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 completed and commissioned in September 2024. Remaining work is a programme of council upgrades (Motueka and Tākaka wastewater, Waimea Plains drinking-water treatment and network interconnections) delivered through the councils' long-term plans rather than a single defined scheme. No combined budget is set; the ~$450m figure is indicative only.
