Sewers shall be designed in accordance with the Domestic Wastewater
Facilities Manual of the PA Department of Environmental Protection
and the construction details and drawings which are a part of these
Rules and Regulations.
Construction of sewers will not be permitted until the proper
state permits have been obtained.
[Revised 11/11/2020]
Prior to final acceptance of the sewers by the Butler Area Sewer
Authority, the developer shall submit one set of complete and final
as-constructed ("as-built") drawings of the sanitary sewer system
extension to the Authority for review and approval. The information
required shall include, but not be limited to, the turning angle and
distance between manholes, the top elevation of each manhole, the
invert elevation of each pipe entering and leaving each manhole, the
exact location of all house sewer connections relative to the nearest
manhole downstream, the length of each six-inch lateral, and the location
and invert elevation of each inspection tee at the end of each lateral.
After the Authority has approved (in writing) the “as-built”
drawings, the developer shall submit complete and final “as-built”
drawings sealed by a Professional Engineer. The “as-builts”
shall be in the form of both 1) reproducible Mylar drawings, and 2)
digital GPS coordinates of the manhole centers referenced to the PA
State Plane Coordinate System.
Easements shall be recorded in the name of the Butler Area Sewer
Authority for all sewers to be constructed outside dedicated street
rights-of-way.
The designated Inspector of the Butler Area Sewer Authority
shall be given at least 24 hours' notice before construction begins.
Special Notice Regarding Testing.
(A)
The developer is hereby informed that construction of sewers
beyond an initial 1,000 feet of pipe will not be permitted until satisfactory
test results are obtained.
(B)
Should the developer desire to test before completion of service
connections, he may do so, but will be required to retest the same
line with the completed service connections before final acceptance
by the Authority. Subject to unsatisfactory initial test results and
at the Authority's option, testing at 1,000-foot maximum increments
will be required throughout the project.
(C)
Each section of sewer between manholes, or for longer distances
if the Authority's representative shall so direct, shall be cleaned,
tested and inspected. All repairs shown to be necessary by the tests
are to be made promptly. Broken or cracked pipe shall be replaced
and all deposits removed and the sewer left true to line and grade
and entirely clean. Each length of sewer is to show a full circle
of light from manhole to manhole.
(D)
All sewers shall be tested for leakage, and any section of sewer
showing leakage in excess of the amount hereinafter set forth shall
be rejected.
(E)
The air test shall be conducted by the developer under the supervision
of the Authority's representative and shall be performed with Air-Loc® equipment manufactured
by Cherne Industrial, Inc., Hopkins, Minnesota, or approved equal.
(F)
The developer may desire to perform an air test for his own
purposes prior to backfilling; however, the acceptable air test shall
be performed after backfilling has been completed.
(G)
Each section of sewer being tested shall be temporarily sealed
off by means of suitable plugs. In addition, all wyes, tees, or ends
of lateral stubs shall be sealed with suitable removable caps securely
fastened to withstand internal test pressures.
(H)
The procedure and criteria to be used for air testing shall
conform to that described by the manufacturer of the respective pipe
used and shall be in general conformance with ASTM F-1417.
[Revised 11/11/2020]
(I)
All gauge pressures in the test shall be increased by the amount
of groundwater pressure at the crown of the pipe.
(J)
It is essential that the plugs be properly secured and care
be exercised in their removal. All plugs shall be blocked and carefully
braced to prevent sudden release of compressed air, slippage, or blowout
due to internal pressure.
(K)
To protect against injury due to the above-mentioned hazards,
no one shall be permitted in the manhole or at the end of the pipe
test section during testing.
(L)
The pressurizing equipment shall have a safety gauge which shall
limit the loading on the sewer line to 10 psi. In addition, the calibrations
on all pressure gauges shall be no greater than 0.10 psi.
(M)
If the pipe installation fails to meet these requirements, the
developer shall determine the source or sources of leakage, and he
shall repair or replace all defective materials and workmanship, including
rebackfilling, compaction, and all surface restoration.
(N)
Immediately following the testing, an amount of not less than
500 gallons of fresh water shall be flushed through the system from
the upstream end of each separate branch. After the fresh water has
flowed through, the newly constructed pipe shall be internally inspected
by the developer using closed-circuit television equipment. A color
CCTV video on suitable media shall be supplied to the Authority and
shall be complete with audio description, on-screen titling showing
manhole numbers, direction of flow, size and type of pipe, date of
the inspection, and on-screen footage display accurate to tenths of
one foot. In the event any defects are found, they shall be properly
repaired by the developer, regardless of the outcome of the air pressure
testing done previously. The CCTV video shall become the property
of the Authority.
