Immediate Challenge
•
Puducherry is a cyclone-prone eco-fragile belt on the east coast of India, located at
an elevation of 15 metres above sea-level.
•
Puducherry is intersected by the deltaic channels of the Gingee and Ponnaiyar
rivers and other streams, interspersed with lagoons, lakes and tanks and a number
of tributaries.
•
Water scarcity is the biggest challenge facing the union territory, aggravated by
lack of appropriate water storage mechanisms.
•
Intrusion of seawater due to coastal erosion poses a threat to the area’s aquifers.
•
Annual per capita availability of water (200 MCM per year) is less than estimated
requirement and could be exhausted over the next five years.

Activating Rainwater Harvesting Systems
•
Efforts have been made to store surplus rainwater in canals,
ravines and rivers by way of constructing small bed dams or
regulators.
•
These rainwater harvesting systems have been designed based
on hydrogeology, soil condition, rainfall and run off.
•
All public buildings in the union territory have been equipped
with rooftop rainwater harvesting systems.
•
Other solutions that have been implemented include reuse of
waste water and making necessary amendments in the
Puducherry building bye-laws and zoning regulations.

Rehabilitating Water Tanks
•
Around 84 tanks used for irrigation have been rebuilt to
increase their water holding capacity from 45 to 75 MCM.
•
Operation and maintenance of the tanks and water courses is
overseen by an elected body of local farmers.
•
To control and regulate the exploitation of groundwater in the
union territory, the Pondicherry Ground Water (Control and
Regulation) Act (2004) has been brought into action.

Constructing Check Dams
•
A total of 25 check dams have been constructed across
the rivers of Puducherry.
•
A check dam has been constructed at the infall point of
the Bay of Bengal to arrest the extension of backwater;
the water stored upstream for groundwater recharge and
water quality improvement

Way Ahead
Repair and restoration
of 52 ponds and tanks
and village ponds is
planned by the
government under
National Adaptation
Fund.
Technical assistance in
terms of capacity
building, monitoring and
data collection on key
hydrogeology projects
has been extended by
World Bank.
A Climate Change Cell
will be put in place to
effectively plan,
monitor and implement
select climate change
mitigation and
adaptation activities.
An Integrated Coastal
Zone Management Plan
proposal has been
submitted to Ministry of
Environment, Forest
and Climate Change,
Government of India.
