As part of its regular maintenance program Wingecarribee Shire Council will start replacing the water meters in late October.

Under the water meter replacement project, about 2000 of the shire's oldest residential and industrial water meters, with the majority located around the Bundanoon and Bowral areas, will be replaced at a cost of $300,000.

Council's projects engineer Pranayan Giri said the water meters would be replaced at no cost to property owners.

"Water meters, like all mechanical devices, wear with age," Mr Giri said.

"Some of the water meters being replaced are either nearing or passed their useful life expectancy."

The water meter replacement program will be carried out by council's water and sewer reticulation staff members.

If residents are home on the day of the proposed works, council staff members will attempt to contact them prior to the replacement.

During the meter replacement, the water will be briefly disconnected (one to two hours duration).

Council staff members will advise residents at home to not use any water appliances during this time and to ensure all taps are turned off.

Once water supply is returned, it is recommended a cold water tap is slowly turned on to allow any trapped air to escape. If the water is discoloured on reconnection, it is recommended to run the tap at the rear of the house at full flow until cleared.

"This program is part of council's commitment to ensuring we continue to provide a safe, reliable and continuous water supply to the residents of the shire," Mr Giri said.

The water meter replacement program is expected to be completed by June 2015.
