All required tap connection and inspection fees shall be paid
at the time of making application for permission to make a connection.
No work shall commence before the payment of any aforementioned
tap connection and inspection fee and issuance of the aforementioned
connection permit.
Unless written permission is obtained from the Board and from
the Allegheny County Health Department, a separate connection and
corresponding tap connection and inspection fees shall be required
for each equivalent domestic unit, as defined in the Sewer Rate Resolution
of the Authority, whether constructed as a separate building or detached
unit or as one of a pair or row, but a single connection with payment
of the tapping fees for the appropriate number of actual EDUs served
will be permitted to serve a school, factory, apartment house or other
permanent multiple-unit structure whose individual apartments or units
may not be subject to separate ownership.
Connections to the main sanitary sewers shall be completed within
60 calendar days after approval of the application and payment of
required fees.
All connections to the sanitary sewers shall be subject to certain restrictions as to unacceptable sanitary sewage which are set forth herein in Article
V.
At the time of inspection of the connection, the owner or owners
of properties shall permit the inspector full and complete access
to all sanitary and drainage arrangements and facilities in each building
and in and about all parts of the property. No building sewer line
shall be covered over, or in any manner concealed, until after it
is inspected and approved by said inspector.
It is the intention of these rules and regulations that the
entire connection be inspected at one time; however, if the property
owner feels that special conditions warrant more than one inspection,
he may request the same, subject to such additional inspection fees
as the Board shall determine.
All sewer pipe shall be installed in strict accord with the
manufacturer's recommendations. Where rock trench foundation exists,
a six-inch stone aggregate cradle shall be provided under the pipe
and in all cases a minimum four-inch stone aggregate cradle shall
be provided under the pipe and a minimum twelve-inch stone aggregate
backfill over the pipe.
All pipe shall be installed with a minimum slope of 1/8 inch
per foot and a minimum cover of 3 1/2 feet unless otherwise approved.
All pipe shall be laid to an even grade and straight alignment to
the public sanitary sewer. All pipe shall be laid with full and even
bearing, and no block supports will be allowed. Bell holes shall be
dug to allow sufficient space to properly make each joint. Backfill
shall be tamped uniformly around the pipe. All work shall be done
in a workmanlike manner and shall provide a durable installation.
A four-inch trap with a four-inch vent and cover and a four-inch
cleanout shall be installed a maximum of five feet from the building
or as approved by the Authority Engineer. The vent shall be so situated
as not to allow the discharge of any surface water to the sanitary
sewer.
Commercial installations must also comply with all local construction
regulations (refer to § 65-47).
Maintenance and repair of all building sewers shall be the responsibility
of the property owner.
Old building sewers may be used to connect existing buildings
to the sewer system only when the Authority's representative determines
that the old sewer is in an acceptable condition. The condition of
the existing building sewer will be determined in the following manner:
A minimum four-inch diameter vertical riser shall be constructed by
the property owner at his expense. The riser shall be located at the
point where the existing sewer connects to the public sewer system.
Flow in the existing line will be observed in the riser and a determination
of the condition of the existing line made. If flow observed is excessive,
indicating infiltration, the line will be rejected; otherwise, it
will be accepted. If rejected, the owner of the property shall install
a new building sewer to comply with these rules and regulations.
All residential dwellings may be connected to the sewer system
by means of an optional minimum four-inch connection pipe, provided
the construction is in strict compliance with the following construction
requirements and procedures as set forth in Exhibit I and Exhibit
I-A. All commercial or industrial connections shall require
a minimum six-inch lateral connection.
