○Tap Water

    In Prout Village, there is no sewage flowing into the rivers, improving the water quality. The water drawn from the river's intake tower is managed for its quality at the control room (ICT, electricity, water) of the administration building, and then sent to households. Sewerage and sewage treatment plants are unnecessary, and wastewater is returned to farmland. Furthermore, the water pipes used do not contain substances like lead and do not rust.

    To draw clean water, the local water source environment is strictly managed, and water is drawn as close as possible to the point where it springs. As a result, people can drink water that is rich in minerals.

    For municipalities without a nearby river, the first priority is to supply water through a pipe from the nearest municipality. If this is not possible, the municipality will relocate to a place where water can be supplied.

    In cases where water sources cannot be secured, such as on islands, water is supplied by connecting to a water source in another area via a submarine water pipe. However, for islands where a submarine water pipe cannot be built, an underground dam is considered. An underground dam is a facility that blocks the flow of groundwater by creating a wall in the ground that does not allow water to pass through, and it is already used in various countries including Japan.
