Many of the water mains in Lincoln are constructed of cast iron. Generally, short periods of rusty water may appear after a main has been shut down for repair or if a nearby hydrant has been used. You may try running cold water for several minutes (about 10) to clear the rusty water out of your service. If you are still experiencing rusty water, please call Lincoln Water System at 402-441-7571.
Other sources of rust could also be from your own service. If you have any galvanized internal lines or fittings, you can expect to have periodic episodes of discolored water, especially after a period of non-use. The water heater can also be a source of rusty-water problems. If only the hot water is rusty, that indicates that the problem lies in the water heater.
