INTRODUCTION

ILR / Inter-basin water transfer (IBWT)

y

a highly ambitious and massive projectunder debate.

y is one of the options to remedy spatial

mismatch in water availability and

demand.

yhuman-induced transfer of water from a

(surplus) basin to a distant (deficit) basin.

Dr K L RAO PROPOSAL (1972)

- GANGA ± C AUVERY LINK ± 2640 Km

- required large amounts of power (5 to 7

MkW) for lifting the water and had no flood-

control benefits.

CAPT. DASTUR PROPOSAL (1977)

- First canal 4200 km river in west to Brahmaputra

in east.

- Second canal 9300 km GARL AND canalcovering the central and south India.

-  After detailed examination, it was found to be

technically unsound and costwise repulsive.

NATIONAL PERSPECTIVE PLAN

(1980)y The GOI decided to set up a NWDA.

y After a detailed study of the earlier proposals,

topography, river network, water availability anddemands, it formulated a NPP for water 

resources development.

y T

he distinctive feature of this is that the transfer of water is essentially by gravity and only in

small reaches by lifts (not exceeding 120 m).

y This plan comprised of two components:

VERDICT BY SC (2002)y On  August 2002, Supreme Court ordered the

Government to complete the construction of the

ILR project in the next 12 years.y In response to this order, the GOI appointed a

Task Force comprising Scientists, engineers,

ecologists, biologists and policy makers to ponder 

over the technical, economic and eco-friendlyfeasibility of this gigantic project.

Stated Benefits

y

Flood Control and draught mitigation.y Additional irrigation: 35 m ha (about 25% of the

ultimate irrigation potential of the country)

y

Hydropower generation 34 000 MW additionallyyFood grains production boost

yMany cities will get additional water for daily

use.yNavigation

yTo meet water quality criteria in rivers as more

dilution of water would be available in rivers.

Issues to be addressed for 

successful

implementation of ILRy Its optimal design and management would

require large quantity of data from different

disciplines like Topography, soil, geological,hydrometeorological etc.

y On account of the large size of the projects,

skilled manpower needed for extensive fieldinvestigations and to prepare DPRs.

Contd«y Social and political opposition may arise

mainly when people assume that there will be

loss of valuable resources, land and water.y Opposition from environmentalists and climate

change.

y Political issues of who should spend or who

should reap benefits ?

y Time and expenditures.
