A. 
No unauthorized person shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance without first obtaining a written permit from the Plumbing Inspector. The owner or his agent shall make application on a special form furnished by the City. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Plumbing Inspector and Wastewater Superintendent. The permit and inspection fees are as established by resolution of the City Council.
B. 
There shall be two classes of building sewer permits:
(1) 
Residential and commercial services.
(2) 
Service to establishments producing industrial wastes.
C. 
All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the City from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
D. 
A separate and independent building sewer shall be provided for every building.
E. 
Existing building sewers may be used in connection with new buildings only when they are found on examination by the Plumbing Inspector to meet all requirements of this chapter.
F. 
The size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, joining, testing and backfilling the trench shall all conform to the requirements of the plumbing code or other applicable rules and regulations of the City, state or other relevant regulatory agency.
G. 
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, domestic wastewater carried by the building drain shall be lifted by an approved means and discharged to the building sewer.
H. 
Roof leaders, surface drains, groundwater drains, foundation footing drains and other clear water drains shall be connected wherever possible with a storm sewer, but they shall not be connected to a building sewer which discharges into a sanitary sewer or private wastewater treatment plant. If stormwater or clear water is being discharged into a sanitary sewer, the Plumbing Inspector will give the offending person seven days' notice to disconnect. Failure to disconnect after notice authorizes the Plumbing Inspector or Control Authority to cause disconnection and assessment of the costs of the disconnection against the property involved. The Plumbing Inspector or Control Authority may, in the alternative, institute legal action for violation of this subsection.
I. 
The connection of the building sewer into the public sewer shall conform to the requirements of the City Plumbing Code and other applicable laws, rules and regulations.
J. 
The applicant for the building sewer permit shall notify the Plumbing Inspector when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Plumbing Inspector or his representative.
K. 
All excavations for the building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkway and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the City.
L. 
Whenever permits for new connections to the sewerage system are applied for under this section, the Control Authority may determine whether adequate collection and treatment capacities exist in the system to properly accommodate the proposed new connections. If the determination is that either existing collection or treatment capacity in the system is inadequate for properly handling the proposed new connections, the connections shall be disallowed.
