Holistic Considerations for Stagnation in Plumbing

Stagnation in plumbing has been linked to a myriad of physicochemical and microbial water quality issues. While many studies on plumbing stagnation were conducted during the COVID-19 pandemic to assess real-time risk associated with building closures, these lacked control, knowledge of plumbing materials, and appropriate controls. This talk will highlight a study that used a fully controlled plumbing testing facility with four identical systems operated with daily, weekly, biweekly, and monthly flushing to assess the role of building operation in water quality changes holistically. Stagnation played a major role in scale formation, chemical leaching, and microbial community changes, with clear implications for sulfate metabolisms. By understanding these reactions mechanistically at-scale, we create a better context for controlling this sensitive ecosystem.

This series is open to the public, but non-PreMiEr members must register to receive the Zoom link. You need register only once for the entire series.
