ORANGE City Council contractors will be pumping a white-coloured mist into the sewer main in central Orange over the next couple of weeks to ensure the pipes are in top condition.
The contractors, All About Pipes, will be working in a seven-block area south of Cook Park including Kite Street, Woodward Street, National Avenue and Hill Street.
Council spokesman Allan Reeder said the routine investigations could detect if downpipes were connected to the sewer system, illegal connections, missing or defective structures, blockages or breaks and broken seals on manholes.
The work crews will also ensure the current sewer diagrams and plans are accurate.
“At locations in each street and in backyards the contractors will open manholes and pump a white-coloured mist into the sewer,” Mr Reeder said.
“They’ll then look closely at downpipes and sewer lines in each property to check for signs of the mist escaping from the sewer.”
Mr Reeder said householders had been informed of the property inspections.
“Contractors will also knock on doors before they enter a backyard to complete the inspection,” he said.
“It’s not necessary for residents to be home at the time and only outdoor access to each property is required.”
Mr Reeder said residents could ask to see the contractors’ identification.
“If any problems are found, residents will be informed in writing,” Mr Reeder said.
If thee here are any access issues for the contractors, or problems such as locked gates or dogs in the yard, a letter will be sent to the home owner asking them to contact council’s customer service centre on 6393 8000.
