Staff were shown a manhole that displayed concrete corrosion, as a result of decades of exposure to hydrogen sulphide gas, and watched a demonstration of the final stages of manhole rehabilitation. The manhole had been cleaned and re-lined with a concrete product the previous day and PPS demonstrated how they apply the final protection step, by spraying with a proprietary product called Renoseal. This form of rehabilitation will extend the structures life by 25 years.
The process took approximately a day and there was no interruption to service for the adjacent homeowners. Trenchless pipeline relining was also demonstrated and it was a surprisingly simple and effective process.
At the user group meeting it was highlighted that a regional procurement approach could offer groups of Councils improved pricing.
