In North-East Efate, Vanuatu, several communities are struggling with water supply due to the Takara Dam drying up. Oxfam and EWB New Zealand have partnered to work on designs to improve the situation.
Due to the Takara Dam drying up, several communities in North-East Efate, Vanuatu are struggling. To improve the situation Oxfam is looking at potential options, including installing a backup for Takara, by connecting the overflow of the Epule Top Tank (at a higher elevation 1.5km away) to the existing Takara Dam.
To ensure that there is enough water to recharge Takara Dam as well as supply Epule Top, the existing pipeline from Epule Top will have to be upgraded to increase its capacity.
Oxfam has completed a pipeline design and asked EWB to peer review it. From Oxfam's designs and survey, EWB have produced a simple EPAnet model for the purpose of verifying their design.
Our technical support team members worked together to evaluate Oxfam's design and produce a short technical memo with recommendations for this project.
EWB has completed our design review and made recommendations that improve the robustness and reduce the project costs. The Vanuatu Government, who are managing the construction of this project, have taken our suggestions on board. Procurement of materials and construction work will begin later this year.
Our Technical Support Hub links our community partners with NZ-based engineering professional volunteers for technical assistance on our projects and placements. The Takara Dam Project is an example of how NZ experience can assist communities in need.
