CCTV Inspection of Sewer Pipes Underway

Dec 10, 2013

QLDC contractors will use CCTV cameras to inspect the network of sewers under Central Queenstown following a blockage in Athol St last night.

Staff from Veolia Water removed pavers from two separate locations where they had become wedged in the pipes, then waterblasted the system to ensure it was clear, QLDC General Manager – Infrastructure and Assets Erik Barnes said.

As a result of the blockage, solid waste over flowed onto Athol Street, although only a minor amount of wastewater – estimated at between 100-500 litres – reached Lake Wakatipu via Horne Creek, at the southern end of Queenstown Bay.

The affected areas around Athol St, Horne Creek and the lake foreshore were all disinfected last night. Water samples were taken last night and this morning.

Mr Barnes said it unlikely that last night’s blockage had any relationship to a similar issue last Tuesday, which was caused by construction debris in sewer pipes in a different location.

“I don’t want to speculate on how the pavers ended up in the pipes, but we have arranged for a full inspection of the system under the CBD to check whether there is any other debris that could cause us problems,” he said.
