The council will conduct tests to map the areas around Spring Hill where water can flow into the aquifer, which is the main source for water for the two villages.

The maps could be used to manage water quality and to reduce any potential water contamination risks as water moves from one area to another.

Council spokesman Nick Redmond said the research was part of managing the district’s water supply.

“The more information we have, the better the water supply can be managed,” he said.

When the testing begins on Sunday, the main Spring Hill bore will turned off for two days to stabilise underground water levels.

Pumps will then be turned on and used solidly for two days – water levels in four other nearby bores will be measured to determine where water flows from to re-fill the main Spring Hill bore.

During the two-day period when the water bore pump is turned off, the main reservoir at Spring Hill will be supplied by potable water trucks.

“Locals nearby the reservoir may notice some water carting trucks on Monday and Tuesday next week,” Mr Redmond said.

The carted water will be sourced from the Orange drinking water supply, which is fluoridated.

“Residents may see trucks coming and going from the reservoir, and they may notice a slight change in the taste of the water compared to their usual drop,” Mr Redmond said.

“We hope the result will be a better understanding of the connection between groundwater reserves.”
