Coliban Water has reported record low sewer blockages in the last year thanks to a dedicated program of sewer maintenance and preventative cleaning known as Stop the Block.
In a media release, executive general manager service delivery, Danny McLean, said Stop the Block campaign was launched in 2016, increasing investment to over $1 million each year to improve sewer performance and reduce service interruptions, overflows, and impacts to communities and the environment.
“In the last financial year, we recorded 18 blockages per 100 kilometres of sewer, which is a dramatic reduction since the 2013/14 financial year, where we recorded in excess of 60 blockages per 100 kilometres,” Mr McLean said.
“It’s also a reduction from 22 blockages per 100km in 2019/20 financial year.
“The 70 per cent reduction means greater than 3,800 blockages have been avoided in the last 7 years. This is a huge reduction in customer and environmental impacts. It’s also saving customers’ money on reactive sewer repairs and clean-up costs. That’s a real win for the community,” he said.
During 2020/21, there were record low blockage counts in several months, including in December and March, which contributed to an overall record low blockage rate for the year.
“We have been utilising closed circuit television (CCTV) to assess the condition of around 3,500 poor performing sewer mains throughout our region, which provides accurate information to drive our renewals program,” Mr McLean said.
