Revitalization of System H (Kala Wewa)
Description - System H is one of the first irrigation Systems to be developed under Mahaweli Development Program of Sri Lanka with diversion augmented from Mahaweli Ganga. It has incorporated already existed ancient Kala Wewa Scheme and several Small Tank Systems and extended the cultivated area. However, last several years this System is facing water scarcity issues due to several reasons. While the System H is under difficulties, downstream Rajangana reservoir is spilling regularly, meaning excess drainage water from H area is more than its water holding capacity. In this connection IWMI has launched a research project to revitalize the irrigation in this area. Research will assess the additional water resources flowing into the Right Bank Canal from the northern bank catchment and groundwater situation in the tail-end areas of the water distributary (D- Canal) system. Also, it is planned to establish the connection between fluctuating canal water supplies and the groundwater levels. Expectation is that this will enable part of the System to rely on conjunctive use of water. From elsewhere in the country and world, it is known that groundwater irrigation has made a silent revolution in the rural areas, enabling poor farmers to grow high value, market oriented crops and improve incomes. Conjunctive use will save water in the System for other needs including diversions to Anuradhapura City needs as well as reduce the spillage at downstream Rajangana reservoir.
