Advancing Water System Science, Research and Safety
The Environmental Science, Policy, and Research Institute (ESPRI) is now part of the IAPMO family, enhancing our research capabilities and commitment to public health. ESPRI is a nonprofit research organization dedicated to developing best practices for building water systems — from multifamily residences and hospitals to office buildings and schools. It connects institutions focused solely on drinking water, wastewater, or stormwater by integrating building water systems into the broader water cycle. Through collaboration with water utilities, regulators, building owners, and occupants, ESPRI works to ensure water remains safe all the way to the tap.
Now integrated within IAPMO's Technical Services and Research team, ESPRI supports innovation and evidence-based policy through IAPMO's Innovation and Research Fund — furthering our shared mission of protecting public health and ensuring a safer, more sustainable built environment.
Developed by ESPRI
ESPRI was the project lead on the Water Research Foundation's national-scale study on the occurrence of Legionella pneumophila in public water system distribution systems. The study filled a critical knowledge gap through the collection and analysis of more than 9000 water samples drawn from the distribution systems of 57 utilities.
Developed by ESPRI
ESPRI developed a white paper for ASDWA outlining the knowledge skills and abilities (KSAs) required for building water system operators for buildings designated as public water systems. Buildings that conduct supplemental treatment to their supplied water are considered public water systems (under the Safe Drinking Water Act).

ESPRI prepared this memo to help educate managers and staff who will flush building water systems about risks that some of them might face and to pass on a suggestion for reducing risks based on an experimental setup in their lab.
