(5) Installation.
(a)
Installation of pipe must be done by qualified persons.
(b)

contractors.
(c)
Before digging the trench, the installer should expose the lateral
connection and the building drain. Trench width shall be kept to a
minimum width and have uniform slope at an approved grade as near
as possible at right angles to the street. Excavate all trenches at
least six inches below the bottom of the pipe. Place an aggregate
backfill, maximum of three-fourths-inch gravel size, in the trench
to grade of the pipe. Install the pipe, keeping any gravel, dirt or
water from entering the pipe. Place six inches of aggregate on top
of the pipe, ensuring uniform bedding to all sides of the pipe. The
remainder of the trench may be backfilled with material from the original
excavation if satisfactory. The sewer line trench shall have a minimum
three feet horizontal separation and 18 inches vertical separation
from other pipelines such as water service lines, gas lines, french
drains or storm sewers.
(d)
Inspection. The Borough or the Borough's authorized representative
must be present to visually inspect the installation prior to backfilling
the sewer lateral trench. Absolutely no backfill or other cover shall
be placed on the sewer until it has been inspected by the Borough.
Should the sewer be backfilled without inspection, the line will be
required to be exposed at the cost of the applicant for inspection.
(6) Testing.
(a)
Building sewer water test. A plug shall be inserted at the test
tee at the junction with the service connection stub. The plug at
the test tee shall remain in place until the building sewer and building
drain pass all required tests. The building sewer shall be filled
with water so that all portions of it shall be tested with 10 feet
of headwater, with inspection ports and cleanouts being capped after
water level has reached the overflow rims, thereby expelling air as
the building sewer is filled. The 10 feet of water head may be accomplished
by a temporary extension to the fresh air vent on the building trap
or other approved temporary standpipe connection, or if connected
with the building drain, then interior drainage plumbing may be used
for this purpose. The water shall be kept in the system for at least
15 minutes with no loss in water level in the standpipe. If no loss
of water, the building sewer shall be deemed tight at all points.
If the sewer fails the test, the source of the leak shall be identified,
repaired and inspected by the Borough, and the sewer shall be scheduled
for retesting in the presence of the Borough until it passes.
(b)
Building sewer air test. A plug shall be inserted at the junction
with the service connection stub. The plug shall remain in place until
the building sewer and building drain pass the required tests. An
air test shall be made by forcing air into the sewer until there is
uniform gauge pressure of 5.0 pounds per square inch (psi). The air
source shall be disconnected and this pressure shall be held for a
test period of 15 minutes. Any adjustments to the test pressure required
because of changes in ambient temperature or seating of gaskets shall
be prior to the beginning of the test period.
(c)
Force mains. Force mains for grinder pumps and other sewage
pumps shall consist of plugging the end of the force main at the point
of connection with the public sewer and applying a pressure of 5.0
psi greater than the pump rating and maintaining such pressure for
15 minutes with no loss in pressure after disconnecting the source
of pressure.
(d)
Excessive reinspections required. The Borough reserves the right
to impose reinspection fees where it deems that the applicant or its
contractor is scheduling inspections prior to the work having been
properly completed or prepared of inspection.
(7) Final connection. If a completed connection to the building drain
is not made at the time of the installation of the building sewer,
a temporary plug shall be inserted into the end of the lateral and
shall not be removed until such time as the connection is made to
the building drain and a Borough representative is present to visually
inspect the final connection and backfilling of the trench.
The connection fees, customer facilities fees or tapping fees
imposed by this Borough shall be a lien on the improved property connected
to and served by the sewer system where such fees or charges are not
paid as provided herein, which lien shall be filed in the office of
the Prothonotary of Washington County, Pennsylvania, and shall be
collected in the manner provided by law for the filing and collection
of municipal claims. In addition, the payment of said fees imposed
hereunder may be enforced by the Borough in any manner appropriate
under existing laws at the time they become due and payable.
This article shall be effective immediately and shall apply
to the entire sewer system owned and operated by the Borough.
Any person who shall violate any provision of this article shall,
upon conviction thereof, be sentenced to pay a fine not exceeding
$1,000 and/or to undergo imprisonment for a term not to exceed 30
days. Each day that a violation continues beyond the date fixed for
compliance shall constitute a separate offense. The officers and directors
of a corporation or other similar entity and the partners of a partnership
shall be liable for the penalties and fines imposed upon such organizations.
If any portion of this article is declared by any court of competent
jurisdiction to be invalid, it is the intention of the Borough Council
of the Borough of Canonsburg that all other parts remain in effect.
It is the intention of the Borough Council of the Borough of
Canonsburg that all ordinances that are in conflict with this article
are hereby repealed. Further, any ordinance not specifically mentioned
in this article that is not in conflict with this article shall remain
in full force and effect.
This article shall be effected immediately.
