A wide spread mains flushing program will take place in Werris Creek by Liverpool Plains Shire Council (LPSC) this week.
The aim of the flushing program is to clean out any dirt, debris, iron and manganese build-up, and dirty water remnants from the water supply reticulation system.
LPSC water services manager Rod Batterham said residents might notice some small issues with their taps.
"Residents may experience a temporary drop in pressure during flushing. The process itself also creates a short term dirty water situation and discolouration may occur after flushing," Mr Batterham said.
"Residents are advised to check their tap water before commencing washing or drinking [as they] may also experience 'cloudy' water which can occur when air enters the water."
Mr Batterham said this would disappear fairly quickly when placed in a glass.
"If discoloured water is present, a short running of an outside tap, preferably the furthest from the water meter, to flush the consumers own system should suffice to clear the colour," he said.
The council will try to capture as much of the flushing water as possible into a water cart, which will then be used to irrigate grassed areas such as David Taylor Park.
Flushing water cannot be used on residents' lawns and gardens as the water will be expelled at force and could damage plants if directed onto them.
