PROVISION FOR DRINKING WATER SUPPLY SYSTEM IN

MULTIPURPOSE AND IRRIGATION PROJECTS


3/16

Despite the National Water Policy adopting in

1987, giving top priority for allocation of water fordrinking purposes in the planning of irrigation and

multipurpose projects and also that the States having

recognised the same in their planning, it is felt that

specific guidelines are formulated and issued as to themanner of integration of the system for supply of

drinking water phys ically and operationally with ther::anal network, which would further facilitate in

'accelerating the process. With this in view, theProject Appraisal Organisation of Central Water

Commi~ion have prepared these guidelines which, it is

hoped, would prove useful.
