To augment and complement the ice pigging, the City will be conducting another water line cleaning process, Line Swabbing, along the water mains feeding the water lines through out the City.
Line Swabbing requires the water line be taken out of service during the cleaning process, therefore customers will experience a water supply outage during this time.
Following the line swabbing process, the water line will be disinfected with a chlorine solution in accordance with regulatory requirements before being returned to service. Due to the water line temporarily being out of service during the swabbing process and in accordance with state guidelines, the City of St. Cloud Environmental Utilities Department is required to issue a “Precautionary Boil Water Notice” immediately following the Line Swabbing. The City of St. Cloud advises that all water used for drinking, cooking, making ice, brushing teeth, or washing dishes be boiled. A rolling boil of one minute is sufficient. The “Precautionary Boil Water Notice” will remain in effect until a bacteriological survey is completed and we have received results confirming that the water is safe to drink in the areas that have been affected. This process normally requires approximately two days. A separate notification will be issued to the customers that are affected when this process has been completed.
