United StatesEnvironmental ProtectionAgencyOffice of WaterWashington, 832-F-00-068 September 2000 WastewaterTechnology Fact SheetPipe Construction and MaterialsDESCRIPTIONT here are several different pipe materials availablefor Wastewater collection systems, each with aunique characteristic used in different four different pipe materials described in thisfact sheet are ductile iron, concrete, plastic, andvitrified material selection considerations includetrench conditions (geologic conditions), corrosion,temperature, safety requirements, and cost. Keypipe characteristics are corrosion resistance (interiorand exterior), the scouring factor, leak tightness,and the hydraulic manufacturers follow requirements set by theAmerican Society of Testing Materials (ASTM) orAmerican water Works association ( awwa ) forspecific pipe materials.
American Water Works Association (AWWA) for specific pipe materials. Specification standards cover the manufacture of pipes and specify parameters such as internal diameter, loadings (classes), and wall thickness (schedule). The methods of pipe construction vary greatly with the pipe materials. Some new pipe materials and construction methods
