The city sewer system mentioned in this chapter, and to which this chapter relates, embraces and includes not only the entire sewer system owned and operated by the city, but also any and all other sewer lines and systems located in or about the city owned or operated by any other person. The sewers of the city sewer system are called main sewers and lateral sewers. The sewer lines laid by property owners on their land, to connect buildings, structures and fixtures with the city sewer system, are called house sewers.
