Westernport Water is improving the reliability of your water supply.
Why are we undertaking this program?
The pipeline pressures in some water supply areas of the Westernport Water’s distribution system are high compared to those of other Victorian water corporations. The objective is to have your water pressure between 20m – 50m head (~500kPa) in compliance with the recommendation by Water Services Association of Australia (WSAA).
What are the benefits of this program?
By reducing and controlling water pressure it may increase the life of your appliances and reduce the likelihood of damage. High water pressure may contribute to burst water mains, leaks and water waste. By extending the life of our water supply pipes and assets we will minimise maintenance costs.
Where will this project occur?
The seven water supply zones that will be targeted are Cape Woolamai, Newhaven, Rhyll, San Remo, Smiths Beach/Sunset Strip, Sunderland Bay and Surf Beach. The first zone will be Cape Woolamai, which will occur later this year.
$0.9M (Seven zones). Cape Woolamai ($130,000).
Why do some areas have higher pressure than others?
Water is distributed to customers from an enclosed water storage basin located on a hill above San Remo. The pressure at any given property will vary depending on its elevation above sea level and distance from water storage.
The Water pressure management brochure provides further information.
Frequently Asked Questions
What is water pressure?
Water pressure determines how fast the water flows through your pipes. Water Services Association of Australia (WSAA) recommends that water pressure should be 20m – 50m.
What is a Pressure Reduction Valve (PRV)?
A PRV reduces pressure in the water network. Westernport Water will be installing PRVs on the water main where the water pressure is higher than the desirable limit. There maybe a PRV already installed on your property to help manage your water pressure. In the past, some customers have installed a PRV to protect their internal plumbing and appliances from the high pressure. The PRV is usually located just after the main water line enters your property, near the tap on your water meter and before the main shutoff valve.
An example of a PRV:
What is water pressure management?
Pressure management involves reducing and controlling the water pressure to a set pressure.
Do I need to remove my PRV if I have one?
It is not expected that customers will need to remove their existing domestic PRV. However, PRVs may be required to be adjusted if the water pressure is below expectations.
What should my water pressure be?
The objective is to limit your maximum pressure to 50m head (~500kPa) in compliance with the maximum desirable pressure recommended by WSAA.
I have a fire suppression system installed, will it still work as expected?
Customers with any type of firefighting systems installed, are encouraged to check the impact on their systems in accordance with the expected pressure reduction. The expected pressure and flow information at those locations can be provided by Westernport Water on request.
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. 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.
