The International Association of Plumbing and Mechanical Officials (IAPMO®) and the Environmental Science, Policy, and Research Institute (ESPRI) are seeking the public’s initial input for development of the Manual of Water Quality for Plumbing Industry Professionals and Building Managers.
This publication provides basic guidance to help plumbing system design engineers, building owners, and water system managers obtain important information from their water suppliers (public water systems; water suppliers or purveyors) to help them design, install, and manage potable water systems that maintain water quality all the way to the end users while simultaneously protecting the pipes, fittings, fixtures, and other components that make up these systems.
“ESPRI is dedicated to working with utilities, design engineers, plumbers and building operators to promote high water quality to all points of use and for all water system users,” said Dr. Tim Bartrand, ESPRI executive director. “We hope this guidance will assist the engineers, plumbers and operators working on the building side of the meter to better understand the water quality of their supply and how to control and monitor it. Together, the water supply and building water communities can advance public health goals while improving the sustainability of building water systems. ESPRI is grateful to IAPMO for its partnership in developing this guidance and its efforts toward building a bridge between the water supply and building water communities,”
IAPMO encourages the industry to provide comments to the latest draft, which can be obtained through this URL.
“IAPMO is always willing and grateful to collaborate with industry partners on getting critical information into the right hands,” said Christoph Lohr, PE, vice president of Technical Services and Research. “With ESPRI working in conjunction with IAPMO the ability of both organizations to further address water quality concerns in the plumbing industry is greatly amplified. We are excited about this initial public review draft for this water quality manual and continuing to this kind of critical work with ESPRI.”
Please provide your comments to christoph.lohr@iapmo.org by no later than July 17. For questions, please contact Lohr at (909) 731-0219 or via email.
