Over the last decade, demand for spring management has increased as traditional spring sources have started drying up or becoming contaminated. In response, communities, NGOs and state agencies began dedicated spring protection programmes. In the Himalayas, the State of Sikkim and organizations such as Central Himalayan Action and Research Group (CHIRAG) and People Science Institute (PSI) started identifying and protecting spring recharge areas around 2007. The difference between these programmes and many other previous efforts is that they went beyond supply-side improvements to focus on the use of hydrogeology to map springsheds for targeted interventions.
The Advanced Centre for Water Resources Development and Management (ACWADAM), a research and capacity-building organization comprised of hydrogeologists and other experts began lending their expertise and building capacity of stakeholders. ACWADAM provides technical support, training and materials in hydrogeology to all network partners as well as others in India and the region. Similar programmes began independently in most of the mountain regions of India. Arghyam, a funding organization that was supporting many of these programmes, noticed that these disparate initiatives shared commonalities despite geographic diversity. They thus organized and funded a meeting of these various organizations in June 2014, and the Springs Initiative was born.
The springs initiative aims to tackle the current water crisis and to ensure safe and sustainable access to water for all, by promoting responsible and appropriate management of aquifers, springsheds, and watersheds and conserving ecosystems in partnership with communities, governments and other stakeholders.
This presentation has been developed as a part of the springs initiative to promote an understanding of springs and their role in mountainous areas.
3. Springs are indicated by locations or points on the
ground surface, where water from beneath the
ground emerges onto the surface.

What are Springs?
A spring may be considered as
an ‘overflowing aquifer’
Springs represent ‘natural
ground water discharge that
feeds streams and rivers, often
making such streams and rivers
perennial…
4. Forms of Springs
Point Source Wetland Seep
Springs vary in size, type, location; often remote and difficult to access;
and vary in discharge through seasons
It is crucial to identify the type of spring in order to understand how they behave
in space and time
7. What is Watershed?
Watershed is an area which is
bounded by a ridge area from
all sides and drains out through
a common point
Watershed boundary

11. Springs and aquifers as commons…
Springs may emerge at given point
on any land parcel but the aquifer
that provides water to the spring often
extends below many such land
parcels….
The relationship between a spring, the
aquifer system below and the watershed
above define the ‘springshed’…

14. Springshed Development – Principles & Practices
Regenerating underground seepage
through engineering, vegetative and
social measures in the spring recharge
area
Principles:
• Increase Time of concentration
• Increase Infiltration
• Reduce Soil Erosion
• Improve Water Quality
• Promote Equitable Water Sharing
Practices:
• Trenching (SCT and CCT)
• Treatment of Drainage Channels
• Small Check Dams/Gully Plugs
• Vegetative Measures
• Social Fencing

33. Way Forward
• Village level water security planning based on water budgeting, spring
recharge activities, and capacity building of institutions.
• Introduction of water efficient technologies like SCI leading to more rational
ground water use.
• Creation of a cadre of para-hydrogeologists equipped to extend science
based springshed development in the region.
• Sanitary protocols for recharge areas leading to access to safe drinking water
and reduced health risks
• Community based monitoring of spring discharge and water quality to ensure
ownership and sustainability
• Strengthened village level institutions for managing springs in a sustainable
and equitable manner.
• Monitoring of impacts including access to water, biomass availability, soil
conservation and enhanced livelihoods.
• Documentation of scientific database and hydrological modelling for
planning springshed development in other areas.
Community's involvement helps managing groundwater (springs) as a common
pool resource
