A. All four-inch, six-inch, eight-inch, ten-inch, and twelve-inch, inside
nominal diameter, ductile-iron, cement-lined pipe shall be Class 52
"Tyton" type joint, centrifugal cast pressure pipe for water. Sixteen-inch
ductile-iron, cement-lined pipe and twenty-four-inch ductile-iron,
cement-lined pipe shall be ductile iron Class 51. All such pipe shall
be ductile iron pipe centrifugally cast in metal molds or sand-lined
molds conforming to the latest edition of American National Standards
Institute/American Water Works Association (ANSI/AWWA) C151/A21.51.
The interior of the pipe shall be cement mortar lined in accordance
with the latest edition of ANSI/AWWA C151/A21.51 double thickness
and then seal-coated on the exposed surface of the lining with bituminous
coating. All such pipe used must be listed as ANSI/NSF 61 approved
in regard to coatings and cement linings. Any "Tyton" or "Super Bell-Tite"
type joint, ductile-iron pipe may be furnished in either eighteen-
or twenty-foot laying lengths. For any Pressure Class 350 ductile
iron pipe, the preceding shall apply, except that said pipe shall
be Pressure Class 350 in lieu of Class 52.
B. All four-inch, six-inch, eight-inch, ten-inch, and twelve-inch, nominal-inside diameter, polyvinyl chloride (PVC) pressure pipe shall be Class 150, and shall have a standard dimension ratio (SDR) of 18 and conform to the latest edition of American Water Works Association (AWWA) C900. The outside diameter of said PVC pipe shall be the same as that of the same nominal size of cast-iron or ductile-iron pipe so that no special adaptation is necessary to connect to cast-iron or ductile-iron valves and fittings. Said PVC pipe shall be only of integral bell and plain end lengths. The installed pipe shall be prepared for use, including hydrostatic testing, in conformance with the latest edition of Section
7 of AWWA Standard C605. All such PVC pipe shall be furnished with mechanical pipe (cast iron) gaskets. Detectable metallic underground tape, a minimum of two inches wide, marked for "Water" shall also be installed one foot above the top of any such PVC pipe.
C. All ductile iron fittings shall be in accordance with the latest
edition of American Water Works Association Standard Specifications
(AWWA C110) for ductile iron pressure fittings, mechanical joint,
short body fittings rated at 250 psi, American National Standards
Institute (ANSI) A21.10. All such fittings shall be tar-coated outside
and cement-lined inside in accordance with the latest edition of AWWA
Specification C104.
