The program will be carried out to remove natural sediment build-up to assist delivery of clean water to consumers.

The council said the 2019 program proved successful until it was suspended because of drought conditions impacting the town's water supply and the logistical implications of attempting to capture the flushed water.

The delay in carrying out flushing means there's an increase in the frequency of discoloured water being delivered to properties.

Discolouration of the water supply may occur during flushing and consumers are advised to check their tap water before commencing any washing or drinking.

The crews will not be undertaking planned flushing over weekends so this is the best time to complete any clothes washing during the works program.

Residents may need to run their taps for a couple of minutes to clear the pipework and they may also notice a pressure drop during flushing in their area.

Following flushing consumers may notice an increase in the smell and taste of chlorine in the water supply.

The flushed water will not be captured and reused because capturing water in tankers results in a poorer clean of the mains, increased total volume of water used and added costs.
