GROUND WATER DEVELOPMENT MINOR IRRIGATION SCHEMES

These are capable of discharging 200 cubic meter per hour to irrigate and culturable command area of 40 hectares through under ground pipe lines emanating from an elevated distribution chamber. A large number of such structures are existing and are being operated by Govt. machinery. However as per policy of the State these type of structures are being handed over to the users for subsequent operation, management & maintenance.

These are capable of discharging 100 cubic meter per hour to irrigate and culturable command area of 20 hectares through under ground pipe lines emanating from an elevated distribution chamber. A large number of such structures are existing and are being operated by Govt. machinery. However as per policy of the State these type of structures are also being handed over to the users for subsequent operation, management & maintenance.

These structures are suitable for areas where water table is usually more than 7 meters below ground level and electrically operated submersible pump sets are required to be used for lifting water. These are capable of discharging 30 cubic meter per hour to irrigate an area of 4 to 6 hectares through open channels. These structures are installed in a cluster of 5 to 6 tube wells. It has been found that such structures can be managed very efficiently and economically by the users.

These structures are suitable for areas where water table is within 7 meters below ground level and water can be lifted with centrifugal pump sets run by electric motor set or diesel engines and thereby dependence on electricity can be avoided. These structures are suitable for the 6 Districts in the northern part of the State and part of Murshidabad District. Each of the tube well will be capable of discharging 30 cubic meter per hour to irrigate 4 to 6 hectares of culturable command area and it is possible to have 200% cropping intensity.
