The canal on the Southern bund of the Vavunikulam tank is one of the three major canals that take water to the surrounding fields from the 40,000 acre reservoir. The canal which carries water to the Thunukkai area was found to be in need of repair before monsoons begin. Taking the lead, troops under 65 Division together with members of 9 farmers' associations renovated the 20 km canal. More than 2,650 acres of land is put under the plough from the water of this reservoir during both, 'Yala' and 'Maha' seasons. Regional irrigation and state officials also provided support to this community empowerment initiative of the Sri Lanka Army.
