Residential water prices

Residential water prices

There is a state-wide price for most water services. Whether you're in a metropolitan or regional area, you pay the same price per kilolitre (kL: 1 kL equals 1000 litres) as every other residential customer in the state, no matter how much it costs to get the water to you.

If you are looking on tips to reduce your water usage, visit our pages on saving water inside and outside your home.

Your water charges comprise two parts:

  1. A fixed charge for water supply
  2. A variable charge for water use - the more you use, the more you pay.

Water supply charge 

The 2018-19 price for having water supplied to your home is $74.45 per quarter.

Recycled water price

We supply some customers with recycled water. That water is just for irrigation, gardens or flushing toilets. The water is supplied by dual reticulation, in purple pipes.

The price for recycled water is set at $2.120/kL in 2018-19, which is 90% of tier 1 water use prices.

Daily threshold explained

The daily threshold is used to calculate the water use charge for residential customers.

While we endeavour to read meters every 91 days, this is not always practical.  The date of your meter reads can be found on page two of your SA Water bill.

The amount of water used at each tier is calculated by assuming the same amount of water has been used for each day of the billing period. This ensures you are not advantaged or disadvantaged as a result of a meter reading date not falling exactly on the quarter.

For example, we may take 100 days to read your meter and you may also record consumption of 32kL for the quarter. Instead of applying the quarterly threshold of 30kL, we calculate your daily use and convert it to a quarterly amount. Based on 100 days this would provide you with a tier 1 threshold of 32kL for this particular quarter. If only the quarterly threshold (30kL) had been applied, you would be charged at a higher rate for the amount you have used over 30kL.

Definition of 'residential'

Residential properties include houses, maisonettes, home units, retirement homes, flats and strata/community title residences and vacant land.

How much water you should use each day

There is no right or wrong amount of water to use. An average residential customer uses 184kL  per year but this doesn’t take into account individual circumstances. The amount you use will depend on things like

  • the size of your property
  • the size of your garden and what type of plants you have in it
  • how many people live in your house
  • what water using appliances you have and their level of water efficiency
  • whether you have a pool
  • the season.

All these factors may influence your water use.

Charges for customers not connected to the water network

Customers with properties that are able to connect to a water main are billed a rating on abuttal charge. This is regardless of whether they use the service or not.

A rating on abuttal charge reflects the availability of the service should the current or future owners choose to connect the property. To make this connection available, the water network has been designed to accommodate connection and supply to these properties.

The availability of these services adds value to the property should the current or future owners choose to connect to our network.
