Pricing variations

For some groups of customers, different charges or some discounts apply.

Changes to our prices for 2017–18

Each year, our prices are reviewed and set by the State Government, as part of the State Budget process. In making its decision, the State Government considers the cost to provide water, wastewater and drainage service and the impact any changes will have on you, our customers.

From 1 July 2017, water use and service charges will increase by 6% on average.

Changes to seniors discounts

From 1 July 2017, the service charge discount available to eligible seniors will be capped at $100. The cap is divided into 3 individual caps as follows:

  • Water service charges – $18.14
  • Wastewater service charges – $72.69
  • Drainage service charges – $9.17

The total discount you receive will depend on the service provided to your property and your entitlement.

We are here to help

We understand the impact these changes may have. We look at every situation on a case-by-case basis and have a range of flexible payment options that can be tailored to meet your needs.

Vacant land

All properties with access to our water main or wastewater (sewer) main pay service charges – even if there is no connection. This contributes to the cost of providing and maintaining essential services.

Drainage charges may also apply for metro areas. 

If any water is used on your vacant land you will also be billed for this.

For vacant land, the water service charge is the same as for residential properties – $250.39 per year.

For vacant land these charges are based on the rateable value, or gross rental value (GRV), of the property. 

The sewerage tariff is 2.425 cents for each dollar of rateable value. The minimum sewerage charge for vacant land in the metro area is $303.87 and for country vacant land is $265.93.

The drainage tariff is 0.651 cents for each dollar of the rateable value. The minimum metropolitan drainage charge for vacant land in 2017–18 is $113.93. Drainage charges don't apply to regional customers.

Vacant lots created by subdivision

Vacant lots created by subdivision receive an exemption from service charges for up to 12 months from the approval date. The exemption ends when one of the following occurs:

  • the property is sold within the 12 month exemption period
  • a water or sewer connection is made to the property within the exemption period
  • the 12-month exemption period expires.

Multiple residences or strata titled served by one meter

The number of residences are taken into consideration when they share a water meter or account.

Sewerage and drainage charges are based on a property’s rateable value, or gross rental value (GRV). When we issue one account for a group of residences, the rateable value is multiplied by the number of residences. For example, for 10 residences: 

  • Sewerage – 4.198 cents applies to the first 10 x $20,500 = $205,000 of the rateable value.
    3.100 cents applies to each dollar thereafter.

    The minimum sewerage charge for 10 residences is 10 x $404.14 = $4,041.40 

  • Drainage – The minimum charge would be 10 x $113.93 = $1,139.30

The water service charge for strata titled units sharing a meter is $250.39.

If a number of residences are sharing a meter, the amount of water at each tier is multiplied by the number of residences. For example, for 10 residences 10 x 150 kilolitres (kL) = 1,500 kL is available at the first price tier. 

Caravan bays

Long-term residential and strata titled caravan parks are charged at different rates to other homes.

Water service charge

The annual water service charge is $175.98 per bay.

Sewerage service charge

The sewerage service charge is $310.34. Volume charges for sewerage also apply if you discharge more than 75 kilolitres (kL) of wastewater. The charge is $3.453 per kL discharged.
