Due to the recent drop in temperature the Zone II Unidirectional Flushing Program has been restricted to cul-de-sac’s  and dead end water mains only.

Beginning Monday, October 29th flushing will originate on Maynard Road and include only cul-de-sac’s and dead end water mains. The flushing route will travel from Maynard Road heading southeast to Hudson Road and continue northwest toward the lakes region.

Why is flushing necessary? As an essential part of our system’s maintenance program during the spring and fall of each year, Sudbury Water District opens hydrants in an effort to clear our  water mains of sediment and mineral build up. This practice not only extends the life of our water mains but improves water quality.

To cleanse our distribution system, hydrants are systematically opened to increase flows, allowing the accumulated mineral sediment to “flush”  from the pipes. Though flushing won’t interrupt your water service, when crews are working in your area, you may notice a temporary drop in water pressure or discolored water. This is normal. After flushing hours (M-F 9 a.m. – 3 p.m.) or occasional evenings (after 8 p.m. only when noted) simply run a cold faucet briefly until the water runs clear, drawing out sediment from your service line.
