A » Unidirectional Flushing (UDF) is a water main cleaning technique that involves strategically closing valves and opening hydrants to create a single-direction, high-velocity water flow. This process effectively removes sediment and debris, improving water quality and maintaining system integrity. Unlike conventional flushing, UDF is more efficient as it isolates specific sections, ensuring thorough cleaning and minimizing water waste.
