(A) The grade of a minimum six-inch building sewer shall not be less than one-quarter inch per foot. Minimum slopes for larger diameter pipes shall conform to the Recommended Standards for Wastewater Facilities as promulgated by the Great Lakes-Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers, 1997 Edition, and as thereafter amended, a copy of which shall be maintained on file in the Department of Engineering, Traffic, and Inspection Services.
(B) All pipe shall be laid on a uniform grade and, where possible, on a straight line. Where any sewer cannot be laid on a straight line, a manufactured fitting shall be used to make deflections that exceed three-quarter inches per foot.
(C) Public sewers to be dedicated to the city shall be located in a dedicated easement or the public right-of-way in front of the proposed development. The installation of sewers in easements along rear property lines is discouraged and prohibited without written request and authorization from the City Engineer. The installation of public sewers along rear lot lines may be considered when it is deemed by the city to be physically prohibited to standard sewer installation methods, or necessary to service an adjacent unsewered area.
