There are common misconceptions among design engineers regarding pipe stiffness, pipe
deflection, impact strength, abrasion, and design life when comparing PVC and fiberglass
(FRP) sewer pipes. When correct evaluations are done, PVC is the product of choice.
The Health, Safety, and Environmental Performance of PVC PipeManishPatel169454
PVC pipe is extensively utilized worldwide for water and sewer systems, owing to its proven track record of health and safety. Throughout its more than 70 years of use, PVC pipe has undergone rigorous evaluation and approval processes by governmental and accredited third-party testing and certification agencies. These assessments have consistently demonstrated that PVC pipe is a safer and healthier option compared to pipes made from alternative materials.
introduction to molecular oriented polyvinyl chloride pvco pipeManishPatel169454
The manufacturing process for PVCO causes realignment of the molecular structure
from random orientation to circumferential orientation. This increases the material’s
mechanical strength and toughness. Once completed, PVCO pipe has an HDB of 7,100
psi. Owing to PVCO’s different HDB values, the dimension ratio (DR) classification for
conventional PVC is not used for PVCO. Instead, PVCO is referenced only by pressure
class (PC) or pressure rating (PR).
This document covers PVC pressure pipe for potable water, reclaimed water, and sewer forcemain systems; and PVC non-pressure pipe for storm sewer 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.Environmental Product Declaration Program Operator

hydraulic analysis pumping costs for pvc and ductile iron pipeManishPatel169454
This paper confronts the misleading hydraulic assertions put forth by the Ductile Iron Pipe Research Association (DIPRA) and demonstrates that, when utilizing industry-accepted data, PVC pipe emerges as more energy-efficient, cost-effective, and sustainable compared to ductile iron (DI) pipe. DIPRA contends that DI pipe incurs lower pumping costs than PVC pipe, attributing this to DI's larger inside diameters (ID) compensating for PVC's superior flow characteristics. However, the brochures and online calculator provided by DIPRA contain misleading information and flawed hydraulic assumptions, ultimately leading to biased results.
When it comes to selecting pipe for your trenchless application, there is no shortage of options — steel, iron, clay, concrete and plastic. Given the plethora of choices, the decision of which pipe to use for your project can be daunting. What you need is information on what each pipe brings to the table. To help you out, Trenchless Technology contacted pipe associations and manufacturers of the eight pipes typically used in trenchless projects to point out what their particular conduit offers. The information presented is intended to provide just a preliminary glimpse at the different pipe on the market. For more etail information, please contact the manufacturer, pipe association or your consulting engineer. All information presented was provided by the various pipe associations or manufacturers.
This document has been developed by the Uni-Bell PVC Pipe Association for design and installation of
PVC fittings where solid-wall PVC pipe is used in non-pressure applications.
The guide provides information on the wide range of fittings that are available for various dimension
ratios and outside diameters of PVC pipe through 60-inch.
Also included is information on installation practices that are intended to optimize the performance of
PVC fittings.
Wastewater conveyance generally falls into two categories: gravity flow and pressure flow. The mostcommon way to transport wastewater is through downward-sloped pipe by gravity flow.
When gravity sewers are not possible or economically practical, pressure from a lift station is used to convey wastewater through a pipe known as a “force main.”

ENVIRONMENTAL PRODUCT DECLARATIONS FOR UNDERGROUND PIPINGManishPatel169454
Assessment of environmental claims for materials and
products used in underground piping infrastructure can be a
daunting task, since there are many widely varying methods
that can provide contradictory results. The most logical
way to ensure valid sustainability assessment is to use an
internationally recognized, third-party certified method like
an Environmental Product Declaration (EPD).

municipal procurement competitive bidding for pipes demonstrates significant ...ManishPatel169454
In 2013 the Mayors Water Council (MWC) released “Municipal Procurement: Procurement Process Improvements Yield Cost-Effective Public Benefits”, a report examining procurement practices in the water infrastructure sector. The report made a business case for considering alternative pipe material so local governments could realize public benefits (e.g., cost, performance, safety). The report suggested the need to change outdated procurement policies, and that the biggest impediment to adopting these changes stemmed from the reluctance of local procurement officials to break from convention.This report presents information from new research that demonstrates the merits of adopting open procurement policies and new practices that apply competitive consideration of alternative pipe materials. These policies will help local officials maximize
resources and practice good governance.

American cities, adopting the use of advanced technology and better approaches to clean water and sewer are common and often required by law. Cities providing public water delivery have not only grown in population size and in number, but also in their attitudes toward public health, and innovations involving system
designs, technologies and accepted practices. In the 19th century cast iron was added to the common use of clay, lead and wooden pipes by cities to convey water and wastewater. In the 20th century, continued innovation carried ductile iron, concrete
and cement, and plastic pipes into the market. In the 21st century, new generations of plastics, advanced composites, and other materials are being added to a long list of
viable piping materials. Technological advancements in pipe materials have helped to support a growing national population while continuing to improve on cost and performance and achieve public health protection goals to guard against waterborne
parasites and toxic contaminants.
