2025-08-21 00:00:00 Sewer cleaning is a daily job in the process of maintaining a sewer in a utility company. For this reason, it was necessary to develop a mobile application that will record the field cleaning work performed, along with a record of possible problems in the functioning of the sewer system. This mobile application is a part of larger enterprise software system and as such cannot be used as a standalone application.
