Lennox Head residents get that ‘sinking hole’ feeling
ON THURSDAY morning residents from Rutherford Street, Lennox Head found a sinkhole had opened up near their homes.
"Yesterday morning we received a report from the public that a sinkhole had formed in their road," Ballina Shire Council's operations engineer for water and wastewater, Russell Yelseth said.
"The sewer main that services the area had broken at a boundary shaft and filled with sand, blocking the main and causing the sinkhole."
The broken pipe is three metres deep and below the water table, making repairs difficult to manage.
Mr Yelseth said specialist crews and equipment will be arriving on Monday with work commencing on Tuesday and Wednesday to 'de-water' the sinkhole area.
"This is where we need to remove the ground water, dropping it below the water table at the point of the investigation," he said. "We will be continuously sucking the water out of the surrounding hole where we excavate. We will be digging three metres down near the pipeline to repair it."
Access in and around Rutherford Street during this time will be restricted.
Mr Yelseth said Rutherford St residents will be letter-dropped and advised about the work.
"The equipment is noisy but will not be used at night unless absolutely necessary," he said.
At this stage we will not be using the de-watering pump overnight and will plan the repair works accordingly .
