The Prince William County Service Authority is conducting its Water Distribution System Spring Cleaning Program. 

Customers may notice a slight chlorine taste and smell in their tap water through early summer. 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 late March through June, Service Authority crews 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.
