The City of El Dorado Water Treatment Plant will be switching to free chlorine this week. This is a normal annual activity recommended by the Kansas Department of Health and Environment in order to maintain the highest water quality for our customers. The water is safe to drink and the chlorine odor you may notice, should be gone in a few weeks. If you have questions, please contact us at 321-9100 and ask for Judy McIntosh or Kurt Bookout.
