As per world bank report
60% ground water is used for irrigation and Agriculture and 80% in Rural and
Urban Areas.
Today 29% ground water blocks are in Semi critical/critical condition and by
2025 60% will be in critical condition .
Further reduction due to climate change.

NEED OF THE HOUR…..
Appropriate management of water resources and
waste water
Municipal Authorities need to realize the problem of pollution of water bodies and pay attention to
their liability to set up sewage treatment plants in cities and towns to prevent this pollution. This
activity requires to be recognized as one of the most important indicators of overall development
of the Country
Urgent need to increase sewage treatment capacity and
its optimum utilization and upgrading and expansion of
existing capacity
Augmentation of treatment plants with tertiary treatment units to enable utilization diversion of
treated sewage for irrigation of crops not eaten raw. Improvement in bacterial quality of remaining
sewage to be used for irrigation of sports fields and public parks or that has to be discharges into water
bodies due to unavoidable circumstances

Policy Recommendations
Enforcement of Policies:
Stringent enforcement to ensure compliance with norms by Municipalities
Penalizing and Widely publicizing municipalities for noncompliance.
Incentive mechanism linked to central fund allocation could be implemented.
Tariff adjustment:
STW should always be priced lower than freshwater supply to encourage its use.
Town planning:
STW reuse should be an integral component while planning new cities, townships, industrial
areas and special economic zones.
Land for STPs and separate pipelines for freshwater, sewage and STW should be developed.
Building codes should mandate dual pipelines to carry STW and freshwater.
