PVC pipe is one of the safest and most tested materials used in North America. For over 60 years, every aspect of its production, use and disposal has been evaluated and approved by government and independent certification and testing agencies.
It meets or exceeds all required health and safety standards and regulations governed by the U.S. and Canadian Safe Drinking Water Acts and other international statutes.
PVC Pipe meets all required health and safety standards and regulations governed by the U.S. Safe Drinking Water Acts and other international statutes.
PVC pipe requires less energy and fewer resources to manufacture and its production creates virtually no waste.
The Uni-Bell PVC Pipe Association (PVCPA) has published the first North American industry-wide environmental product declaration (EPD) for water and sewer piping, and it has been verified by NSF Sustainability, a division of global public health organization NSF International.
The EPD was developed in compliance with international environmental management guidelines (ISO 14025) and benchmarks the impacts of seven PVC pipe products across their life cycles. This includes PVC pressure pipe for potable water, reclaimed water and sewer force main systems as well as PVC non-pressure pipe for storm sewer and sanitary sewer systems. NSF Sustainability reviewed and verified the life cycle assessment (on which the EPD is based) and EPD documents to ensure that no unsubstantiated claims were made and that the EPD followed all applicable rules.

There are several methods for restraining PVC pipe joints.To keep pipe joints from pulling apart, either joint restraint or concrete thrust blocking is required.
Dynamic Ground movement is one of the items utilities should consider when choosing pipe materials for their water and sewer systems. Movement can be caused by a slowly eroding hillside, intermittent freeze/thaw and wet/dry cycles, or a sudden cataclysmic earthquake.
The PVC Pipe Association has re-issued its “Tapping Guide.” The new guide includes additional diagrams and photos, as well as expanded text — all in a more logical, readable format. For those unfamiliar with the term, “tapping” refers to drilling a hole into a main-line pipe to attach a branch line. The process is often done with the main line under full pressure, so specialized techniques have been developed to streamline the installation process.
Life cycle cost analysis is presented
as a financial decision tool for pipe
replacement selection by applying
the findings of reliability and
longevity research and testing. This
combination of pipe examination
and testing data in conjunction with
previous pipe break studies supports
PVC as a sustainable pipe material,
confirming a 100+ year benchmark
as an industry standard.

Instead the new system provides a minimum wall thickness table combined with minimum pipe stiffness values – the pipe manufacturer is now able to provide the targeted pipe stiffness with any combination of wall thickness and modulus of elasticity (as long as material cell class and minimum wall thickness requirements are met).

Internal Pressure Design Calculator
This calculator enables engineers to determine PVC pipe pressure class and wall thickness for various internal pressure limit states. The user inputs values for the three pressure design checks found in Chapter 5 of the Handbook of PVC Pipe Design and Construction and the acceptance test requirement in accordance with AWWA C605. Designers are responsible for the proper use of this program for all projects. The design checks are as follows:
Our mission is to promote use of longer-life, lower-maintenance, corrosion-proof PVC piping in water and wastewater systems – for real sustainability, strength and long...
