Clean Drinking Water from the Tap in Tokyo
Narrator: Safe drinking water is the ultimate concern of everyone. While Tokyo’s tap water meets international standards for safe drinking water, that doesn’t reassure everyone.
Interviewee: I buy mineral water.
Interviewer: What brand?
Interviewee: My favorite brand is Volvic.
Interviewee: I don’t drink water out of tap at all, and I don’t use it for my cooking also.
Narrator: Eleven water treatment plans provide clean drinking water for the citizens and industries of Tokyo. At the number four, Misato purification plant, two different lines are in place to clean the water. Sludge fills, filtration and aeration are the same in both lines. Sodium hypochlorite is added to kill bacteria. An advanced line adds active charcoal filtration and ozone treatment to produce a very high quality drinking water. Unfortunately, the high cost of the advanced line means that the output of the two lines is blended before the water is delivered to Tokyo citizens.
