Customers who get their water from Winnsboro might need to take some precautions when the town hooks onto the Columbia water system next week.
Columbia water, which is expected to start flowing through the pipes Tuesday, uses chloramines for disinfection, while the town of Winnsboro’s system uses free chlorine. Chloramines can cause problems with dialysis machines and fish tanks. Special filters are needed for those devices to remove chloramines.
Winnsboro had to turn to Columbia water as a stop-gap measure because drought and development have depleted the Winnsboro reservoir. The town supplies water to much of Fairfield County and portions of the Blythewood area.
