[HISTORY: Adopted by the Borough Council of the Borough of
Franklin Park as indicated in article histories. Amendments noted
where applicable.]
[Adopted 11-10-1993 by Ord. No. 404-93]
All roofs, paved areas, yards, courts, courtyards or areas using
a topping or finish capable of collecting water shall be drained into
a separate storm sewer system or a combined sewer system where such
systems are available. If there is no storm or combined sewer available
for such drains, then the water from said drains shall be conducted
by proper pipe or pipes below the surface of the sidewalk to the street
gutter or to a place of disposal satisfactory to the administrative
authority, and in accordance with any other plans or ordinances adopted
under the Storm Water Management Act, 1978, October 4, P.L. 864, No.
167,[1] or other ordinances or regulations of the municipality
involved. In no case shall collected surface water or stormwater be
allowed to drain over sidewalks or driveways.
[1]
Editor's Note: See 32 P.S. § 680.1 et seq.
Stormwater shall not be drained into sewers intended for sewage
only.
Storm drains, conductors, traps, fittings, etc., shall be of
materials as provided for in Article V of the Allegheny County Plumbing
Code, Materials Standards and Areas of Permitted Use, provided that
Schedule 40 or stronger pipe is used across backfill areas.[1]
[1]
Editor's Note: See Ch. 860, Plumbing and Building Drainage,
in the Allegheny County Code.
Size of building storm drain. The size of the building storm drain or any of its horizontal branches having a slope of 1/2 inch or less per foot shall be based upon the maximum projected roof or paved area to be handled according to the following table of size of horizontal storm drains. (See § 186-7B.)
A.
Where required. All buildings shall be provided with proper conductors
for conducting the water from the roofs in such manner as shall protect
the walls and foundations of said buildings from injury.
B.
Not to be used improperly. Conductor pipes shall not be used as soil,
waste or vent pipes, nor shall drainage or vent pipes be used as conductors.
C.
Outside conductors and connections. Outside conductors may be of
sheet metal or other approved material, but they must connect to the
storm drainage piping by extending the pipe at least one foot above
grade level. All outside sheet metal conductors shall be connected
to the pipe as direct as possible, in a vertical position, and no
sheet metal conductor shall be run horizontally across the outside
walls of a building.
Every sump or receiving tank receiving the discharge of clear
water such as rainwater, subsoil or seepage drainage, shall be of
materials as provided for in Chapter 860, Article V, Materials, Standards
and Areas of Permitted Use, of the Allegheny County Code.
A.
Sump pump systems. A sump pump system shall include the sump pump,
pit, discharge piping and an individual branch electrical circuit.
The system shall include a pump of a capacity and head appropriate
for anticipated use requirements.
B.
Sump pit. Size shall be as recommended by the sump pump manufacturer.
The pit shall be topped by a removable cover adequate to support anticipated
loads in the area of use. The pit floor shall provide permanent support
for the sump pump. The pit shall be constructed of tile, concrete,
steel, plastic or other approved material.
C.
Discharge piping. Where discharging into a storm or sanitary sewer
system, a suitable antisiphon device or free-flow check valve shall
be installed. Where discharge to separate sanitary and storm sewers
is required, two independent sump pump systems are required. Discharge
pipe size and fittings shall be the same size as or larger than the
sump pump discharge tapping.
A.
When subsoil drains are placed under the basement floor or used to
encircle the outer walls of a building, they shall be protected by
an accessibly located backwater valve before connecting to the building
storm or combined drainage system. Where connected to separate storm
drainage system, and the connection is made on the building side of
the main leader trap, no other trap will be required other than the
backwater valve; where the connection is made on the sewer side of
main leader trap, they shall be effectively trapped, or they may discharge
into a properly trapped area drain or catch basin. Where connected
to a combined building drain, they may discharge through a cellar
or basement floor drain using a four-inch running trap provided with
an accessibly located backwater valve. These drains shall have a connection
of not less than four inches in diameter. Piping used for the collection
of subsoil or seepage drainage shall be of approved material as provided
for in Chapter 860, § 860-65, of the Allegheny County Code.
The pipe shall be laid on no less than four inches and covered with
no less than six inches of crushed stone or gravel of medium size
and arrangements made to cover the pipe with a material to prevent,
as much as possible, sand or dirt from washing into and clogging the
stone or gravel bed and cover.
B.
The table "Size of Vertical Conductors" shall be as follows:

Values for continuous flow. Where there is a continuous or semicontinuous
discharge into the building storm drain or building storm sewer, as
from a pump, ejector, air-conditioning plant, controlled-flow roof
drainage or similar device, each gallon per minute of such discharge
shall be computed as being equivalent to 24 square feet of roof or
paved area.
