Pipe upgrade almost done
With nearly 5km of new pipes installed over the last 12 months, the upgrade of central Taupo¯’s water system is just weeks away from completion.
The original concrete pipework that was installed in the 1960s was reaching the end of its life cycle, and so a comprehensive renewals programme has been underway. New high-density polyethylene pipes with a rated useful life of 100 years, nearly double that of the original concrete pipes, have been installed, as well as new high pressure mains valves. Operations manager three waters Kevin Sears says the upgrade to the water main system means the central business district has a more dependable supply system that will last for generations.
“The new high-density polyethylene pipes are a lot more robust than the old concrete ones, so they not only last longer but are less prone to leaks, and the modern technology in the new mains valves also gives greater durability and resilience. The upgrade process has also meant we have been able to fully map where all these services are. The records we had from the 60s were not completely accurate, with some valves incorrectly shown in the system, so it’s great to not only have a new system in place but to have a clearer picture of our infrastructure. “This has been a big project, and we are grateful for the patience the community has shown throughout it.”
The final section of the central business district is the Spa Rd area, which has had numerous localised water shutdowns over the last few months as the new mains were installed.
Works there should be completed within weeks.
