Descriptions:
On the morning of October 30, the water in the Hirose River, which flows through the city of Sendai, turned out to be red and cloudy. The Hirose River has flowed with red or brown muddy water many times in the past, and Miyagi Prefecture and other authorities are investigating whether rust in rainwater pipes may be to blame. A man catching crabs in the Hiros River said, “This is disgusting, isn’t it disgusting?” “I didn’t expect it to be like this. What could it be? The Hirose River is dirty red in color. -brown. The contrast is noticeable when compared to white-bodied wild birds. Around 7 a.m. on the 30th, police received a series of reports that the Hirose River was polluted near Mukoyama in the Taihaku area. No damage, such as fish kills, has been confirmed at this time. If you look at it from the sky, you can see that the color of the river changes along the 1.5 km from Tayyabashi to Miyazawabashi. A similar thing has actually happened in the past. Reporter’s report (December 2010) “Red water flows from storm drain outlet.” Fourteen years ago, muddy water flowed from a storm drain leading to the river, turning the area red. The cause is believed to be rust in the drainpipes. This place is about 400 meters upstream from the Atago Ohashi Bridge. When I went there on the 30th… Press Release (30th): “You can see that the sewer there is a color similar to iron rust.” However, if you look at it from above, you will see that the red water extends further upstream than the storm drain. .I see that there is. So, when I walked about 300 meters upstream, I saw workers conducting an investigation at the request of the city of Sendai. Water flows from the open end of the rain pipe, giving the surrounding soil a reddish hue. Nearby, work was underway to strengthen the bridge. Although it is unknown whether the incident is related to construction work, the prefecture and other authorities are investigating the cause, saying that rust in the storm drain may have been washed away due to rain on the morning of the 30th.
