Irrigation is the backbone of the Indian economy which is the cornerstone in Tamil Nadu agriculture development on which the livelihood of more than 60% of the population is depending on it. In Tiruppur district, Tamil Nadu, Amaravathy Dam was constructed across the Amaravathy river during the year 1953-58 for the benefit of irrigating the 22116 ha of irrigation land and basic domestic water needs in Tiruppur and Karur district. Amaravathy Dam is a composite structure made with both earthern type and masonry types dam. The dam was in service for the past 7 decades. So, the dam has been affected by seepage water through dam structures. Rehabilitation of structures in dam components is the need of the hour. Seepage is the main problem in the masonry portion of this dam and chokage in drainage systems. Repairing or rehabilitating the dam structure will enhance the life and durability of the structure. Reconstruction of chute and toe drains is also considered as effective. In this article, detailed study has been carried out to control the seepage and chokage problems in the dam structure, methods, like reaming, epoxy coating and injection grouting are followed.
