After your drinking water supply has been filtered and disinfected at one of Western Water’s water filtration plants, the water is sent to storage basins and tanks located in elevated areas near the townships. The level of elevation provides the necessary pressure required to gravity feed water downhill to homes and businesses.
Water flow rates can vary, depending on a property’s height relative to the water storage tank, and a property’s distance from the tank. Properties located in high country are likely to experience lower water pressure than those properties located on lower ground. In some areas, pumping stations are used to boost pressure in order to supply water at an appropriate flow rate to service customers.
Our Customer Charter stipulates a minimum flow rate from a normal residential property service of 20 litres per minute at the water meter, 95% of the time.
Pressure fluctuations may be experienced from time to time. These are often due to usage demand on the system or the switching on or off of a nearby pumping station.
On very hot days when there is a greater demand for water on the system, the water pressure is likely to drop.
DO Mains Bursts Affect Water Flow Rates?
Western Water is equipped to respond quickly to water main leaks or bursts. We rely on our customers to inform us of leaks and bursts, so that we can immediately repair the main, minimise any water loss and return service to our customers. Water supply problems can be reported by calling 1300 650 425, 24 hours a day, seven days a week.
When the water main is turned on following a repair, it is done gradually to avoid pressure surges. The flow rate should gradually return to the same level prior to the interruption.
Can I Alter My pressure Rate?
Generally, water pressure is determined by the elevation of your property in relation to the water supply system. The pressure at your property is required to be at the level it is to ensure that the system operates adequately for all the customers on the supply system.
After tapping into the water main, it is the property owner’s responsibility to control the pressure of water within their property.
If the water pressure is too high for your various fittings and appliances, a licensed plumber can be engaged to fit a Pressure Limiting Valve to your property. The cost for such a valve, and its maintenance, is the responsibility of the property owner.
If you are experiencing continual low water pressure problems please contact Western Water on 1300 650 425.
