  2. 2. Water war of Cochabamba • The Cochabamba protests of 2000, also known as the Cochabamba Water War or the Water War in Bolivia,[1] were a series of protests that took place in Cochabamba, Bolivia's third largest city, between December 1999 and April 2000 in response to the privatization of the city's municipal water supply company Semapa. The wave of demonstrations and police violence was described as a public uprising against water prices.[2]
  3. 3. Cause of water war In Cochabamba • The tensions erupted when a new firm, Aguas del Tunari – a joint venture involving Bechtel and Suez Lyonnaise – was required to invest in construction of long-envisioned dthey had dramatically raised water rates. Protests, largely organized through the Coordinadora in Defense of Water and Life, a community coalition, erupted in January, February, and April 2000, culminating in tens of thousands marching downtown and battling police. One civilian, Victor Hugo Daza was killedam
  4. 4. Impact of the water war • In Bolivia, the Water Revolt ignited a chain of events that provoked historic political and social change. For almost two decades Bolivian economics had been dominated by the Washington Consensus, market-driven policies pushed by the World Bank and the IMF and carried out by national leadership that was fiercely obedient to those policies. The Water Revolt shook those arrangements to their core.

  6. 6. What is rainwater harvesting? • Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc.. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation
  7. 7. Benefits of rainwater harvesting • To harness good quality water resource now being wasted • To prevent groundwater depletion • To augment the expensive piped water supply • To save expenditure on water • To prevent soil erosion and urban flooding • Inexpensive and simple technology • Aids ecological conservation
  8. 8. Rain water harvesting • Rainwater harvesting refers to structures like homes or schools, which catch rainwater and store it in underground or above-ground tanks for later use. One way to collect water is rooftop rainwater harvesting, where any suitable roof surface — tiles, metal sheets, plastics, but not grass or palm leaf — can be used to intercept the flow of rainwater in combination with gutters and downpipes (made from wood, bamboo, galvanized iron, or PVC) to provide a household with high-quality drinking water. A rooftop rainwater harvesting system might be a 500 cubic meter underground storage tank, serving a whole community, or it might be just a bucket, standing underneath a roof without a gutter. Rainwater harvesting systems have been used since antiquity, and examples abound in all the great civilizations throughout history
