Establishing piped potable water supply across India can have a significant positive impact on reducing waterborne diseases and preventing diarrhoea deaths. According to a recent study conducted by WHO, here are some key ways in which this can happen:

• Improved water quality: Piped potable water supply systems can ensure that water is treated and purified before it reaches households, which can significantly improve its quality and reduce the risk of waterborne diseases.
• Increased access to safe water: Pipelines can connect remote and rural areas, ensuring that people have access to safe and clean drinking water, which can reduce reliance on unsafe sources of water and thus, reduce diarrhoea cases.
• Promotes hygiene and sanitation: With access to piped water supply, people are more likely to practice good sanitation methods, such as washing hands with soap. This can further reduce diarrhoea cases.
• Reduced burden on healthcare: Diarrhoea is a leading cause of hospitalization and death in India. By reducing the number of diarrhoea cases, there will be less pressure on healthcare systems, which can result in better healthcare outcomes overall.

Overall, establishing piped potable water supply across India can be an effective means of reducing the incidence of waterborne diseases, especially diarrhoea, and preventing associated deaths.
