| Abstract | To achieve the water pollution control, various countries of the
world have adopted different approaches so as to suit their local
and socio economic conditions. As water pollution control is a
social obligation, statutory intervention is essential through
l egislation and various standards.
A system of l egislation and a set of standards lead to effective
water pollution control . The main objective of the present study
is to compare adopted/proposed standards and legislation in
the area of water in Japan, Netherlands , Pakistan, Sri Lanka , Thailand, We st Germany.
Carrying out a comparative study on water pollution
control systems in different countries give a clear picture on
the effectiveness and failure of each system.
The water pollution control systems considered in this
research are Control authorities, Effluent control system, Waste
water charging system, Punishments, Water charges , and Sewerage
constru ction. Comparison of Industrial Effluent Standards
{disch arge in to water streams) j_n different countries was
carried out at last.
The study conclude t h e most s u itabl e system of control of water
pollution in developing countri es is partially decentralized
system. In developed countri es it is advisabl e to implement
decentralized system. Most suitable system of effluent control
for developed countries is mass control system with licensing
system. If it is not possibl e for the whole country at least for
the most polluted regions the system should be introduced . But
for developing countries it is better to introduced concentra- tion control with licensing system. In developed countries, to
control the water pollution it is advisable to introduce effluent
charges. But in developing countries not advisable to introduce
efflu ent c harge s for the time being. Punishments is applicable
to developed as well as developing countries. Water c h arges
s hould be increased gradually in developed countries to reduce
water pollution. This can be practiced in developing countries
by introducing l esser charges for water. Sewerage systems with
terminal treatment plant s hould be promoted in developed as well
as developing countries to reduce water pollution. In developing
countries standards should be imposed for the most important
water uses in the country or region. These standards values
should be based on the "Best Practicable Technology" in order to
financial burden on the industry. |
