The building of two new reservoirs will provide a major boost to the District’s water supply, as work to strengthen drinking water resilience continues, says the New Plymouth District Council (NPDC).
Building work on the reservoirs north of New Plymouth kicks off this week and will add 9,000m3 of water storage to the district’s supply from 2022 – that’s about 36,000 full bathtubs.
New Plymouth District Mayor Holdom says a recent Berl report showed NPDC’s infrastructure spending was a key economic driver for the district, but more investment in core infrastructure was needed.
“We know our people are right behind our work to get our core infrastructure up to scratch, but there’s still a way to go,” says Mayor Holdom. “These two new reservoirs will make a real difference to our drinking water supplies.”
It’s estimated the two reservoirs will cost approximately $16-18 million, subject to earthwork and weather variables. They are being built on sites off Henwood and Mountain roads next to existing reservoirs and they will take about two years to complete. Drivers are being asked to cut their speed on sections of Henwood and Manutahi roads due to site traffic.
In 2018, NPDC committed an additional $44 million investment in water resilience over the next decade following ex-Cyclone Gita. Part of this money will be used in the new reservoirs projects. Other water resilience projects include $2 million for another water bore and treatment plant upgrades in Ōākura and a $7 million (approximately) project over several years, to improve Inglewood’s drinking water.
Drinking water: fast facts
- Each year we treat about eight million cubic metres of wastewater at the New Plymouth Water Treatment Plant.
- The plant provides water for 26,000 homes and business from Urenui to Ōmata – that’s about 90 per cent of the water for the whole district.
- There are 800km of pipes in the New Plymouth District.
- The district’s main water storage – Lake Māngamāhoe – holds about 10 days’ worth of water.
- On average we use 292 litres per person every day.
