WebSep 5, 2024 · As that slug of water flows through the piping at a given velocity, it will begin to take with it any residual debris of a certain size existing in the piping. The higher the velocity of the slug of water, the larger the debris it can transport. This is the rationale behind the NFPA 13 and NFPA 20 flushing velocity requirements. WebApr 13, 2024 · During the flushing process crews open strategically located hydrants throughout the water distribution system to let water flow at a high velocity through pipes for several minutes to remove natural sediment. Crews will de-chlorinate the water as it leaves hydrants in order to remove the disinfecting agent in the water – chlorine – so that ...
WebOct 7, 2016 · Unidirectional Flushing. UDF isolates each pipeline to create flow in a single direction to quickly and efficiently clean the pipe. By concentrating flow, UDF creates higher velocities that are better able to clean the pipe. The cleaned mains may have improved water clarity or color, reduced turbidity and improved chlorine residual. WebMar 2, 2024 · A faster valve will allow more cleaning gas to scour the inside of the pipe at maximum velocity. A quarter-turn ball valve or knife gate valve that opens in 0.5 to 1 …
