Consultation on drinking water
Last Updated November 9, 2018
The story of tank water
Drinking water from buildings and condominiums is once stored in a water tank called a "water receiving tank" and then supplied to your home faucet. Management of water through the receiving tank must be performed at the responsibility of the building owner and the person who lives. Neglecting this management can cause drinking water to become dirty and lead to unexpected accidents. In order to drink safe water, be sure to manage the aquarium.
1 Principles of Management
Let's try for proper management so that you can drink water with peace of mind at any time.
- Clean the aquarium once a year
The receiving tank and elevated water tank must be cleaned regularly once a year. Always keep it clean. - Regular inspections and maintenance
Check regularly for holes and cracks in the aquarium. Let's clean the area around the aquarium. - Check the water every day
If there is any abnormality in water color, turbidity, smell, taste, etc., contact Environmental Sanitation Section immediately.
2. When drinking water is contaminated
In the unlikely event that drinking water is contaminated, take the following measures immediately.
- Stop the water supply and notify the user immediately and contact Environmental Sanitation Section.
- Please follow the guidance of Environmental Sanitation Section to remove the cause of water contamination, clean the water tank, and resume water supply.
- While water supply is stopped, use a faucet directly connected to the water supply to secure drinking water.
3. When a disaster occurs
If there is a situation that may affect water quality, such as an earthquake or heavy rain, check the water tank. If there is any abnormality, repair it as soon as possible.
(Note) About well water
Well water can be contaminated with a variety of substances. It is recommended that you use it for purposes other than drinking.
