We replaced a section of a trunk main, which connects our freshwater catchment in Poroti to our Ruddles water treatment plant before branching off in several directions towards town.
The section of the trunk main that was replaced runs from the treatment plant towards Otaika Valley Road, across several private properties (see the map above).
This area has experienced a number of slips in recent years, causing leaks in the existing concrete-lined steel pipe, which we have been repairing as needed.
As the existing pipeline was installed in a slope, there was a significant likelihood that slips would cause further damage to the pipe, so we replaced this section using a PE crack-resistant pipe, which is more durable and flexible.
