Integrating mosquito control and drinking water quality standards (DWQS) in urban rainwater harvesting systems

Abstract

This study investigates the integration of advanced rainwater harvesting systems in urban residential buildings, focusing on their effectiveness in meeting Drinking Water Quality Standards (DWQS) and implementing effective mosquito control measures. As global challenges such as water scarcity and climate change intensify, sustainable water management practices have become critical. Rainwater harvesting, a time-tested approach, is increasingly recognized for its potential to reduce reliance on municipal water supplies and enhance the resilience of urban environments. The research addresses significant gaps in the current literature by evaluating a comprehensive system that not only harvests and filters rainwater for potable use but also manages grey water for non-potable applications. Through simulation and laboratory testing, the study assesses the system’s ability to meet DWQS while preventing mosquito breeding, which is vital for public health, particularly in regions prone to vector-borne diseases. The results indicate that the system is highly effective in maintaining water quality and controlling mosquito populations. The water collected consistently met DWQS, and no mosquito larvae were detected in the final storage tanks. These findings highlight the system’s suitability for integration into urban residential designs, supporting both sustainability and public health objectives.
