If any person covers or backfills any side sewer or public sewer without having obtained approval, the city may require the person to uncover the work so that a proper inspection and approval can be made. The city shall have access at reasonable times to all single-family, multiple dwellings and other structures, for the purpose of examining any and all plumbing outlets and/or side sewers for the purpose of ascertaining whether the provisions of this chapter are being complied with.
