Activity for preserving the pure water of Mukawa River

To protect the Mukawa River, which boasts some of the clearest water in Hokkaido, the company has set up a sand control dam* in the balancing reservoir so that they can manage the reservoir water and maintain the quality of the water that ultimately runs into the Mukawa River.

Moreover, after consultation with Mukawa Town, Water oaks were planted within the site to conserve the rich water sources that can be found in the thick forest. The oaks, which are locally grown in the neighboring communities, are known for effective wellhead protection.

* Sad control dam:
It is set up in a minor stream and makes it possible to prevent landslide damage.
It is different from general dams and is specifically designed to prevent landslide damages.
