II, (AS SET OUT IN INDOT STANDARD SPECIFICATIONS).
REINFORCEMENT IN THE "C" PORTION SHALL BE THE SAME AS SPECIFIED FOR
REINFORCED CONCRETE, A.S.T.M. DESIGNATION C-76 CLASS II, FOR THE SIZE OF
CONNECTING PIPE.
REINFORCEMENT IN THE "B" PORTION SHALL HAVE A CROSS SECTIONAL AREA
EQUAL TO THAT OF ONE LAYER OF STEEL IN THE "C" PORTION.
THE END OF THE PIPE CULVERT SHALL BE PLACED IN THE CONCRETE END SECTION
SO THAT THE FLOW LINES ARE FLUSH. THE JOINT SHALL BE COMPLETELY FILLED
WITH MORTAR.
IN 3:1 OR 4:1 FILL SLOPE, CHANGE TO THE SLOPE OF THE END SECTION IN A
SMOOTH, PLEASING TRANSITION APPROXIMATELY 10'-0" IN LENGTH.
VARIATIONS IN DIMENSIONS - THE THICKNESS OF THE CONCRETE, THE POSITION OF
STEEL, AND THE INTERNAL DIAMETER OF THE PIPE SHALL CONFORM WITH THE
VARIATIONS IN DIMENSIONS AS PROVIDED IN THE SPECIFICATIONS FOR
REINFORCED CONCRETE CULVERT, STORM DRAIN, AND SEWER PIPE, A.S.T.M.
DESIGNATION C-???
WHERE VITRIFIED CLAY CULVERT OR CAST IRON CULVERT PIPE IS USED, A "PIPE
END SECTION" COMPARABLE TO THAT AS SHOWN FOR METAL OR CONCRETE SHALL
BE FURNISHED AND SHALL BE AS APPROVED BY THE ENGINEER, EXCEPT IN AREAS
OF ACID OR MINE WATER THEN THE USE OF METAL END SECTION IS PROHIBITED.
END SECTIONS WILL BE PAID FOR AT THE CONTRACT UNIT PRICE EACH FOR "PIPE

REQUIREMENTS FOR ALL STORM SEWER BENCHWALLS
BENCH WALLS SHALL BE SHAPED AND FORMED FOR A CLEAN TRANSITION WITH PROPER
HYDRAULICS TO ALLOW THE SMOOTH CONVEYANCE OF FLOWS THROUGH THE MANHOLE
OR BOX INLET. THE BENCH WALL SHALL FORM A DEFINED CHANNEL, TO A MINIMUM
HEIGHT OF 80-PERCENT OF THE INSIDE DIAMETER OF THE INLET AND OUTLET PIPES TO
FORM A "U" SHAPED CHANNEL, CONSTRUCTED AT A MINIMUM ½-INCH PER FOOT SLOPE
TO THE MANHOLE WALL.
WHERE A FLOW CHANNEL IS CONSTRUCTED AS AN INTEGRAL PART OF THE PRE-CAST
BASE, IT SHALL BE SHAPED AND FORMED AS DESCRIBED ABOVE, WITH THE EXCEPTION
THAT THE BOTTOM OF THE FLOW CHANNEL MAY BE FORMED FROM THE BOTTOM OF
INLET AND OUTLET PIPES IF THE PIPE WALL THICKNESS IS NOT GREATER THAN ONE (1)
INCH.
FOR CAST-IN-PLACE FLOW CHANNELS, THE BOTTOM INVERT OF ALL PIPES ENTERING A
MANHOLE SHALL BE AT LEAST THREE (3) INCHES ABOVE THE TOP OF THE BASE SLAB TO
THE OUTLET INVERT SO THE FINISHED SEWER CHANNEL MAY BE INSTALLED AND
SHAPED.
FOR CONNECTIONS TO EXISTING STORM SEWER STRUCTURES, FLOW CHANNELS SHALL
BE SHAPED, AS SPECIFIED HEREIN, AS IF IT WERE A NEW MANHOLE OR BOX INLET
STRUCTURE.
SPECIFICATIONS FOR ALL STORM SEWER CASTINGS
ALL STORM WATER INLETS AND CATCH BASINS SHALL HAVE THE WORDS "NO DUMPING,
DRAINS TO STREAM", OR SIMILARLY APPROVED MESSAGE, CAST IN RAISED OR
RECESSED LETTERS AT A MINIMUM OF 1" IN HEIGHT. IN ADDITION, A SYMBOL OF A FISH
SHALL ALSO BE CAST WITH THE LETTERS.
