The project is aimed at alleviating the pressure on the local biodiversity of plants in the new settlement area of the village of Lapaha. Lapaha is one of the largest and oldest settlements in Tonga. It is still in expansion to this day. The area of which the project is based is a newly settled area whereby the local dense native forest had been cleared for. In the same area of this newly settled place lies the groundwater lens which supplies the entire village. There is a growing concern for the health of both the community and its surrounding environment. This project hopes to address these concerns by supplying rainwater harvesting systems to the household in hopes that the community can therefore be able to replant native forest trees in their allotments and surrounding areas to replenish what had been taken down. This in turns helps the community with their water management system which indirectly raises awareness on the health concerns of the settlement on top of the water lens.
