No authorized person shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the Superintendent.
A. 
There shall be two classes of building sewer permits:
(1) 
For residential and commercial service.
(2) 
For service to establishments producing industrial wastes.
B. 
In either case, 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 Superintendent.
C. 
A permit and inspection fee as provided in Chapter 142, Fees, shall be paid to the City at the time application is filed.
D. 
The owner shall be responsible for street damage in addition to that necessary for actual connection at the owner's sewer to the City lateral.
A. 
All costs and expense incident to the installation and connection of the building sewer shall be borne by the owner.
B. 
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.
A separate and independent building sewer shall be provided for every building, except that where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer.
Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Plumbing Inspector, to meet all requirements of this chapter. Such inspection shall be made by the Plumbing Inspector.
A. 
The size and slope of the building sewer shall be subject to the approval of the Plumbing Inspector, but in no event shall the diameter be less than four inches. The slope of such four-inch pipe shall be at least 1/4 inch per foot unless special approval is obtained from the Plumbing Inspector.
B. 
The building sewer shall be tar-coated, extra-heavy, cast-iron soil pipe conforming to ASTM Specification A74 and American Standards Association (ASA) Specification A-40.1 or asbestos-cement house connection pipe conforming to ASTM Specification C-428, Type II, minimum Class 2400. Joints shall be tight and waterproof. Any part of the building sewer that is located within 10 feet of a water service pipe shall be constructed of cast-iron soil pipe with leaded joints. Cast-iron pipe with leaded joints may be required by the Plumbing Inspector where the building sewer is exposed to damage by tree roots. If installed in filled or unstable ground, the building sewer shall be of cast-iron soil pipe, except that nonmetallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the Plumbing Inspector. Building sewer pipe shall have a maximum length of five feet between joints.
C. 
Joints and connections.
(1) 
All joints and connections shall be made gastight and watertight. No cement joints will be permitted.
(2) 
Cast-iron pipe joints shall be firmly packed with oakum or hemp and filled with molten lead not less than one inch deep. Lead shall be run in one pouring and caulked tight. The entire joint shall conform to AWWA Specification C600, Section 9. No paint, varnish or other coatings shall be permitted on the jointing material until after the joint has been tested and approved. The transition joint between cast-iron pipe and other pipe material shall be made with special adapters and joint materials approved by the Plumbing Inspector.
(3) 
Premolded gasket joints for the hub and plain-end, cast-iron pipe may be used if approved by the Plumbing Inspector and shall be a neoprene compression-type gasket which provides a positive double seal in the assembled joint. The gasket shall be a premolded one-piece unit designed for joining the cast-iron hub and plain-end soil pipe and fittings. The assembled joint shall be sealed by compression of the gasket between the exterior surface of the spigot and the interior surface of the hub. The joint shall be assembled following the manufacturer's recommendations using acceptable lubricant and special pipe-coupling tools designed for that purpose. The plain spigot end shall be forced into the hub end of the pipe for the full depth of the hub itself. The lubricant shall be a bland, flax-base, nontoxic material and shall not chemically attack the gasket material.
(4) 
Asbestos-cement pipe joints shall follow the manufacturer's recommendations, using properly designed couplings and rubber gaskets pursuant to the published information relating thereto.
D. 
No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at a uniform grade and in straight alignment insofar as possible. The changes in direction shall be made only with curved pipe and fittings which have been approved by the Plumbing Inspector.
E. 
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, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer. Such means of lifting the sewage shall be installed and maintained at the owner's expense at no expense to the City.
F. 
No person shall make connection of roof downspouts, exterior foundation drains, areaway drains or other sources of surface runoff or groundwater to a building sewer or building drain which, in turn, is connected directly or indirectly to a public sanitary sewer or combined sanitary and storm sewer.
G. 
The connection of the building sewer into the public sewer shall conform to the requirements of the building and plumbing codes[1] or other applicable rules and regulations of the City or the procedures set forth in appropriate specifications of the American Society for Testing and Materials and Water Pollution Control Federation Manual of Practice No. 9. All such connections shall be made gastight and watertight. Any deviation from the prescribed procedures and materials must be approved by the Plumbing Inspector before installation.

Editor's Note: See Ch. 148, Building Construction, and Ch. 228, Plumbing Standards.
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.
A. 
All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard.
B. 
Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the City. All excavations for the installation of a building sewer shall be open trench work unless otherwise approved by the Plumbing Inspector. Pipelaying and backfill shall be performed in accordance with ASTM Specification (C 12), except that no backfill shall be placed until the work has been inspected by the Plumbing Inspector.
C. 
The plumber performing such work shall notify the Plumbing Inspector when the laying of a house sewer is completed.
D. 
The filling of a trench before inspection is made will subject the plumber to whom a permit is issued to a penalty as provided in § 1-1 of this Code for each offense, and he may be required to reopen the trench for inspection.
When a building is taken down and there is no other building using the sewer lead, it shall be sealed at the old wall with concrete so that no dirt from the cellar will wash into the sewer.
In case of a violation of any of the rules and regulations of the City by a plumber, his journeyman plumbers or other persons in his employ, the plumber's license may be suspended or his license may be revoked by the City.
