Low-flow plumbing for green buildings could have water quality issues: study

A new study suggests that commercial buildings with low-flow water design could have safety issues when it comes to water quality, in part due to water sitting stagnant for longer periods of time.
Researchers studied the water quality in a three-storey commercial building in Indiana over three weekends between January and February 2020.
Their goal was to find out if water quality changed over the weekend when less people were in the building, and thus even less water than usual was moving through the pipes.
The answer appears to be yes, according to the findings published Wednesday in the journal PLOS Water.
“Weekend stagnation influenced chemical and biological water quality, with clear differences in several parameters on Friday, after a week of use, and Monday, after a weekend with relatively little use,” the study stated.
