We run an expansive network that delivers water across Western Australia. However, it is not always possible to maintain a continuous water supply at our usual quality and pressure standards in some areas.

Some properties are unable to access a water supply that meets the standard level of service required under our operating licence.To be able to supply water to these properties, we enter into an agreement with our customers.

If you live or work in an area with a non-standard water service, your water could be impacted by one or more of the following conditions:

If you need to apply for an additional service or reticulation service, please visit our building and development non-standard services page to find out what you need to do.

How do I know if my property has a non-standard water service?

Some property owners will be notified about their non-standard water service at the time the property is connected to the scheme.

If you have purchased a property with an existing non-standard water service, you should be advised by the previous owners or settlement agent. We will also send you a letter and a copy of your non-standard service agreement.

Your settlement agent should lodge a Section 70A against your property. This will show up on your title, which can be found in the Landgate Property Interest Report.

If you are a tenant, your property manager or owner should have advised you of the non-standard water service.

Frequently asked questions

If you purchase a property with an existing non-standard service agreement, you should have been notified in the following ways:

  • The previous owner is responsible for initially informing prospective buyers of the service conditions for the property.
  • If a customer lodges a property inspection report, they will receive the property information including any known non-standard service agreements.
  • When the settlement agent lodges a request of sale, we will issue a Certificate of Charges that includes information on existing non-standard service agreements.
  • We will also send a letter advising of the non-standard conditions that apply to the water service.

If an internal review of our systems identifies that a property receives a non-standard service, we will notify you.

Depending on your water condition there’s a few things you need to take into consideration.

Potable when treated water: You will need to treat your water before using it for drinking purposes. Untreated water can only be used in situations where there is no risk of consumption or inhalation. For more information please visit our drinkable water when treated page.

Non-potable water: Your water is not potable and cannot be consumed under any circumstances. Read more about sourcing an alternative potable water supply.

Continuity: As we can’t guarantee continuous delivery of the customer’s water supply, you will need to store 2 days’ worth of water on-site at your property. For more details, please visit our disruption to supply page.

Water pressure: To understand more about what you need to do if you have low or high water pressure please visit our non-standards water pressure page.

Flow rate and meter not on property: You don’t need to take any action as a result of receiving this information. This information is so you can understand the conditions of your water supply. If you would like more information about these conditions, please visit our flow rate page.

We supply water to properties with a non-standard service agreement on the provision they accept the conditions of supply. We cannot guarantee any improvements will be made to these conditions.

We regularly undertake projects across WA to improve and maintain our water supply network. The water service to some properties may improve as a result of these upgrades.

Find out more about some of our current and upcoming projects.

Having a non-standard service agreement in place does not impact your water bill charges.

Service charges and water use charges can differ depending on the property location, land use, and applicable water tiers and rate schedules.

Find out more about our fees and charges.

Most non-standard water supplies are due to the topography of the land, the remote location of the property or the types of water sources that are available. Because of this, non-standard service conditions can often apply to other properties within the local area.

But in some circumstances, this isn’t always the case. For example, if several different water sources supply a single shire, one property may have drinking water while another may have a non-potable water supply.
