(A)   Building sewers and connection.  No person shall uncover, make any connections with openings into, alter, or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the control authority. One copy of the permit shall at all times be available for inspection at the site of the work.
   (B)   (1)   Sewer development charges and sewer connection fees.
         (a)   Sewer development charges.
            1.   There are established, in accordance with the provisions hereof, sewer development charges to defray part of the construction costs of sewer outfalls and treatment, which charges shall be payable as set forth herein by the developer or owner of the subdivision or developer or owner of industrial, commercial or residential sites.  Such sewer development charges shall be payable upon the execution of the relevant development agreement with the Town.
            2.   Sewer development charges shall apply to all subdivisions, land development, new buildings, and any redevelopment of land or buildings served by the Town’s sanitary sewer system, whether the facility served requires modification of or enlargement of the existing sewers or construction of new facilities and whether or not the facility is within or without the corporate limits of the Town.
            3.   From time to time the Board of Mayor and Aldermen of the Town shall establish by resolution for a designated fiscal year of the Town, the sewer development charge to be paid in accordance herewith.
         (b)   Sewer connection fees.
            1.   No permit to connect to the public sanitary sewer system shall be granted unless the applicant shall first pay to the Public Services Department of the Town a sanitary sewer connection fee, as established from time to time by the Board of Mayor and Aldermen by resolution for a designated fiscal year of the Town, based upon the following classifications:
               a.   For each residential single-family subdivision lot if a sewer main is already in place, such fees as established as aforesaid by the Board of Mayor and Aldermen plus the actual cost incurred by the Town to install a sewer tap;
               b.   For each residential single-family subdivision lot if a sewer main is being laid (such as new development), such fees as established as aforesaid by the Board of Mayor and Aldermen;
               c.   For each industrial, commercial and multi-dwelling (residential or commercial), such fees as established as aforesaid by the Board of Mayor and Aldermen; provided, however, that there shall be excluded from the calculation of such fee, if based on acreage of land, that acreage of land which lies in an area designated, at the time the fee is due, as flood way by the federal government.
      (2)   (a)   If there is no sewer available at a property line of an owner who wishes to develop such property, the owner shall be responsible for extending a sewer to such property upon terms as shall be acceptable to the Town.  Such terms shall be set forth in a development agreement between the Town and such owner.
         (b)   Sewer development charges as provided for herein shall not apply to existing municipalities or utility districts wishing to tie into the Town sewer system, but the sewer development charges shall be negotiated in such instances taking into consideration sewer fees and sewer use fees to be paid to the Town and amounts necessary to defray part of the Town’s sewer construction costs.  Agreements generated under this article and section shall be for a specific period of time and shall be reviewed annually.
         (c)   Whenever the Town enters into an agreement with a developer or owner relative to the extension of a sewer to his or her proposed development, a reasonable time limit shall be indicated in the agreement for the completion of said project.
   (C)   All costs and expenses incidental to the installation and connection of the building sewer shall be borne by the owner(s). The owners shall indemnify the Town from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer. All construction on the owner’s property shall conform to the Town of Collierville Plumbing Code.
   (D)   A separate and independent building sewer shall be provided for every building, except 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, but the Town does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned.
   (E)   Existing building sewers may be used in connection with new buildings only when they are found, on examination and testing by the control authority, to meet all requirements of this code.
   (F)   The size, slope, alignment materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench shall all conform to the requirements of the Building and Plumbing Code and other applicable rules and regulations of the Town.
   (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 gradient is too shallow to emit gravity flow to the public sewer, sanitary sewage carried by such building gradient shall be lifted by an approved pumping system and discharged to the building sewer. The installation and operational expenses of this system shall be borne solely by the property owner.
   (H)   No person(s) shall make connection of roof downspouts, foundation drains, area-way drains or other sources of surface runoff or groundwater to a building sewer which in turn is connected directly or indirectly to a public sanitary sewer unless connection is approved by the control authority for purposes of disposal of polluted surface drainage.
   (I)   The connection of the building sewer into the public sewer shall conform to the requirements of the Building and Plumbing Code and other applicable rules and regulations of the Town. All such connections shall be made gastight and watertight and verified by proper testing. Any deviation from the prescribed procedures and materials must be approved by the control authority before installation. The control authority shall have the right to inspect the work at any stage of construction, and in the event the covers of all building sewer manholes, inspection chambers, cleanouts and the like shall be watertight and shall be capable of withstanding without damage or displacement any traffic load to which they may be subjected.
   (J)   The applicant for the building sewer permit shall notify the control authority before performing those portions of the work to be done underground, and when the building sewer is ready for final inspection and connection to the public sewer. The connection and testing shall be made under supervision of the control authority.
   (K)   All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Town. The posting of a bond of appropriate value may be required to safeguard the interest of the Town as regards damage to public property.
