In-situ semicircular concrete canal sections were fabricated and laid down with a view to reducing water losses as well as to relieving acute water logging condition resulted from faulty canal design in 32 meter-long section of a main canal in Satrashia DTW scheme under Muktagachha Upazila in Mymensingh district. The situation was further deteriorated by the presence of Mymensingh-Tangail highway under which that canal passes through to the western direction from the irrigation unit. The format developed for fabricating this canal section was very simple, which could be handled very easily even by local skilled and semi-skilled labours. The cost per running meter of the section was Tk. 43.88 (25 percent of the cost of brick lining) and the water loss through it was only 0.002 lt/sec. Using this section, the water saving was 99.05 percent over the previous under capacitated semipucca canal. The introduction of this section replacing the earlier one in the scheme helped not only in getting rid of the water logging condition, the water distribution as a whole improved quite significantly.
