The story of well water

Be careful of domestic wastewater that comes out every day!
Domestic wastewater, such as kitchen and bath water, becomes sewage, purified at a sewage treatment plant, and then returned to nature.
Try to live a nature-friendly life so that the amount of domestic wastewater can be reduced as much as possible, such as treating the oil that is no longer needed without flushing it as it is, or reusing the bath water for washing.

Well water that uses water that has soaked underground can be contaminated with various substances.
Contamination of well water due to chemical substances is not noticed in daily management and inspection.
Use tap water that has been confirmed to be safe for drinking water, and use well water as miscellaneous water such as washing water.
If you have any questions about using well water, please contact Health and Welfare Center Health Sanitation Division.
