WATER

Nelson Tasman Regional Water

Nelson City Council / Tasman District Council · Nelson

Regional water resilience for Nelson and Tasman after the 2021-2022 restrictions. The flagship piece, the Waimea Community Dam, was commissioned in September 2024. The rest is a programme of council upgrades, Motueka and Takaka wastewater, Waimea Plains drinking-water treatment and network interconnections, delivered through long-term plans rather than one defined scheme. No combined budget is set; the $450m sometimes quoted is indicative only.
