Sustainability of Water Supply in Hill Towns in the Himalayas
The Himalayas are often referred to as the „Third Pole‟. This appellation acknowledges the fact that after the two poles – North and South - the Himalayas with their snowfields, glaciers and perennial rivers are the largest reservoir of freshwater on this planet. Reassuring as it may seem, this appellation pales when one looks at the paradox of water supply in towns and cities across the Himalayas. Traditionally water supply in hill towns has been based on supply from natural springs, streams fed by springs, lakes and rivers. Over a period of time, increasing population, loss of forest cover, lower water availability from springs and streams have ensured that hill towns and cities face water stress especially during the summer season. Leakages in the distribution system and a drop in…
