Waimea Community Dam cone valve release

DAMWATCH ENGINEERING is pleased to announce the first operations of the dispersing fixed cone valve releasing, water from Te Kurawai o Pūhanga, the reservoir behind the Waimea Community Dam.
Water was released through the smaller of three permanent dispersing valves constructed to release into the Lee River.
DAMWATCH ENGINEERING is honoured to be an integral part of the team delivering this critical infrastructure to the Tasman area.


The smaller fixed cone valve has increased flow into the Lee River at a time when it is severely needed. We are pleased to be able to lift the river flow on Saturday and I thank our commissioning engineers, the contractors and wider team for getting this valve operational to release water, said Waimea Water Ltd CEO Mike Scott.

The Waimea Community Dam, a public private partnership between the Tasman District Council and Waimea Irrigators, is the first large dam to be constructed in New Zealand in 25 years. The reservoir will hold 13 million cubic metres of water to provide water security to the region.

Waimea Community Dam reaches full capacity

Te Kurawai o Pūhanga, the reservoir behind the Waimea Community Dam, reached its full capacity and the spillway commenced flowing on January 21.
DAMWATCH ENGINEERING is proud to be part of the team delivering important infrastructure to the Tasman area.


This is a momentous milestone for the project, and I thank all those involved in getting us to this point, said Waimea Water Ltd CEO Mike Scott.
The reservoir was blessed and named Te Kurawai o Pūhanga by Ngāti Koata in June 2023, in honour of Puhanga Hemi Tupaea (Ngāti Koata, Ngāti Kuia, Ngāti Toa), herself a “reservoir” of knowledge of Māori arts, crafts, music and tikanga.

Viet Nam New Zealand Dam Safety Project: Phase 3 Launched

Phase 3 of the Viet Nam-New Zealand Dam Safety Project was launched on 25 July 2023. The project is building capability and resilience within Vietnamese communities to manage the risk of dam failure. New Zealand Ambassador to Vietnam, Hon Tredene Dobson, and the Viet Nam Vice Minister for Agriculture and Rural Development (MARD), Mr Nguyen Hoang Hiep, were joined by project partner representatives to celebrate the launch of Phase 3 at a meeting in Hanoi.
Viet Nam has over 7,000 dams, many of which are in deteriorating condition. Supported by $7.5 million funding under the MFAT New Zealand Aid Programme, Phase 3 doubles the number of sites of the previous two phases of the project to a total of nine major dams in seven large river basins and more than 300 medium dams to provide improved safety for dams and disaster risk management for downstream communities.
The project team from DAMWATCH ENGINEERING, GNS Science from NZ, and local partner Thuyloi University is working with the Viet Nam Government, dam managers and downstream communities to develop dam safety solutions that can be delivered down to the local level. This includes the:

  • assessment of flood risks and upstream geohazards such as large landslides and earthquakes,
  • dam structural integrity,
  • flood consequence modelling (e.g., casualties, building damage) and
  • preparedness of downstream communities to respond if a dam fails (e.g., early warning systems and evacuation plans).

Phase 3 focuses on transferring best practice disaster risk management at the local level to enable communities to develop response planning appropriate to their needs. This includes integrating climate change impacts and social inclusion in local dam safety practices.

Waimea Community Dam Reservoir Filling Underway

The river diversion that allowed the 52m high Waimea Community Dam to be constructed was closed on 25 May 2023. The contractor Fulton Hogan-Taylor JV then constructed permanent plugs and installed isolation valves to allow reservoir filling to commence. Reservoir filling is now underway.
The dam, a public private partnership between the Tasman District Council and Waimea Irrigators, is the first large dam to be constructed in New Zealand in 25 years. The reservoir will hold 13 million cubic metres of water to provide water security to the region.
The reservoir will be filled in stages by keeping the water level at hold points for extended periods to allow for testing and engineering measurements. When it rains there will be times when water will need to be released to return the reservoir to a set level, and then when ready, the reservoir level will be built up to the next hold point. The objective is to have the reservoir full and dam commissioned by December, to provide shareholders and community with confidence ahead of summer.

Embankment Concrete Face at Waimea Dam wins Excellence Award

DAMWATCH ENGINEERING is very proud to be awarded in association with contractor Fulton Hogan-Taylor Joint Venture and client Waimea Water Ltd the Excellence in Concrete Infrastructure Award at the Concrete NZ Nauhria Industry Awards of 2023. This award was for the slipformed upstream Embankment Concrete Face (ECF), the waterproof component of the 52m high dam. The slipforming method of concrete placement on the sloping face minimised the need for joints in the final structure. The Concrete Face of a 300mm thick reinforced concrete slab comprising 800 tonne of reinforcement and 3,800 cubic metres of concrete, with PVC waterstops to seal panel joints.
