Water Main Flushing Program

The 2020 Annual Water Main Flushing Program has concluded.  

The Annual Water Main Flushing Program typically begins in March and ends in May each year.  During this time, a slight change is made in the water treatment process to facilitate an effective flushing program. The purpose of this temporary change in the process is to help ensure a high level of disinfection in our community’s network of water mains.

During this period, customers may notice a slight chlorine taste and smell in their tap water. The difference in taste and smell is the result of a switch to disinfection using free chlorine, which is a more aggressive disinfectant than the chloramines used during the rest of the year. This temporary change in the water treatment process is important because it keeps bacteria from forming resistances to the usual disinfection process. 

From March through May, our crews will open hydrants throughout our service area in brief intervals in order to draw water more forcefully through the distribution system. This helps to dislodge sediment that may have collected in water mains over the past year. Crews will work each day, Monday through Friday (excluding holidays), from 7:00 a.m. until 3:30 p.m.

Customers are notified about the flushing program via bill insert and notices are posted in the local newspaper, The Free Lance Star.

Important Notice

During the flushing of the water mains in your immediate area, you may notice a temporary reduction of water pressure or some discoloration in your tap water. This discoloration condition is not harmful. This should clear up quickly by simply leaving your cold water running until it is clear after the flushing in your neighborhood is complete. We also suggest you do not wash clothes during these operations in your neighborhood. 

If discoloration persists, please call 540-507-7300, press option 2, Monday through Friday, 8:00 a.m. to 4:30 p.m, or after-hours/weekends/holidays, please call 540-507-7340 or 540-507-7350. 

Additionally, to reduce/prevent erosion problems, please check your culvert pipes and ditches to make sure they are free of leaves and debris. We appreciate your cooperation and we will endeavor to keep any inconvenience to a minimum.
