Abstract:
With the increase in population
centered around cities, and the improvemen
t in living standards, .there has
been a considerable upsurge in the
consumption of water, which necessarily
calls for extension of facilities for
distribution, purification and treatment
of water.
On the other hand, facilities are
required for control of floods which
occur in heavy rains, for supply of
industrial water which is indispensable
for expanding industry, as well as for
discharge of waste water from plants
and treatment of such water.
