Authority staff will start work on the project next month, which will give customers greater pressure from their taps for everyday water use.

GWMWater acting managing director Andrew Rose said the staged work was necessary for Horsham’s growth and development.

“This is positive news for customers and businesses in Horsham. These water pressure increases will also provide growth opportunities for new and current investors to the city,” he said.

Mr Rose said the improvements would mean new commercial developments in the city would not require the installation of large and costly on-site water tanks to be able to meet building codes and standards.

GWMWater also anticipates the Country Fire Authority will benefit from the work, because greater water pressure will be available from fire hydrants.

Mr Rose said the changes would benefit customers during times of high water use; however the higher flow rate will also mean more water is used than before in a given period.

“Customers are encouraged to adjust the timers on any automatic watering systems and may wish to consider other water-saving measures such as shorter showers,” he said.

Mr Rose said customers who did not want to receive a higher water flow could adjust the flow at the stop tap at their water meter.

He said the project would not involve any major external contractor costs.

GWMWater does not anticipate the work will cause any changes to water quality.

However it has advised customers noticing any sediment in their tap water after the pressure increases to clear this by running the tap nearest their meter for a few minutes.

Mr Rose said people could call 1300 659 961 for more information about the changes.
