Water is a vital resource for all living beings, yet it is increasingly threatened by pollution and the wastage of rainwater. Water bodies such as rivers, lakes, and ponds are being contaminated by industrial waste, household garbage, sewage, and plastic, making the water unsafe for drinking, agriculture, and aquatic life. This pollution not only harms ecosystems but also reduces the availability of clean water for human use., At the same time, a large amount of rainwater is wasted every year. Due to rapid urbanization, natural surfaces are covered with concrete, preventing rainwater from seeping into the ground. Instead of being stored or used, it flows into drains and is lost. This leads to declining groundwater levels and water scarcity, especially during dry seasons., The combined effect of water pollution and poor rainwater management creates a serious water crisis. There is an urgent need to control pollution and adopt effective rainwater harvesting methods to ensure sustainable water availability for present and future generations.
