Congratulations on embarking on one of life’s most exciting adventures! Before you can start building, there are a number of things you need to check off your list.

If you have just purchased land and you are doing your own settlement, you will need to inform us, so that we can link the property account to your name.

Step 1: Get building approval from us

Anyone building an area served by either a Water Corporation water or sewer main must submit a building application and pay the associated application fee. Your builder will handle this for you, but it’s best to speak to them first to make sure they are taking care of that application.

All applications are submitted via our our self-service system Buildernet. If you're an owner-builder and need to submit the application yourself, here is a simple guide to using Buildernet.

Step 2: Are you connected?

Not sure if your property is connected to water* or sewer services? Do you want to find out where they are located? Here is how you can find out.

For more details on water and sewer connections please read our help article.

*All services are not always available.

Step 3: Requesting a water meter

Your builder will request a new meter/service connection for you as part of your building application. Find out more about applying for water meters and the related fees and charges.

Step 4: Installing waterwise features

While you’re choosing what makes your house a home, think about how to make your home waterwise. Our top tip is to talk to your architect or builder early about your options and the kinds of waterwise features you’re considering. This might be:

  • Installing water efficient fixtures such as waterwise showerheads
  • Making space for a rainwater tank, or even have it plumbed into your house to flush toilets or wash clothes
  • Installing a greywater system
  • Designing a waterwise garden

Step 5: Update your property details

When your build is completed, please contact us so we can update the property details from ‘vacant land’ to ‘residential’ and change your postal address.

Vacant land service charges

It’s important to know that even while your new home is being built, all water use and service charges will be issued to you (the property owner). These bills include the water that is used onsite during the building process.

Looking after your meter

Please ensure there is adequate access to water meters on your property, to prevent you from having to make modifications down the track. We require access to read, repair and replace your meter.

While most reputable builders should be aware, if you have engaged a builder or contractor to carry out work you will need to ensure:

  • Ensure relevant clearances around and above the meter  
  • If the ground level of the property is altered and this impacts access to the meter, please advise Water Corporation. The landowner will be responsible for costs associated with raising/lowering the water meter or box to the appropriate level.
  • If you have a meter box, please regularly remove build-up of soil inside the box and ensure the meter is clear of dangerous insects and spiders where practical.

Any re-instatement or costs associated with gaining access to meters is the responsibility of the landowner.

Frequently asked questions

You will firstly need to speak to a licensed plumber to relocate the internal pipework and find a suitable location for the meter. Once this is completed we can relocate your meter.

Concession discounts only apply once the house is built and you are living in it. No concession discounts apply to building application fees and charges.

An adjusted charges bill is simply the first service charges bill you will receive from us.

An easement is a notification on your title deed outlining where restrictions may apply. It may affect the approval of your proposed building depending on the structure type.

Under the Water Services Act 2012, we manage and control building activity in proximity to its assets, regardless of the existence of an easement. The creation of notifications on titles is a relatively new process. Therefore, some sewers located within properties do not currently have easements.

The easement serves as a notification to prospective purchasers of the existence of the sewer. As subdivision leads to the construction of new buildings it is important that purchasers are aware of any encumbrances or restrictions that may be placed on their building.

The costs and yields from a rainwater tank can vary significantly in Perth.

Our weather patterns can result in tanks being full at some times of the year and empty at other times, such as in summer and other periods of low rainfall. We support customers who choose to install a rainwater tank but don't believe that this cost should be introduced to all new homeowners.

New houses are generally quite water efficient as building codes require the use of water efficient appliances, lot sizes are relatively small and waterwise planting and hardscaping are often used to reduce water use. For this reason, large scale installation of rainwater tanks remains an option for the future.

Depends on the type of subdivision - Strata or Green Title and Vacant Strata or Built Strata. You need to apply through the WA Planning Commission (WAPC). Please contact our Development Services Business Unit on 9420 2099 for further information.
