Innovative Management to meet Crop water requirement

2.1.3 Innovative Management to meet Crop water requirement As the system ensures equitable water supply, when needed, at the start of Rabi season, the WUA plans the area under different crops that can be irrigated with available water in the reservoir and accordingly the farmers grow different crops to suit the volume they will receive.
2.1..1 Guaranteed irrigation for Grape Water is managed in such a way that every shareholder is guaranteed to get water sufficient to irrigate one hectare Grapes. The annual amount of water required for grape planted, inclusive of evaporation and other losses is kept reserved and the surplus water is then utilized for other crops as decided by the WUA. This strategy enables them to switch over from traditional rain fed crop to high yielding Grape plantation and vegetables.

2.1.4 Adoption of the advance irrigation Like drip irrigation method The water received by the individual is then let in to their own well. The collected water is then utilized for irrigation with drip irrigation system. Due to adoption of the drip system the water is utilized efficiently and the farm yield is increased many times.

2.1.5 Assessment and Recovery made easy The engineer in charge will take the reservoir water level at the start and at the end of the season. The amount of evaporation and other losses is deducted and the volume of water content used by the WUA is assessed, with the help of area capacity table of the reservoir. He prepares the water bill and gives it to WUA. There is no need to measure the individual’s area or crop irrigated. After receiving the water bill, the WUA add the predefined additional charges in to the bill and divide the total amount by 115 i.e. number of shareholders, Prepares a bill of each group by multiplying the number of members in that group. The bill is given to the group leader. The group leader then collects the charges from his member and submits to the WUA. And then the WUA pays it to water Resources Department.

2.1.6 Efficient and conjunctive use of ground and surface water The farmers start the irrigation with the ground water available in to their well. The well yield get reduces in the month of December or January. At such time WUA takes the decision to deliver the water stored in the reservoir. Pumping hours per day of the main pump on the reservoir are worked out in such a way that the surface waterharvested in the reservoir will be available to irrigate one hectare of land of each shareholder, till the starts of the monsoon.

2.1.7 Multiple gains in farm income Due to assured and timely water supply the farmers able to raise the crops like grape and vegetables. Thus their farm income is multiplied in many folds. Per hectare average income is raised from Rs. 2500 to Rs. 93000.

2.1.8 Increase in farm produce per unit of water use The per hectare water use at the reservoir out let head is considerably reduced from 12778 cubic meter to 2742 cubic meter and thus the per cubic meter water productivity is increased from Rs. 1.96 to Rs. 33.91

2.1.9 Increase in utilization of Irrigation Potential Though the irrigation potential creation of this tank was 157 ha, the area irrigated was not more than 22 ha, But after implementation of the scheme the area irrigated is more than 287 ha. It is worth to note that out of the total 287 ha area, 112 ha. is perennial Grape crop.

2.1.10 Benefits to Government

The management is made very simple. Conflicts are reduced. Irrigation staff requirement is reduced, thus saving in wages of management staff. Assessment of water charges is made simple. Recovery of water charges is 100%. The irrigation revenue is increased from Rs. 5000 to Rs. 1 30 000 per annum.
