KuttanadThis thesis by Christina Tang for the Center of Environmental Studies, Brown University deals with a study of water quality and attempts to ascertain the net benefits or costs from rainwater harvesting under a variety of scenarios for households in various water supply conditions.

Eighty percent of the 7,00,000 citizens of Kuttanad, a region in the coastal State of Kerala have no access to clean water. In Kuttanad, intensive untreated human sewage and agricultural activities have caused severe surface water contaminations. At the same time, other sources of freshwater are unreliable for drinking: groundwater is acidic due to the soil conditions and iron leaching; freshwater from public tap is infrequent; and water supply from private vendors is extremely expensive.
