New guide addresses stagnant water in buildings with low occupancy
At a time when many buildings are not fully occupied due to COVID-19, the American Water Works Association (AWWA) and the International Association of Plumbing and Mechanical Officials (IAPMO) have developed a guide to help building managers address water system stagnation.
Stagnation within building water systems is a concern in periods of low or no occupancy. When water does not move through the system, water quality issues may arise at an outlet, a group of outlets or throughout an entire building water system, causing potential health risks.
