Central Coast Water relined more than 245km of sewer mains across the region in the last financial year; 2021-22.
The organisation repaired 308 leaks across 1,000km of water mains, saving more than 870ML of water.
And it completed an inspection of the Mangrove Creek Dam Diversion Tunnel using robot technology.
Central Coast Council Water and Sewer Director Jamie Loader said that only two 10mm defects were identified after 40 years of service.
“This is quite a remarkable result for a piece of infrastructure over 40 years old,” he said.
The defects were repaired and the tunnel refilled.
Mr Loader has released the Council’s Water and Sewer Performance Report for 2017/18 – 2021/22.
Mr Loader said the report shows a baseline of the current performance.
He said the organisation will be working with the community to identify future performance metrics to ensure “we are reporting on the things our community values most”.
The move comes after IPART recommended in May, when it approved the Council’s water rates rise, that Council:
- Publish some performance measures and information
- Develop a set of performance measures that match the community’s preferences and expectations.
Council had to publish the data by the end of September and is now working on an implementation plan for the commitments it gave to IPART about performance, accountability and transparency improvements.
This means Council will publish an implementation plan by the end of October and then its first annual performance report is due in a year’s time.
In the meantime, it will engage with the community to develop an “outcomes based reporting framework reflecting community preferences”.
In May, IPART set the maximum prices for Central Coast Water that saw typical household bills increase by about 17% (or about $183) to $1,242 on 1 July 2022; and then increase by 6%, 8% and 1% (plus inflation) over the next 3 years.
The performance review also noted that Council refurbished ageing vacuum sewer pots at St Hubert’s Island and Davistown, resulting in a reduction in the number of service disruptions across both suburbs.
