A.   Permit Required For Use: No unauthorized persons 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 district inspector.
   B.   Indemnification Of County For Costs And Expenses: All costs and expenses incidental to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the county, or in any area under the jurisdiction of the county, from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
   C.   Separate Connections Required; Exception: A separate and independent building sewer shall be provided for every building; except, where one building stands at the rear of another on an exterior 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 county, outside the corporate boundaries of any incorporated municipality, does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned.
   D.   Standards: The size, slope, alignment, materials or construction of all sanitary sewers, including building sewers, 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 regulations of the public sewer system within the area where the sewer system is made available to the public. In the absence of suitable code provisions or in amplification thereon, the materials and procedures set forth in appropriate specifications of the American Society Of Testing and Materials (ASTM) and the water pollution control (WPCF) manual of practice no. 9 shall apply.
   E.   Elevation Of Building Sewer: 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.
   F.   Surface Drainage: No person shall make connection of roof downspouts, 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, unless such connection is approved by the district inspector for purposes of disposal of polluted surface drainage.
   G.   Excavations For Installation: 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 county outside the corporate boundaries of any incorporated municipality.
