Why are fire hydrants flushed during this process?

Local water providers (cities or utility districts) who receive North Texas Municipal Water District (NTMWD) water may help move the chlorine-disinfected water through the system faster by flushing water out of fire hydrants. Frequent flushing helps maintain the system, ensure high water quality, and reduce the chlorine odor and taste. Performing system flushing in the spring also helps save valuable water during the summer months.
