Over the summer months, the Fire Department will flow-test hydrants in Winnetka. Data obtained from this process ensures the hydrants are in good working order and provides hydraulic information to both the Fire Department and Water & Electric Department. Signs will be placed in testing areas.
During flow testing, sediment accumulations are removed from the water system. You may notice water discoloration for a brief period after a flow test in your area. While the water is safe to drink, it can discolor laundry. If this occurs, run the faucet for several minutes or until the discoloration subsides. If the water does not become clear after this procedure, please contact the Water Department at 847-716-3558.
