 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.
Waste Water Issues
 Over-exploitation of Groundwater hampering Sustainability

 A widening gap between irrigation potential created


and utilized
 Grossly inadequate maintenance of existing
irrigation infrastructure
 Wastage of available resources
 Under-utilization of available resources

 Natural water bodies and drainage channels


 Encroachment
 Diverted for other purposes
 Blockage of Groundwater recharge zones

 Growing pollution of water sources, especially through


industrial effluents is
 Affecting the availability of safe water
 Causing environmental and health hazards
 Heavy pollution of rivers, devoid of flows detrimental to aquatic ecology, cultural needs and
aesthetics.

NEED OF THE HOUR…..
 Appropriate management of water resources and
waste water

 Create awareness and consciousness about the overall


scarcity and economic value of water and the need to
avoid its wastage and inefficient use.

 Good water management with the aid of scientific


planning, utilization of modern technologies and
round-the-clock monitoring through information
technology

 Adequate addressing of Issues related to water governance with settlement of Inter-


regional, inter-State, intra-State, inter-sectoral disputes in sharing of water to enable optimal
utilization of water and Ensuring a holistic and inter-disciplinary approach to water related
problems by Central and State Governments and Local Authorities

 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

 Prevent pollution of water bodies by proper Sewage


treatment and Recycling and Reutilization of treated
sewage ; Sharing of revenue Generated by selling
treated water with local municipal bodies

 Stringent mandatory policies for the operation and


maintenance of existing plants and sewage pumping
stations conforming to the general standards
prescribed under the Environmental (Protection) Rules
for discharge into streams.

 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

 Replenishment of Groundwater by recharging groundwater with treated wastewater

Implementation of CPHEEO Guidelines for Sewerage and
Sewage Treatment
 DPR must be prepared as per the Guidelines given in the Manual on Sewerage and Sewage
Treatment published by CPHEEO, Ministry of Urban Development incorporating the under
mentioned details for technical appraisal and clearance:-

 Alternate sewage treatment options and choice of suitable option,


 Unit operations of the sewage treatment option chosen giving due weightage to
economize the capital as well as O&M costs with possible bye-product recovery.
 Recycle and reuse of treated effluent for various beneficial nonpotable uses,
 Proposal, if any, for use of manure, sewage gas etc. to generate revenue
 The proposed plant shall be designed according to land availability, power
consumption and effluent criterion.
 The Treatment Technology related to water and sewage treatment should be kept
open at tendering stage. This will ensure selection of most suited technology at
tendering stage itself after proper evaluation in respect of power
consumption, O&M, reuse, land requirement including capital cost. However, for the
purpose of estimation in DPR, the estimated cost for a feasible treatment options may
be taken.
 The above Treatment Technology should be considered inclusive of “Operation and
Maintenance” by the technology provider which may range between 5 to 10 years or
more. This will create a guarantee by the project developer to perform in the long run
and maintain the stipulated effluent quality parameters before disposal.
Recycling ? Why ?
Recycling wastewater - A viable alternative to fresh water supply
 Water Scarcity due to Depletion in natural water
sources as a result of large amount of evaporation
during summer and large drawdown from
groundwater reservoirs

 Exponential growth of freshwater demand and


wastewater production due to
 Population growth
 Urbanization
 Changing lifestyle
 Economic growth and Industrialization

 Disposal of untreated waste water into limited


freshwater resources as water cannot be used
directly

 Wastewater stagnation contaminating


groundwater

 Recycling wastewater to the minimum level


required for its subsequent use is cost efficient as
compared to using frestwater for non-potable
uses

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.

 Mandate Sewage treated water (STW) Reuse:


 Industries requiring bulk water and located close to urban areas should be mandated to use STW
and not given freshwater linkage.
 Industries located further away from urban areas, should be mandated to reuse their own
sewage water to meet part of their own overall water requirement.
 Water authorities should facilitate reuse of STW by supplying raw sewage or STW at cost of
supply.
 Energy-neutral technologies mandated for sewage treatment plants

 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.
