Illinois American Water will place signs in the neighborhoods where flushing is occurring. While the flushing program is underway, customers may experience a slight drop in water pressure or temporary water discoloration. Customers should refrain from doing laundry during the time of day the flushing program is taking place in or near their neighborhood. If tap water is discolored, it is recommended that several cold-water faucets are allowed to run for a short time until the water runs clear. Using more than one faucet allows the water to clear faster.
