Evaluation of a traditional community water management structure in Yethadka village of Kasaragod district in Kerala

Traditional type of check dams in the Kasaragod district of Kerala, locally known as Kattas proved significant role in water storage and water recharging, which in turn help to meet the drinking water and irrigation requirements of the locality. A field study was conducted in Western Ghats region of Northern Kerala at Yethadka village to test the efficacy and financial viability of a temporary check dam established in a participatory mode. The cost-benefit analysis of the water harvesting system was also carried out to find out its financial viability and social acceptability. The studies suggested that the construction of Kattas ensures a reliable source of water for irrigation during summer months and also helps to increase the groundwater table. The analysis also indicated that establishment of such structure was not only financially viable but a highly attractive proposition, too for low cost harvesting and effective use of channel flows.
