When a load of pipe arrives at the job site, it is your responsibility to check it thoroughly. If possible, inspect each piece for damage. Check quantities against the shipping list. Note that the policy of most pipe manufacturers is that once the pipe leaves the manufacturer’s plant, it becomes the property of the shipping company. Any damaged or missing items should be documented on the bill of lading. Set aside any damaged items and notify the shipper.
Various parameters must be considered when designing a buried piping system. Two of the main considerations should be the pipe properties and the soil envelope around the pipe. To the layman, the word “soil” can mean different things. To engineers involved in pipe burial, soil is any earthen material excluding bedrock.Soil has been used as a construction material throughout history. Soil is important not only as a material upon which the structure rests, but also for support and load transfer. The soil envelope transfers surface and gravity loads to, from, and around the structure.

This paper addresses the inaccurate hydraulic claims made by the Ductile Iron Pipe Research Association (DIPRA) and shows that when industry-accepted data are used, PVC pipe is more energy efficient, cost effective, and sustainable than ductile iron (DI) pipe. DIPRA maintains that DI pipe has lower pumping costs than PVC pipe. The claim is that DI’s larger inside diameters (ID) offset PVC’s better flow characteristics. However, DIPRA’s brochures and on-line calculator contain misleading information and erroneous hydraulic assumptions, generating biased results.

This document covers PVC and PVCO pressure pipe for potable water, reuse water, and sanitary force main systems; and PVC nonpressure pipe for gravity storm water and sanitary sewer systems. All pipes are made in lengths that are assembled at the job site. Each length has a belled end with a elastomeric gasket such that each pipe length’s spigot end fits inside the belled end of the next pipe length.
