Bhubaneswar: Looking into the field level positive impact of the bridge-cum-water wire structures during different field visits, Chief Secretary, Suresh Chandra Mahapatra directed the Department of Works to scale up replication of the new-technology throughout the State. He gave this direction in a high level meeting held on digital mode from State Lokseba Bhawan wherein Principal Secretary Works Vir Vikram Yadav outlined the technological and administrative facets for discussion.
Reviewing the water holding capacity of the bridge-cum-water-wire structures piloted in some districts, Chief Secretary Sri Mahapatra said, “It is most cost-effective technology with multiple utilities like ground water recharge, raising the water level in river beds, irrigating the fertile land on both sides of the river etc. In some places, river front parks can also be developed as a public utility”.
Development Commissioner Pradeep Kumar Jena said that the check dam-cum-water wires had also no adverse effect on usual flow of water in the concerned river or nallah as it allowed the flow beyond 1.5 meter of height. Sri Jena added that the structures could be done through two different methods viz. automated gate provision, or plain water holding structure to the permissible height. Both the methods proved effective for our State.
Chief Secretary directed the Works department to identify the high level bridges in all roads under the departments of Rural Development and Works where such structure would be feasible. The department was asked to prepare a 3-year perspective plan for the purpose. Target was set to construct 1000 such bridge-cum-water wire structures in coming three years.
Principal Secretary Mr.Yadav appraised that around 49 bridges were taken up for such structures on pilot basis. Out of this, the structures under 12 bridges were completed. Major completed structures included water-wires under HL bridge over Iswarpal Nallah, HL bridge over Ramial river in Dhenkanal district; Cell Bridge over siding Pata Nallah, HL bridge over Fatkamal Nallah, HL bridge over Rajendra Jore, Bridge over Local Nallah on Dadpur-Rupra road in Kalahandi district; Bridge over Kanchi Nallah on State High way-19, HL bridge over Raigudi Nallah in Matyubhanj district; and. HL bridge over river Genguti on Dhamnagar- Sendhpur road in Bhadrakh district.
Further, Chief Secretary Mr.Mahapatra directed the department of water resources to the supply the stocked water for irrigation on both sides of the nallahs and rivers where such structures were completed through lift-point pipes. Horticulture department was asked to motivate the farmers for cultivation of vegetables and cash crops. The water could also be used for drinking water projects wherever necessary.
He also directed engineers of the Works department to complete constructions of water-wire structures in balance 37 bridges on war footing. These structures would come up in the districts of Angul, Dhenkanal, Jajpur, Ganjam, Keonjhar, Kalahandi, Bolangir, and Sundargarh.
Special Secretary Works, Manoranjan Mishra appraised the cost involvement in construction of I meter water-wire comes around Rs.1.5 lakhs. It can hold water level of around 1000 cubic meter. Water-ware under a thirty meter bridge could yield 30,000 cubic meter of water at a particular point of time. The structures also sustained the pressure of water during the monsoon.
