After confirmation, we will contact you with the scheduled date to visit the consultation desk. If we determine that a response can be provided without a face-to-face meeting, we will reply via email or phone. In such cases, please note that the face-to-face appointment will be canceled.

 We will start accepting application forms, commencement notifications, and completion notifications related to public sewerage facility construction work (self-funded construction) via electronic application from July. Accordingly, we plan to end acceptance of applications at the counter from September onward, and we appreciate your understanding.

 When submitting, please be sure to check that there are no omissions in filling out the form, no missing seals, and no missing documents.

 The period from application to the issuance of the approval document usually takes about one week, but depending on the content, it may take more than one month. Please allow sufficient time for the procedure.
