Abstract/ Executive Summary:

A farmers’ managed DTW at Dhirasram, Gazipur was selected to conduct the study in Boro 1999-2000. A survey was conducted in January 1999 to document the existing water management practices in the DTW system for rice production. In Boro 1998-1999 this system was introduced there with a PVC cross (15 cm x 10 cm x 10 cm x 10 cm) and 400 m plastic pipe (10 cm dia). It increased the command area about 16%. But there were some problems to operate the system. To overcome those problems the design was changed. In the new design 2 m ( 20 cm dia), 18 m (15 cm dia) PVC pipe was used at the delivery end of the well. A PVC Tee (T shaped) (20 cm x 15 cm x 15 cm) was used to distribute the discharge. For distribution lines 15 cm dia plastic pipe was used instead of 10 cm dia plastic pipe. To protect the leakage in the pipe joint iron clamp was used.
