Sewers and Appurtenances
Sewers shall be constructed of reinforced c<:>ncrete sewer pipe con-
forming to the following specifications and in accordance with detailed Plans
attached hereto.
Des cription
The reinforced concrete sewer pipe shall be made in sections of not
less than eight and one-half (8-1/2) feet in length and so formed that when the
sections are laid together and joints filled with joint material they shall make
a continuous and uniform line of pipe with a smooth and regular interior sur-
face, and strength test requirements for the different strength classifications
as shown On the following table. All pipes shall he marked with the date of
their manufacture and no pipe shall be laid that is not at least fourteen (14)
days old.
Design Requirements
The strength test requirements in pounds per linear foot of pipe under
the three-edge bearing method shall be either the D-Ioad (test load expressed
in pounds per linear foot per foot of horizontal diameter) to produce a 0.01 inch
crack, or the D-Ioads to produce the 0.01 inch crack and the ultimate load as
specified below, multiplied by the internal diameter of the pipe in feet.

Materials
The reinforced concrete shall consist of Portland cement, mineral
aggregates and water, in which steel has been embedded in such manner that
the steel and the concrete act together. The aggregates shall be so sized and
5
so graded and proportioned and thorougW.y mixed in a batch mixer with such
proportions of cement and water. as vv.i.ll produce a homogeneous concrete mix-
ture of such quality that the pipe will conforni to the des ign requirements
enumerated heretofore. The mixture shall contain not less than six U. S.
Sti::mdard bags (94 pounds) per cubic yard of concrete. The minimum compres-
sive strength of the concrete at the time of acceptance shall be as follows:

Cause for Rejection of Pipe
Pipe shall be subject to rejection on account of failure to meet any of
the specification requirements or on account of any of the following imperfections:
1. Fractu:'''es or cracks passing through the shell, except that a sin-
gle end crack that does not exceed the depth of the joint shall not be cause for
rejection. If a single end crack that does not exceed the depth of the joint
.existsin more than 10% of the pipe inspected; however, the defective pipe will
be rejected.
2. Defects which indicate imperfect mixing and molding.
3. Surface defects indicating honeycombed or open texture.
4. Spales deeper than one-half the depth of the joint or extending
more than four (4) inches around the circumference exist in more than 100/0
of the pipe; however, the defective pipe shall be rej ected.
5. Exposure of the circumferential reinforcement indicating mis-
placement of the reinforcement.
Inspection
