The provision of piped potable water across India has played a significant role in preventing diarrhoea-related deaths. Here are some key points regarding the impact of piped potable water provision in India, as outlined by a WHO study:

• Improved water quality: Piped potable water systems ensure access to clean and safe drinking water, which reduces exposure to waterborne pathogens and chemicals that can cause diarrhoea.
• Reduced contamination: Piped water is less likely to be contaminated by fecal matter or other sources of pollution, reducing the risk of diarrhoeal diseases.
• Prevention of waterborne diseases: UNICEF estimates that 88% of diarrhoeal deaths are due to inadequate sanitation and contaminated water. Access to piped water helps to combat these waterborne diseases.
• Improved hygiene practices: With access to reliable and clean water, individuals can practice proper handwashing, which is crucial in preventing the transmission of diarrhoeal diseases.
• Community health benefits: Piped water provision benefits the entire community, as it reduces the burden of waterborne diseases, decreases healthcare costs, and improves overall public health.

Overall, the provision of piped potable water in India has had a positive impact on reducing diarrhoea-related deaths by ensuring access to clean drinking water and promoting better hygiene practices.
