered or assessed and you are billed for:

  • lower entitlement charge (than under the one part tariff) applied to your licence volumetric ML entitlement or unit shares
  • water take charge applied to your ML of usage
  • water take reading/assessments charge or a meter service charge (if your meter is a corporation meter)

Regulated river licence holders are all required to meter their water usage and are billed under the two-part tariff.

Application for the two-part tariff

Complete the application to be billed under a two-part tariff (PDF, 208.62 KB) and return the application form to us via email or contact the Customer Helpdesk on 1300 662 077. A determination will be made and you will be advised in writing if your application was approved.

If your application is successful:

  • You might not be able to revert to a one-part tariff
  • The two-part tariff will be charged from 1 July of the year following the year of your application. This is to ensure that the full year water usage is metered or assessed.

Having your water take assessed

Metering your water take is the best way to determine how much water you used during the billing period and provide WaterNSW with evidence of your water use. Metering your water take will also provide you with accurate, real time information you can use to improve your water efficiency and achieve cost savings.
