Odisha govt to recharge rain water harvest in drought prone blocks
The innovation of some retired Odia engineers regarding subsurface recharge through rain water harvest management will be implemented in nearly 50 drought prone block in Odisha this year.
The new technique has proved successful in 10 blocks of 6 districts.
State Chief Secretary Jugal Kishore Mohapatra who reviewed the techniques and its application in a high level experience sharing discussion has advised to replicate the technique in 40 -50 drought prone blocks during this year. Mr. Mohapatra has said that the method to be successful over a large area needs intensive awareness of people and meticulous training of the implementing engineers. The department of water resource and Watershed Development Mission have been advised to take up intensive awareness activities on the value of rain water and benefits of harvesting it at subsurface level. It has also been decided that the engineers implementing the project will be trained through direct field exposure. The Odisha Watershed Development Mission has been advised to coordinate and monitor the project of replication. The experts opined that one 20 hectares Water Harvesting Structure (WHS) can at best hold maximum 17 per cent run off water from a watershed area of 500 hectares. The ground water recharge also gets limited through surface storage, because the reservoirs get silted up very soon which prevent significant seepage down to the subsoil.
In response to this situation, the group of engineers named as BB Consultants, led by Engineer Banamali Naik explained the technique, its application, possible cost involvement and outcomes.
He said the observation and experimentation over a long period of time, has discovered the technique of storing water at subsurface level. This subsurface level storage will be within 10 meters of surface level, from which vegetation can source the water, wells will be recharged, canals will get water and such storage will also add to moister level of the soil. The Engineer claimed that this is a low cost technology in which the investment per hector will come between Rs.15,000- Rs20,000.The technology has been piloted in the blocks like Tarabha in Subarnapur district, Maneswar in Sambalpur disrict,Barkote in Deogarh, Ghatgaon and Patana in Keonjhar, Padmapur, Paikamala, Bhatli and Jharbandh in Bargarh and Banapur in Khordha district. The application of the technology has yielded targeted benefits,Mr.Naik said adding that these piloting have been done through Government agencies like Western Odisha Development Council, Western Odisha Rural Livelihood Project, Integrated Watershed Management Project and Chilika Development Authority.
Application of the technology have also been facilitated through NABARD and other corporate agencies in Bansapal and Ghatgaon block of Keonjhar district, Thakurmunda block of Mayurbhanj district, Mohana of Gajpati and Hinjilikatu block of Ganjam district.
