A follow-up to the GARLAND Canal Scheme as originally proposed by Capt. DINSHAW J. DASTUR and the recommendations thereon by Col. P.L.N. CHOUDARY , AVSM in 1977.
“A solution to the problem of drought and flood that affects our Country”
Our Country suffers intensely under a recurring annual cycle of floods and drought which costs the Country dearly both by way of damage of crops and property and even more tragically so by way of loss of lives and live stock.
Over the years many schemes have been suggested for ameliorating this situation and quite a few schemes have been put forth to eliminate such problems altogether.
Some of the smaller amelioratory schemes have even been taken up despite the protests of well meaning but short sighted, so called environmentalists and social activists, and have over the years proven their worth. However the major schemes which are aimed at eliminating the problem have received some consideration but have not been taken up for implementation.
Of such schemes two are of National scope and deserve much greater consideration.
The National Water Grid – (Ganga to Cauvery link) as proposed by Dr. K.L. RAO
In 1972 a team of U.N Experts had this to say on this Project.
“India’s national economy in its development and growth will be confronted with the problem of increasing scarcity of water within the next thirty years. From basic compilation of future water demands and water yields it becomes evident that by the year 2000 or so the NATIONAL WATER GRID will be a vital necessity. No time should be lost to start the very complex and difficult investigations today, so that plans will be matured and prepared in due time and the facilities will become operative when the need will have come”.
This scheme has the drawback of requiring considerable power to lift water from the Gangetic plains upto the Deccan Plateau. Also, though it has the advantage of using existing water ways as far as possible and thus be less costly, it does not have the all encompassing scope and comprehensive effect of another brilliant suggestion on the development and utilization of India’s water resources –
The Garland Canal scheme by Capt. DINSHAW J.DASTUR.
The Garland Canal Scheme envisages a Trans Himalayan Canal extending into an Eastern Himalayan Canal at a height of say 1000m above sea level and another Deccan Garland Canal consisting of a Central Plateau Garland Canal and the Southern Plateau Garland Canal at a height of say 500m above sea level. The exact alignment to be arrived at after proper evaluation of all parameters both economic and geographic.
These two Garland Canals would be connected via suitably sized closed aqueducts, at their closest point, to allow transfer of water from the higher canal to the lower, operating on the siphon principle and thus instead of needing power it would allow power generation. World Bank studies had proved the concept of a water flow within canals even with zero gradient.
In Oct 1977 in the article published by the Economic Times, Col. P.L.N. CHOUDARY, AVSM drew on his considerable experience of building roads in the Himalayas under the Directorate General of Border Roads and in setting up and organizing camps for the NCC and ACC Cadets who undertook road construction works in Andhra Pradesh as social work, and took up successfully the task of saving the BHAKRA DAM in 1959 for which he was awarded the AVSM, and discussed the feasibility of the Garland Canal Scheme as suggested by Capt. Dastur , and indicated how it could be made more comprehensive and recommended the lines on which it could be executed. This more comprehensive scheme he called the ‘GRAND IRRIGATION AND POWER SYSTEM – GIPS’. (See Annexure)
