How fast do you flush in order to scour your mains?

• A. 1 foot per second
• B. 2.5 feet per second
• C. 5 feet per second
• D. 7 feet per second

Answer: (B)

In order to effectively scour water mains and remove sediment and buildup, a flushing velocity of around 2.5 feet per second is generally considered optimal. This flow rate is sufficient to create the necessary turbulence within the pipes, which helps to dislodge deposits without causing excessive wear or damage to the infrastructure. Flushing at this speed strikes a balance between adequate scouring and operational safety. Higher velocities could potentially result in issues, such as water hammer effects or damage to pipe materials, while lower velocities may not be effective enough to clean the mains properly. Therefore, a flushing speed of 2.5 feet per second is recommended for ensuring thorough cleaning of water distribution systems.
