Abstract: This study revealed that the losses of water from the three watercourses were 27.11, 25.85 and 31.25 on total length basis and the losses on 100 meter length basis were 3.62, 3.15 and 4.47 percent, respectively. The conveyance efficiency worked out to be 72.89, 74.15 and 68.75 percent, respectively. The main causes responsible for water losses were leakages from naccas, curves in the watercourse (No.3), high density of vegetation, problem of siltation, deposition of sediments, weak and un-compacted banks, lack of maintenance and holes made by rodents. Improvements suggested were lining, proper inlet structures and regular periodical cleaning.
