7. Why Springs?
• Water biggest
issue in local
villages
• Lots of
opportunity for
springs as
solution
• Grampari started
spring protection
programme 3
years ago
8. Map Credit: wikimedia.org/wikipedia/commons
• Now part of larger
initiative funded by
Arghyam to make
springs national
priority
• Other partners in
corners of India
• We are partners for
Western Ghats
22. Typical Characteristics
Discharge = up to 1,00,000 liters per day
Elevation = 50 to 1400 m above sea level
Geology: basalt, laterite or talus
Spring type: contact or fracture
23. Typical Characteristics
Uses: drinking, irrigation, temples, animals
Safe, sustainable source of drinking water
• Gravity-fed = no pumping cost
• Year round supply
• Water quality very high
27. Ecohydrologic Status
• Generally, declining discharge due to:
– groundwater exploitation
– ecological degradation
• Poor maintenance, mismanagement common
34. What we do know
• Springs found
throughout Western
Ghats
35. Karjat Area:
Elevation – 50 m
Flow – ~7 l/m
Use – irrigation
Status – disuse,
loss to bore wells
Pune Area:
Elevation – 700 m
Flow – ~10 l/m
Use – drinking
Status – loss to
bores, wells
Koyna Area:
Elev – 800 m
Flow – ~30 l/m
Use – drinking
Status – healthy in
unpopulated area
Panchgani Area:
Elev – 1200 m
Flow – ~9 l/m
Use – drinking
Status – loss to
bores, wells

41. Western Ghats
Modified from Molur et al. 2011
• Considered one of eight
top biodiversity
hotspots in the world
• Only 6% of the primary
vegetation remains
intact
*Myers et al. 2000
42. Western Ghats Watersheds
- Cover 9 states
- Direct water supply for
120 million people
- Indirect, >400 million

43. Hydrogeology
• Springs in Himalaya vs Western Ghats
• Groundwater & springs
• Local investigation of Akehgani
– Springs, aquifers & recommendations for recharge
& protection

85. Water quality of springs
• Contamination generally due to poor design in
harvest and storage
• Conversion to surface water sources (i.e. blasting)
• Surface water runoff
• Storage tank hygiene
86. Water Quality of Springs
• Water quality very good; min & max values
– Temp: 17 – 22 °C (winter)
– Ph: 7.3 – 8.3
– TDS: 35 – 160 mg/l
– EC: 70 – 320 mmho/cm
– Hardness (CaCO3): 30 – 140 mg/l
– Na: 2 – 25 mg/l
– K: 0 – 2 mg/l
– Ca2: 10 – 36 mg/l
– Mg2: 1 – 12 mg/l
– HCO3: 31 – 177 mg/l
– Cl: 7 – 14 mg/l
– Fe2: 0.4 – 0.7 mg/l *****
From Naik et al. 2000
• Only iron shows marginal excess
• Pathogens are rare at source (e.g. no fecals)
87. Typical spring box
• Installed in 1970s as drought
response
• Poor design & maintenance =
leaks, contamination
• Declining flow due to adjacent
pumping, ecological
degradation
109. • Freshwater biodiversity
dependent on springs
(plants, insects, fish and
other vertebrates)
• Many of the most
threatened species (large
mammals, fish &
amphibians) depend on
springs
• And these are some of the
most heavily used
ecosystems
