What are the benefits of water pressure management?
Managing the water pressure will help the pipe network last longer as well as save around 7 billion litres of water each year.
Why are you investigating my suburb?
Suburbs are assessed and prioritised based on the water pressure they receive, the number of leaks and breaks in the pipe network, overall water use and suitability of the area. If your suburb is identified as a high pressure area requiring works, you will receive notification approximately six months in advance.
Will other suburbs be investigated?
The program is part of a state-wide program that is being implemented over 10 years.
What will my water pressure be?
The water pressure will vary from service to service depending on the pipe network, contours in the land and customer types. However, all pressure managed areas will be designed to deliver a water pressure greater than our required minimum standard of 15 metres head.
What does metres head mean?
Metres head is the measurement used to determine water pressure. It refers to the height (head) that water would rise vertically in a pipe. For example, 25 metres head of pressure would allow water to rise to a height of 25 metres.
How does pressure management work?
The process involves isolating a high pressure area from the general water network and installing specialised equipment. This includes advanced pressure control valves to gradually modify the water pressure until an optimum level can be maintained. This equipment will detect times of higher demand and ensure an increased volume of water is provided at the same pressure.
Will I notice much change in my water pressure?
This is dependant on a number of factors, including your current water pressure, location of your house and internal plumbing. In our trial suburbs of Rossmoyne, Shelley and Waterford, over half of the residents reported seeing little to no effect on their water pressure.
You may notice a change if you have special or unusual water using devices, such as dialysis machines, reverse osmosis units, water demisters, large aquariums, or if you think you may already have low water pressure. We want to hear from you if you use water for these purposes. Please contact the team on the details provided at the bottom of the page.
What if I have a problem with my water pressure?
If you think you may already have low water pressure you can carry out this simple test:
Step 1: Write down the black and red numbers on your meter, making sure all taps and water using devices are turned off first.
Step 2: Turn on your front garden tap for 60 seconds. Make sure you collect this water and use it to water your garden or pot plants.
Step 3: Take another meter reading and subtract the first meter reading from the last. This will tell you how much water came out within the 60 second period.
If your current pressure is a concern to you, Water Corporation can arrange to test the pressure for you at no charge. You will not need to be at home when they do this, they will just be accessing your water meter and a front tap.
Will my garden irrigation still work with changes to pressure?
Advice from industry experts indicate correctly installed and maintained systems will work with pressures of 20m to 25m, and the majority of our network will receive pressures greater than this.
You may experience reduced “throw” from your sprinklers. We will visit you free of charge if you would like someone to offer advice about the configuration of your garden irrigation system. If your irrigation system operates from a private bore then there will be no change to its operation.
Will my dishwasher, washing machine, hot water system and toilets still work the same?
Some appliances may take slightly longer to fill after pressure management has been introduced into your area.
Most hot water systems and dishwashers are designed to work with pressures of 15m to 20m and pressure management will deliver pressures greater than this. You may want to contact the manufacturer of your appliance to seek reassurance.
Will network efficiency projects impact the pressure of fire services?
We need to hear from you if you have special or unusual water using devices such as fire hose reels, fire hydrants, fire sprinkler systems or other water fire fighting systems. Please contact the team via (08) 9420 3667 or email firstname.lastname@example.org
For more information please refer to the fire flows brochure available for download at the top of this page.
I run a business in the area, what impact will the pressure changes have on my business?
This will depend on your business and its location within the identified area. All non-residential customers will be identified from our records and we’ll contact you to outline any potential impacts.
Will the water pressure management program be rolled out to all water services across the State?
No. Suburbs are assessed and prioritised based on the water pressure they receive, the number of leaks and breaks in the pipe network, the overall water use and the suitability of the area. For example, pipe configuration or lots of hills may make an area impractical to implement pressure management.
Water pressure in my suburb is already low – will these pressure works reduce my pressure even further?
No. Areas currently receiving low pressure will not receive water pressure management.
Where else is water pressure management implemented across the world?
Water pressure management is common in Europe, and is also in place in parts of Queensland and Sydney. Many water utilities throughout the world have existing programs to manage pressure or are working towards it.
