Public Works defends chlorine-conversion runs as water-saving step; dialysis patients cautioned
Summary
Public Works described multi-week chlorine-conversion operations to reduce biofilm and reported roughly 20 million gallons saved during conversion runs; staff advised dialysis patients to consult physicians about timing.
Scott Christen explained the city's chlorine-conversion program, which temporarily switches disinfection from a chloramine blend to free chlorine to reduce biofilm in buried pipes and reduce the need for high-volume flushing. He said prior trials achieved biofilm control within three weeks and that the program reduces wasted water during summer months.
"Last year alone, we calculated approximately 20,000,000 gallons saved," Christen said, citing the benefit of reduced flushing. He said residents may notice slick or cloudy water for short periods during conversions and that staff publish notices and advisories; Christen recommended dialysis patients contact their doctors for precautions and said most dialysis patients use distilled water as standard practice.
