Quantifying household water use and its determinants in low-income water scarce households.
Water discourse in Karachi revolves around a theme of scarcity. KWSB projects a demand of over 1200 million gallons a day (MGD) for Karachi. With current water supply around 550 MGD, most of Karachi’s water problems are reduced to that of a “shortage” of water. However, the KWSB projections of water demand are not based on actual usage locally; instead, the projections are based on a uniform and exaggerated assumed per capita demand that is not representative of household usage in Karachi. In this study, we conduct household surveys in the low income township of Lyari to understand how and how much water households use for their daily activities. A better understanding of actual water demands in the city can help lead to better targeted water infrastructure investments and policies.
