Concept and Approach

Contributors
Concept of Springshed Development
Springs are indicated by locations or points on the
ground surface, where water from beneath the
ground emerges onto the surface.
Points of
groundwater
discharge
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…
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
Regional Spring-scapes of Indo-Nepal Region
What is a Springshed ???
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
?
?
Classical watershed….
Ridge to valley approach…..
Watershed-1
Watershed-2
Concept of springshed , a springshed is a set of watersheds and aquifers that integrate
into a system that supplies water to the springs in the springshed.

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’…

Village-B
It also tied into the larger concept on groundwater
management: shift in focus needed – from sources...

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

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

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
