All public sewers which shall be ordered by the Mayor and City
Council in any street or highway shall, whenever practical, be laid
out as nearly as is practicable in the center of such street or highway,
and shall be constructed of such materials and of such dimensions
as the Mayor and City Council direct.
No connection shall be made between any private sewer or building
sewer and any public sewer, or between a private drain and any public
drain unless it is of such size, material, construction, depth and
location as the Director of Public Works may direct, and until the
appropriate permit has been obtained from the Director of Public Works
and all fees, charges, and assessments have been paid.
