Foreword
In pursuance of the Water (Prevention
and Control of Pollution) Act, 1974 and the Air (Prevention and
Control of Pollution) Act, 1981, the industrial units are required
to install effluent treatment plants {ETP) and emission control
systems {ECS) for complying with the prescribed standards.
Based on survey conducted by the Central Pollution Control Board
(CPCB), an inventory of water polluting industry and status of effluent
treatment plants was brought out in 1985. The survey revealed that
out of 4054 units, in large and medium sectors, 2076 units (51 %)
had installed appropriate measures for effluent treatment before
discharge.
Over the years significant developments have taken place in terms
of industrial growth and pollution control initiatives. To take
a stock of the present status, CPCB carried out coun- try-wide survey
for inventorisation of large and medium scale industry vis-a-vis
particulars in regard to installation of effluent treatment as well
as emission control systems.
