14. FOR IMMEDIATE RELEASE February 18, 2009 Newly-Named ‘Plumbing Efficiency Research Coalition’ (PERC) Identifies Drainline Transport as First Joint Project. CHICAGO, ILLINOIS (FEBRUARY 2009) — The newly-named Plumbing Efficiency Research Coalition, (PERC) formed last month through a Memorandum of Understanding (MOU), has identified Drainline Transport as its first research project. IAPMO’s Pete DeMarco will serve as project coordinator The Plumbing Efficiency Research Coalition was founded to develop research projects that will support the development of water efficiency and sustainable plumbing products, systems and practices. Projects will be financed through government grants, foundations and private financing. PERC - Plumbing Efficiency Research Coalition

15. The results of this project will provide the future criteria for the design of sustainable sanitary plumbing systems
