The unusual request comes as some of Orange’s oldest sewer pipes dating back to 1914 are given a new lease of life with PVC lining expected to help the pipes last for at least another 50 years.

Around two-and-half-kilometres of sewer mains are being inspected with cameras, cleaned and relined as part of the five week renewal program.

Residents in Clinton Street, Byng Street, Woodward Street, Hamer Street, Summer Street, Anson Street and National Avenue were notified of the work by letter from Orange City Council contractor Kembla Watertech.

While disruptions are expected to be minimal, residents have been told water may be redirected into the pan when the pipes are cleaned.

“Sometimes if you get a junction that’s close by water can shoot up in that area but it’s not very common,” Orange City Council supervisor Les Miller said.

“We had one a couple of years ago.

“It’s a safety thing to stop water from coming out onto the floor.”

Although the pipes were still functioning, Orange City Council’s water and sewer strategy manager Wayne Beatty said the condition of the old pipes was poor and access was difficult.

The PVC lining will be fed into the sewer through manholes to improve the pipes structure and sewer flow.

Mr Beatty said the contractors have been doing regular doorknocks in the area to ensure all residents are aware of the work.

“Discussion and consultation with people affected is the highest priority,” he said.

Although the work is designed to minimise digging and disruptions to backyards, so far workers have had to dig up lines around 10 times when they have come across a dead end, Mr Miller said, with all holes refilled with topsoil and gardens replaced.
