Manitowoc Public Utilities will begin unidirectional flushing (UDF) this coming week.
UDF is a method used to clean and improve the carrying capacity of the city’s water distribution system.
This cleaning method helps MPU continue to provide safe, high-quality drinking water to residents and businesses.
When performing UDF, staff open and close pre-determined valves in order to isolate a specific section of water main.
This section of main is then flushed by opening a specifically-selected fire hydrant that will draw water through the now-isolated section of water main.
Since the water main is isolated and is only being fed from one direction, the speed of the water flowing through the isolated section of main is greatly increased, producing a scouring effect.
The scouring effect removes any potential sediment build-up and cleans the water main.
