Plumbing Efficiency Research Coalition (PERC) Releases Long-Anticipated Results of Drainline Transport Study
Chicago, Ill. (November 26, 2012) The Plumbing Efficiency Research Coalition (PERC) is pleased to announce that the long-anticipated study, The Drainline Transport of Solid Waste in Buildings, has been released and is now available on the PERC Website: http://www.plumbingefficiencyresearchcoalition.org
. The study provides important insights into the performance of building drains and addresses opportunities for future research.
PERC was formed in January 2009 through a Memorandum of Understanding (MOU) to develop research projects that support the development of water efficiency and sustainable plumbing products, systems and practices. Projects are financed through government grants, foundations and private financing. The Coalition is comprised of industry organizations seeking to conduct much-needed research in a number of areas. PERC identified drainline transport as its first research project.
The six members of the coalition are represented by Mary Ann Dickinson, Alliance for Water Efficiency (AWE); Jim Kendzel, American Society of Plumbing Engineers (ASPE), Pete DeMarco, International Association of Plumbing and Mechanical Officials (IAPMO); Jay Peters, International Code Council (ICC); Gerry Kennedy, Plumbing-Heating-Cooling Contractors National Association (PHCC); and Barbara C. Higgens, Plumbing Manufacturers International (PMI).
Its critically important that we gain a better understanding of how building drains perform as flows from plumbing fixtures, appliances and commercial equipment are reduced and toilet fixtures become increasingly stressed to singularly transport solid waste to sewers. This study identifies the controllable variables in the building drain system, such as slope, flush volume, toilet paper selection and toilet discharge attributes, and examines their relative significance on performance. says DeMarco, who acted as the technical director for the study.
