Q3-4 What should I do at the end of the drainage facility?

In principle, it is necessary to discharge directly to existing public sewers or rivers outside the application area, but if it is difficult, you may go through a private drainage system. In this case, be sure to obtain the consent of the owner of the neighboring land before applying for permission. (Please note that it is not a condition of permission, and the city cannot take responsibility.) 。
