Drinking water sources refer to the various natural and man-made locations where water suitable for human consumption can be obtained. Common sources include rivers, lakes, and groundwater from aquifers. These sources are often treated to remove impurities and ensure safety before being distributed to homes and communities. In urban areas, drinking water may also come from reservoirs and municipal water systems. Rainwater harvesting is another method, where rain is collected and stored for later use. Proper management of these sources is essential to maintain water quality and availability for the population.
