(OLNEY) The City of Olney Water Department will be switching the disinfectant in Olney’s water distribution system from the regular combined chlorine to free chlorine this coming Monday, April 2. The switch is for maintenance purposes and is in conjunction with the City’s biannual hydrant flushing program. It’s at this time that the residents of Olney may notice a stronger chlorine smell while the free chlorine is being used. The City’s water flushing will begin a week from this Sunday night, on April 8. The City of Olney and its Water Department appreciates the patience and understanding of all City of Olney water customers while the treatment process continues throughout the City over the next couple of weeks.
