Objectives of the Waimea Community Dam
The Waimea Community Dam is a significant local infrastructure project to augment the supply of water and add to the sustainability of the region. Objectives of the Waimea Community Dam
- Sufficient water at our homes all year round
- Healthy Lee and Waimea Rivers with abundant fish and flora where we can swim and play

The three-year project began in early March 2019 with site works to create access to the Lee Valley site. This was followed by the burying of a mauri stone, a mark of respect to Papa the earth mother and a blessing bestowed on the site and the structure that will be located there.
The second phase includes construction of the dam itself. The concrete-face rock fill dam will be about 53m high, 220m long, and 6m wide at the crest. About 430,000m3 of rock will be used to build the dam or be recycled on site. This phase is expected to take about 18 months, finishing around October 2021.
Once the dam is in place, the reservoir will fill up naturally for several months, with the final commissioning in February 2022. The lake created by the dam will contain approximately 13 million cubic metres of water.
WWL is responsible for constructing Nelson Tasman region’s newest dam. This includes:
- resource consent compliance
- land and access rights transfer and management
- health and safety compliance and assurance
- environmental compliance and assurance
- optimisation of sustainability opportunities
- community and stakeholder engagement
- management of contracts required to complete the contracts, including construction, design assurance and cost assurance
The project is divided into a series of workstreams and the team structure is amended progressively to match the evolving requirements of the project through its lifecycle, and then as the dam is commissioned into ‘business as normal’ operation.
