Abstract	Rainwater harvesting (RWH) is a sustainable water management practice that involves the collection, storage, and utilization of rainwater for various purposes. This method has gained significant attention due to increasing water scarcity, urbanization, and climate change impacts. The process typically involves capturing rainwater from rooftops, surfaces, or catchment areas, directing it into storage systems such as tanks or underground reservoirs, and subsequently using it for irrigation, domestic consumption, or groundwater recharge. The benefits of rainwater harvesting are multifaceted. It reduces dependency on conventional water sources, mitigates flooding and erosion, and enhances groundwater levels. Additionally, RWH systems can be designed to filter and purify collected water, making it suitable for potable use. The implementation of rainwater harvesting can lead to significant cost savings in water bills and contribute to environmental sustainability by promoting water conservation practices. Rainwater harvesting (RWH) is the most traditional and sustainable method, which could be easily used for potable and nonportable purposes both in residential and commercial buildings. This could reduce the pressure on processed supply water which enhances the green living. This paper ensures the sustainability of this system through assessing several water-quality parameters of collected rainwater with respect to allowable limits. A number of parameters were included in the analysis: pH, faecal coliform, total coliform, total dissolved solids, turbidity, NH3–N, lead, BOD5, and so forth. Despite its advantages, the adoption of rainwater harvesting faces challenges, including initial setup costs, maintenance requirements, and regulatory barriers. Public awareness and education are crucial for overcoming these obstacles and promoting widespread implementation. Overall, rainwater harvesting presents a viable solution to address water scarcity and promote sustainable water resource management in both urban and rural settings.
