Central Design Directorate was established at Lucknow in the year 1961 for the specific need of undertaking the designs of major hydro projects. The designs of Ram Ganga multipurpose project, Rihand Dam, Obra Dam and Yamuna stage-I, Sharda Sahayak Project, Narora Barrage and Lower Ganga Canal Projects were completed sucessfully without seeking any help from any outer agency. To facilitate the works of Tehri Dam Project a Design Circle was transferred from Lucknow to Roorkee in the year 1971.
To cater the need of new multipurpose projects which were coming up for execution, particularly in the Yamuna and Ganga Valley located in the central Himalayan region, presently in Uttranchal, were also assigned to this circle resulting in the creation of Irrigation Design Organisation by expanding the only one Circle to ten Circles under two Chief Engineers in the year 1978 at Roorkee.
The Irrigation Design Organisation has been serving the state for the last three decades by undertaking the planning and preparation of efficient and econimical detailed designs and construction drawings of various multipurpose, hydroelectric and Irrigation projects with the help of well established infrastructure based on modern techniques.
The Organisation to day has a well established base in the field of design of concrete gravity dams, earth and rockfill dams, Roller compacted concrete dams, surface and underground powerhouses, Surge tanks, Pressure shafts/penstocks, Intake and Sedimentation Chambers, Hydraulic gates, Prestressed Concrete bridges and Aqueducts, Barrages and cross-drainage works and canal works. The organisation is also rendering consultancy services to UP Mini and Micro Hydel Corporation.
Having served the country very well for three decades, this organisation has a well established base in the design of:
– Concrete Gravity Dams
– Earth and Rockfill Dams
– Roller Compacted Concrete Dams
– Surface and Underground Power House
– Surge Tanks / Tunnels
– Penstocks / Pressure Shafts
– Intakes and Sedimentation Chambers
– Various Types of Hydraulic Gates
– Prestressed Concrete Bridge and Aqueducts
– Barrages, Gates & Hoists
– Cross-Drainage Works
– Canal Works
|Main Designs Carried Out:-
The design works of several multipurpose and hydroelectric projects have been successfully completed during the last three decades at Design Organisation. A few important projects are :
Yamuna Hydroelectric Scheme Stage-I
Commisioned in 1965, it comprises a 576.5 m long barrage across river Yamuna at Dakpathar to divert 200 cumec water through a 14.3 km long power channel to the two power houses at Dhakrani (33.75 MW) and Dhalipur (51 MW)
Yamuna Hydroelectric Scheme Stage-II
A 60 m high and 155 m long concrete dam at Ichari to divert the water of river Tons through 7.0 m dia 6.2 km long tunnel to 240 MW underground powerhouse at Chibro. Tail water is further taken through a syphon tunnel to 120 MW surface powerhouse at Khodri.
Ram Ganga Project
This multipurpose project comprises 127.5 m high, earth and rockfill dam across river Ramganga at Kalagarh and 198 MW power house at the toe of dam. The tail water is diverted into 84 km long channel to feed Lower Ganga Canal and Ramganga Canal system.
Maneri Bhali Hydroelectric Project Stage-I
The project comprises 39 m high concrete dam across river Bhagirathi, 8.6 km long tunnel and 90 MW underground powerhose.
Garwhal – Rishikesh – Chilla Hydroelectric Project
A 141 m long barrage near Rishikesh diverts the water of river Ganga through 14.1 km long power channel to Chilla surface power house of 144 MW. It was commissioned in 1981.
Khara Hydroelectric Project
The tail water of Kulhal powerhouse is utilized through 13 km long power channel and 4.1 km long head race tunnel to generate 72 MW at Khara power house.
Upper Ganga Canal Modernisation Project
The project comprises construction of a new canal of 370 cumec capacity parallel to the existing approximately 150 years old Upper Ganga Canal, including many cross drainage works mainly Solani and Ratmau Aqueducts. Radial gates for cross drainage structures have been designed in this organisation.
Ganga Barrage Kanpur
To cater the present and future requirements of water of Kanpur, 617 m long barrage and a prestressed bridge have been constructed.
Maneri Bhali Hydroelectric Project Stage-II
It comprises 81 km long barrage across river Bhagirathi at Uttarkashi, 16 m long 6 m dia tunnel and a surface powerhouse of 304 MW.
Tehri Dam Project
This multipurpose project comprises of 260.5 m high earth and rockfill storage dam across river Bhagirathi and under ground power house of 1000 MW in phase-I and another 1000 MW in phase-II.
Detailed design of diversion tunnels and preliminary design of all other works were completed before handing over the project to Tehri-Hydro Development Corporation.
