All discharges to a sewer shall be through an approved sewer
connection or at another discharge point expressly approved by the
Director in accordance with this chapter and with any rules, regulations,
or procedures established by the City as determined necessary by the
City to administer and implement this chapter. No person shall discharge
any waste or other substances into a manhole, catch basin or inlet.
No unauthorized person shall uncover, make any connections with
or opening into, use, alter, or disturb any part or appurtenance of
the POTW, nor discharge into the POTW, without first obtaining a written
sewer service lateral connection permit from the City.
Existing sewer service laterals may be used in connection with
new buildings only if they are found, on examination and test by the
Director to meet all requirements of this chapter and other applicable
laws and regulations. If an inspection by the City reveals that a
connection may create a health or environmental hazard, nuisance,
or is otherwise inconsistent with the purposes and requirements of
this chapter, the sewer service lateral shall be reconstructed or
repaired at the owner's expense.
Whenever possible, the sewer service lateral shall be brought
to the buildings at an elevation below the basement floor. No sewer
service lateral shall be laid parallel to, or within three feet of,
any bearing wall that might thereby be weakened. The depth shall be
sufficient to afford protection from frost. The sewer service lateral
shall be laid at uniform grade. The line shall be straight or laid
with properly curved pipe and fittings. Changes in direction shall
be made with no less than a forty-five-degree bend. Each bend of 45°
or more shall have an accessible cleanout. All excavations required
for the installation of a sewer service lateral shall be open trench
work unless otherwise approved by the City. Pipe laying and backfill
shall be performed in accordance with current ASTM specifications,
except that no backfill shall be placed until the City has inspected
the work.
Floor drains connected to the sewer service lateral shall be
required for all basements or cellars if the elevation of the public
sanitary sewer will service the building. All required floor drains
shall have check valves or backflow preventers that meet current laws
and regulations as determined by the City.
In all buildings in which any sewer service lateral is too low
to permit gravity flow to the public sewer, sanitary sewage carried
by such drains shall be lifted by artificial means and discharged
to the sewer service lateral, at the owner's expense, and subject
to approval by the City.
All excavations for sewer service lateral 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 City at the expense of the owner.
No person shall connect (or allow to remain connected) roof
downspouts, exterior foundation drains, areaway drains, or other sources
of surface runoff or groundwater to a sewer service lateral or building
drain that in turn is connected directly or indirectly to a public
sanitary sewer. Any such connection shall be permanently disconnected
at the sole expense of the owner of the premises.
Pretreatment of any discharge to the public sewer, including,
but not limited to, grease, oil, and sand interceptors, shall be provided
when, in the opinion of the Director, they are necessary.
