DACCA IRRIGATION

closed

The Dacca Narayangam Demra Irrigation Project has as its objective the pump irrigation of 16,800 acres, of which 11,900 acres will also be afforded flood protection and pump drainage. Water for irrigation will be pumped from the nearby Lakhya River. During the irrigation season the land elevation is above the river level and drainage would be by gravity. During the monsoon season the river level is higher than the land and drainage would be by pumping. The main works include an intake canal, a pumping plant and sub-station, distribution canals, drainage channels and ditches and the closing of bridges and culverts in the road embankments for flood protection. The main civil works consist of a pumping plant, irrigation and drainage system, flood protection works, major and minor structures, and land leveling and field borders. The Dacca Southwest Irrigation Project (Cr. S0008) would provide flood control, drainage, irrigation and internal navigation for an area of about 490,000 acres. The elimnation of flooding and the provision of irrigation would enable the use of fertilizer and improved varieties of rice and would therefore contribute to an estimated tripling of present rice yields in the project area.
