No unauthorized person shall uncover, make any connections with or opening
into, use, alter or disturb any public sanitary sewer system or appurtenance
thereof without first obtaining a written permit from the Superintendent.
All costs and expenses incident to the installation and connection of
the building sewer shall be borne by the property owner. The owner shall indemnify
the district from any loss or damage that may directly or indirectly be incurred
by the installation of the building sewer.
A separate and independent building sewer shall be provided for every
building; except, where one building stands at the rear of another or on an
interior lot and no private sanitary sewer system is available or can be constructed
to the rear building through an adjoining alley, court, yard or driveway,
the building sewer from the building next to the sewer may be extended to
the building away from the sewer 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 Superintendent, to meet
all requirements of this chapter.
In all buildings in which any building drain is too low to permit gravity
flow to the public sanitary sewer system, sewage carried by such building
drain shall be lifted by an approved means and discharged to the building
sewer.
No person shall make connection of roof downspouts, exterior foundation
drains, areaway drains or other sources of surface runoff, groundwater or
sump pump discharges to a building sewer or building drain which in turn is
connected directly or indirectly to a public sanitary sewer.
The applicant for the building sewer permit shall notify the Superintendent
when the building sewer is ready for inspection and connection to the public
sanitary sewer system. The connection shall be made under the supervision
of the Superintendent or his representative.
All excavations for building a sewer installation shall be adequately
shored and guarded with barricades and lights so as to protect workers and
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 district.
