The flow and pressure values provided in the certificate are a estimate provided by a mathematical model of the water supply system. They should not be treated as a guarantee of supply.
The calculated hydraulic information provided in water pressure certificates is valid for 12 months from the date of the conducted test.
The values are not representative of conditions at all times of the day or season. They are subject to variables, such as:
- proposed system augmentations
- variations in system demands
- changes in hydraulic operation of the network.
Developers please note that we undertake pressure and leakage management programs that may result in a reduction in water supply flow and pressure.
We cannot guarantee residual water pressure greater than 12m in Council's water supply main at the hydrant under fire fighting conditions.
