It is unlawful for any person to make or cause to be made any individual connection to a city sewer unless such connection is made by means of a tee- or wye-branch, using city-approved methods and materials. Every main building shall be separately connected to the public sewer unless otherwise approved by the director. Each unit within a main building that is of separate ownership shall be separately connected to the public sewer unless otherwise approved by the director. A private garage, out-building or accessory dwelling unit located on the same property may have its plumbing connected to or with the plumbing of the main building if approved by the director. (Ord. M-4431 § 2, 2023; Ord. M-4359 § 2, 2021; Ord. M-4022 § 33, 2012; Ord. C-432 § 5, 1951)
