This study was carried out in the culturable command of Heran distributary which is one of the three pilot sites in the LBOD Stage -1 Project. The effects of surface and surface drainage system on water table were determined. The distributary irrigates about 6239 hectares and is serviced by drainage network consisting of 14 saline tubewells, 3 scavenger tubewells, and 5 surface drains. A network of 68 Piezometers is spread over the entire command to monitor the water table. The operational hours of saline and scavenger tubewells were recorded for Rabi season. The average operational efficiency turns to be 31% while the temporal coefficient of variability was 91% which shows inconsistency in operation. The tubewells pumped out about 2.34 million m3 which cost about Rs 0.5 million on the energy consumption. A total of Rs 793512 accounted for operation and maintenance cost. Five surface drains were also monitored and discharges for every month were recorded. A total of about 5.57 million m3 (tubewells and lateral flow) of saline water was disposed-off by these drains.The results further reveal that the tubewells operating at 4-hrs per day lowered water table up to 0.91 m from the ground surface. While, it required additional 8.5 hours per day to lower it down to 1.52 m depth, which is a minimum recommended requirement to cultivate the major crops. Findings of this study reveal that the tubewells should continuously be operated for a total of 12.5 hours a day. It was also observed that the existing operational hours plus maintenance cost about Rs. 10.36 million for the entire area with Rs.166/ha in a season doesn’t produce any profit as watertable level still remained at 0.91 m below the ground surface. However, the additional operation of 8.5 hours costs Rs 0.79 million. In this way, the total operational hours required only Rs 294/ha to bring the water table down to desired 1.52 m depth. Once, the water table drops to this depth then the operation should be rescheduled to control recharge rate only. This could only be possible through proper water table monitoring and farmers’ training in the area.
