r <br /> • SECTION 6 <br /> WASTEWATER AND RECLAIMED WATER FORCE MAINS <br /> .. DUCTILE IRON PIPE AND FITTINGS <br /> 6.01 SCOPE <br /> This section covers cast ductile iron pipe and fittings for wastewater and <br /> reclaimed water force mains . <br /> 6.02 GENERAL <br /> A. Ductile iron pipe shall be allowed for use as wastewater and <br /> reclaimed water force main pipe where compatible with the <br /> specific conditions of the project. The use of material other than <br /> ® ductile iron may be required by Indian River County Department of <br /> Utility Services ( IRCDUS) during construction permit review or by <br /> IRCDUS field personnel during construction if it is determined that <br /> �. ductile iron pipe is unsuitable for the particular application . <br /> B . All ductile iron pipes shall be manufactured in accordance with <br /> r, AWWA Standard Specifications C150/A21 . 50-96 and C151 /A51 - <br /> 96, or latest revisions , and shall be pressure Class 300 or 350 <br /> minimum as depicted on Table 6 . 1 on page 6-2 . All ductile iron <br /> r <br /> pipes crossing under roadways shall be pressure Class 350 <br /> minimum . <br /> C. Unless specifically indicated otherwise, underground piping shall <br /> r be bell and spigot and aboveground piping shall be flanged . <br /> D . Cutting of ductile iron pipe shall be by sawing . <br /> r <br /> 6.03 PIPE <br /> .. Ductile iron pipe shall be bell and spigot cast in accordance with AWWA <br /> Standard Specifications C150/A21 . 50-96 and C151 /A51 -96 , or latest <br /> revisions . Cast ductile iron pipe shall have a minimum tensile strength of <br /> r 60 , 000 psi with a minimum yield strength of 42 , 000 psi . Pipe wall <br /> thicknesses shall be computed in accordance with AWWA Standard <br /> Specification C150/A21 . 50-96 , or latest revision , using the physical <br /> characteristics cited above with a minimum working pressure of 200 psi <br /> and a Laying Condition 'Type 2 . " Unless otherwise indicated or specified <br /> herein , the pipe shall have the minimum wall thickness according to class <br /> designation for diameters shown . All pipe shall be given a minimum <br /> factory hydrostatic test of 500 pounds per square inch . <br /> r <br /> r <br /> 6 - 1 <br />
