Providing piped potable water across India can help avert diarrhoea deaths in the following ways:

• Piped water supply can ensure access to safe drinking water for a larger number of people, thereby reducing the incidence of waterborne diseases, including diarrhoea.
• Piped water supply can reduce the reliance on unclean sources of water, such as ponds, rivers, and wells. These sources may be contaminated with disease-causing pathogens, leading to and exacerbating the diarrhoea epidemic.
• Access to piped potable water can improve hygiene practices, such as handwashing, and promote sanitation. This can help prevent the spread of diarrhoeal diseases and promote good health and wellbeing.
• Piped water supply can reduce the burden of collecting water, especially for women and children, freeing up their time and resources, which they can use to improve their quality of life or access other basic needs.

In sum, providing piped potable water can be a crucial intervention in reducing diarrhoeal deaths in India by promoting hygiene, sanitation, and public health.
