Rainwater harvesting for domestic consumption in Bangladesh: Sizing and construction of storage cisterns
Conference Paper

Overview
abstract
Bangladesh has an emerging problem with water supplies not adequate to meet even the minimum requirements for potable water. Surface water is being continuously contaminated by both industrial and human pollutions; rapidly increasing demands due to population explosion results in withdrawal of ground water at a faster rate than it is replenished by recharge. This problem can easily be mitigated through rainwater harvesting, taking advantage of high quantities of rainfall in the country. This study proposes to provide some guidelines for economic rainwater harvesting for domestic consumption in urban areas of Bangladesh. The guidelines have been formulated using existing data on rainwater harvesting systems. Based on these guidelines, a mathematical model has been developed to figure out cistern sizes for collection of rainwater. The products of this research are a) computer program for calculating domestic water requirements and sizing storage cisterns and b) an animation of the proposed rainwater harvesting system. These can be used as teaching tools to demonstrate the construction methods of such a system and the benefits of the technique. American Society for Engineering Education, 2010.
