Unidirectional Flushing Class

Unidirectional Flushing Workshop

Periodic flushing of the water distribution system is one of the best methods  a utility can use to ensure that the water supplied to customers is plentiful and of good quality.  Unidirectional flushing uses the closing of valves to direct the water to hydrants at sufficient velocity to remove the sediment, debris and biofilms that can build up in the pipes over time.  In addition, this technique identifies problems such as closed valves and poor hydraulic capacity that, when corrected, greatly improve water quality and delivery.  Using unidirectional flushing techniques as part of an overall flushing program is a proactive way that the distribution system operator can keep the distribution system operating at peak efficiency. 

Whether you are looking to convert your current flushing program to unidirectional, or if you only want to supplement your program by doing unidirectional flushing in problem areas, this workshop is for you.  Subjects covered include basic distribution system hydraulics, flushing program objectives, tool and equipment requirements, valve and hydrant operation, flushing program design, data collection, customer relations and dechlorination techniques.  The students will practice what they learn by working together in small groups to design a unidirectional flushing plan for a small distribution system.

What our students are saying about this class

  • I have been in construction for over 25 years and your workshop was by far one of the best!
  • class was a good mix of book material and hands on.
  • liked most the development of the flush plan.
  • liked learning the procedure and steps of flushing a hydrant and how to improve our city flushing program.
  • instructor was great!
  • I liked learning how to design a flush, so we won't have to engage a consultant.
  • Great level of detail.  Provided insight that I can take back to work and use.
