- 70. Best Practices Build awareness & empower community to: • Find & fix leaks • Identify springshed • Protect from fire, grazing, tree cutting • Limit nearby pumping (bores, wells) • Build/maintain spring box, prevent contamination
- 71. Empowerment
- 72. Field Survey
- 73. • Leaks a major problem • Up to 25% of supply lost
- 74. Shramdhan
- 75. Springshed Restoration & Recharge
- 76. Spring Box
- 80. Sub-surface Box
- 84. Nalla-box (sand dam) With livestock or wildlife guzzler
- 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
- 89. HUMAN FECES ON A SPRING BOX
- 90. Water quality of springs
- 91. • Conversion to surface water sources (i.e. blasting to make a spring cum well) • Results in contamination
- 92. Spring Restoration & Ecology • Springshed degradation • Restoration best practices • Ecological reference conditions • Importance to biodiversity
- 93. Spring Recharge
- 94. Misplaced wells can destroy springs Spring Recharge
- 95. Best case, healthy native vegetation Spring Recharge
- 96. Spring Recharge Loss of trees = less monsoon captured
- 97. Annual burning & overgrazing = more runoff Spring Recharge
- 98. Spring Recharge Continued pressure = soil loss & no recharge
- 99. Ecological Degradation • Anthropogenic fire • Over grazing • Fuel wood collection
- 100. CCT – Continuos Contour Trenches
- 101. Staggered Trenches
- 102. Farm Ponds
- 103. Loose rock dams
- 104. Tree planting • Survival rate is 10% • Protection from grazing & fire • Watering
- 105. NORTH ASPECT SOUTH ASPECT Is this ecosystem healthy???
- 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
