Providing piped potable water across India would have a significant impact on public health, as identified by a WHO study. - Reduced incidence of waterborne diseases: Access to safe and clean drinking water can significantly reduce the incidence of waterborne diseases such as cholera, typhoid, and dysentery. This is especially crucial in a country like India, where these diseases are prevalent, especially in rural areas. - Improved maternal and child health: The lack of access to safe drinking water has a direct impact on maternal and child health. Piped water supply can ensure that pregnant women have access to safe and clean drinking water, which would improve maternal and child health outcomes. - Reduced malnutrition: In India, malnutrition is a significant public health issue. The availability of safe and clean drinking water can ensure better nutritional outcomes, especially for children. - Improved overall health outcomes: Access to clean water can also have a positive impact on overall health outcomes, including reducing the burden of non-communicable diseases such as diabetes and hypertension. In conclusion, providing piped potable water across India would have a significant impact on public health, improving outcomes for individuals and communities.
