Lake Charles residents may notice low water pressure later this month when the city begins changing its water system from a chlorine-ammonia system to a free chlorine system.
Free chlorine systems are designed to improve water quality by reducing the occurrence of biofilm and nitrification in the water system.
The process is expected to last about 60 days.
During that time, officials say residents may notice open fire hydrants in the city. They may experience lower water pressure, temporary water discoloration or a chlorine odor. Officials say the water will be safe to drink and, in most case, such problems should clear quickly by flushing water lines.