A.
Building subdrains located below the public sewer level shall discharge
into a sump or receiving tank, the contents of which shall be automatically
lifted and discharged into the drainage system as required for building
sumps.

C.
Protection of rainwater conducts. Rainwater conductors installed
along alleyways, driveways or other locations where they may be exposed
to damage shall be protected by metal guards, recessed into the wall
or be constructed of galvanized steel pipe to a height which will
afford the necessary protection.
D.
Combining storm with sanitary drainage. The sanitary and storm drainage
system of a building shall be entirely separate, except that, where
a combined sewer is available, the building storm drain may be connected
in the same horizontal plane through a single Y-fitting to the sanitary
sewer beyond the building wall on the sewer side of the sanitary building
trap. This requirement need not apply to single-family dwellings or
buildings with less than 2,600 square feet of roof drainage. Such
systems may be combined inside the building where separation of systems
would not be practical.
E.
Double connections of storm drains. Where the sanitary and storm
drains are connected on both sides of the combined sewer, single Y's
shall be used, and the requirements of § 860-169E of the
Allegheny County Code relative to the location of connections shall
also apply.
No portion of the storm drainage system installed underground
or below a basement or cellar shall be less than three inches in diameter.
Outside underground storm sewers shall be a minimum of four inches
in diameter.
A.
Material of roof drains. Roof drains shall be of materials as provided
for in Chapter 860, Article V, Materials, Standards and Areas of Permitted
Use, of the Allegheny County Code.
B.
Roof drain strainers, general use. All roof areas, except those draining
to hanging gutters, shall be equipped with roof drains having strainers
extending not less than four inches above the surface of the roof
immediately adjacent above roof level, of not less than 1 1/2
times the area of the conductor to which the drain is connected.
C.
Flat decks. Roof drain strainers for use on sun decks, parking decks
and similar areas normally serviced and maintained may be of the flat
surface type, level with the deck, and shall have an available inlet
area not less than two times the area of the conductor to which the
drain is connected.
D.
Roof drain flashings required. The connection between roofs and roof
drains which pass through the roof and into the interior of the building
shall be made watertight by use of proper flashing material.
Expansion joints or sleeves shall be provided where warranted
by temperature variations or physical conditions; such types of joints
or connections shall be subject to the approval of the administrative
authority.
Where separate systems of sanitary drainage and storm drains
are installed in the same property, the storm and sanitary building
sewers may be laid side by side in the same trench.
In lieu of sizing the storm drainage system from conventional
methods as previously described in this article, the roof drainage
may be sized on controlled flow and storage of the stormwater on the
roof, provided that the following conditions are met:
A.
The water of a one-hundred-year-frequency storm is not stored on
the roof for more than 24 hours.
B.
The water depth on the roof does not exceed three inches during the
above storm.
C.
The roof is dead level and forty-five-degree cants are installed
at any wall or parapet.
D.
Roof design for controlled-flow roof drainage shall be based on a
minimum of 30 pounds per square foot loading to provide a safety factor
above the 15 pounds per square foot represented by the three-inch
design depth of water. This factor should definitely be kept in mind
as a prime requirement for assuring a structurally sound roof.
E.
Flashing extends at least six inches above the roof level and scuppers
are placed in the parapet wall 3 1/2 inches above the roof level.
F.
No less than two drains are installed in roof areas 10,000 square
feet or less and at least four drains in roof areas over 10,000 square
feet.
G.
Control of runoff from flat roofs shall be by proportional weirs;
no valves or mechanical devices shall be permitted.
H.
Drainage from controlled flow which is based on gallons per minute
of flow shall be converted to equivalent square feet of roof or paved
area, on the basis of each gallon per minute of flow being equivalent
to 24 square feet of area, as provided in § 860-164D of
the Allegheny County Code. Drains not equipped with weirs, such as
area drains, may be connected to the controlled-flow system, provided
that the square feet of area, including the converted gallons-per-minute
flow to square feet, are added together and the drain is sized to
convey the sum of all loads in accordance with Tables 860-164A, Size
of Horizontal Storm Drains, and Table 860-164B, Size of Vertical Conductors,
of the Allegheny County Code.
I.
A sketch of the roof leader-yard piping arrangement shall accompany
the building permit application.
J.
Use Schedule 40 pipe to transport stormwater from conductors over
excavated areas in the proximity of the foundation.
