White Papers & Studies

Get the latest research from The IAPMO Group.

IAPMO research provides strategic insights to advance policy on clean drinking water and safe sanitation. Instead of simply looking at a problem, our staff and members — many times in partnership with communities or other professional organizations — study and research issues affecting health and environmental impacts of changing plumbing, mechanical, alternative energy, and water systems, and how they affect our daily lives. In many cases, there are unintended consequences that also require consideration in developing optimal solutions. The IAPMO Group believes in sharing our knowledge through industry studies and white papers, because safety belongs to everyone.

Peak Water Demand Study

IAPMO and ASPE, long with funding from the Water Quality Research Foundation (WQRF), convened a special task force to revise the methodology for properly estimating premise water supply demands in response to the increased use of water-conserving plumbing fixtures, fixture fittings and appliances and the subsequent decreased demand for water in commercial buildings and residences. The charge of the task group was to develop a statistically based probability model that would predict the peak water demand for single and multi-family dwellings having water-conserving plumbing fixtures.

The Drainline Transport of Solid Waste in Buildings – Phase 2.0

Potential blockages in commercial building drain lines have been feared by plumbers and building managers due to increasingly efficient plumbing fixtures. The Plumbing Efficiency Research Coalition (PERC) identified this issue as a critical research need, and undertook an earlier phase of this study to examine the behavior of drain lines under certain conditions. This report is the second part of that study evaluating the characteristics of transport of solid waste in commercial building drains.

The Drainline Transport of Solid Waste in Buildings

With the enactment of the Energy Policy Act of 1992, all water closets (toilets) manufactured in or imported into the United States were required to flush no more than a maximum average of 1.6 US gallons (6.0 Liters), effective January 1, 1994 for residential models and January 1, 1997 for all other models. After these new models were introduced into the marketplace, a significant number of consumers reported poor flush performance. This prompted some early reporting and research on the first generation of 1.6 gallons per flush (gpf) (6.0 Liters per flush – Lpf) water closet models.

Storm Drainage System Research Project

It was brought to the attention of the American Society of Plumbing Engineers Research Foundation (ASPE RF) that a number of failures with storm drainage systems had occur red. The types of failures included: Collapse of roof Pipe fitting separating Hanger pulled from prestressed concrete floor/ceiling Flooding of upper-level balcony decks Fitting component failure Flooding in the building on upper floors due to pipe failure

EPA Decentralized Plumbing Webinars

EPA's Decentralized Wastewater Management Memorandum of Understand (MOU) Partnership sponsors periodic webinars to discuss issues of interest to the decentralized community. Below are presentations, transcripts, and speaker lists from each of the webinars.
