The WHO study on providing piped potable water across India revealed several findings regarding disease prevention. Here are the key points: 1. Improved access to piped potable water reduces the risk of waterborne diseases like diarrhea, cholera, and typhoid. Contaminated water sources often lead to the spread of these diseases, especially in areas where sanitation and hygiene practices are inadequate. 2. Piped water supply systems ensure a consistent flow of clean water, minimizing the need for reliance on unsafe alternative sources such as ponds, rivers, or open wells. This reduces the likelihood of exposure to waterborne pathogens. 3. The study highlighted that the provision of piped water was more effective in disease prevention compared to alternative water sources, such as hand pumps or community wells, which are more susceptible to contamination. 4. Availability of clean drinking water directly improves hygiene practices, such as handwashing, which plays a critical role in preventing the transmission of diseases. Overall, the WHO study emphasized that the provision of piped potable water infrastructure is crucial for disease prevention, enhancing public health outcomes, and improving the well-being of communities across India.
