Rainwater Harvesting for Domestic Consumption in Bangladesh: Sizing and Construction of Storage Cisterns 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.
Key words: Bangladesh, Cistern sizing, Rainwater Harvesting
The Problem and its Setting
Rainwater harvesting is the principle of collecting and using precipitation from a catchment area. The term is derived from a more general connotation of water harvesting that denotes the collection, storage, and use of water mainly for the purpose of irrigation. Nowadays the term generally comprises the collection of run-off on micro-catchment principles, such as roofs.
The purpose of this study is to assess a sustainable rainwater harvesting solution for multistoried residential apartments in Dhaka, Bangladesh through an extensive review of the literature and collection and analysis of secondary data. The objectives of the study were as follows:
≠ Identify and analyze the rainwater harvesting methods of Bangladesh, ≠ Analyze the significance of rainwater harvesting in the urban residential areas of Bangladesh, ≠ Develop a solution for rainwater harvesting solution for a typical multistoried residential apartment in Dhaka, Bangladesh, and ≠ Utilize programming and visualization to assess the efficacy of the solution.
