Unidirectional Flushing Run Data Collection Form

Captures operational data for each unidirectional flushing run, including valve sequencing, target velocity, chlorine residual, turbidity, and completion notes.

Run Identification

• Run Date
  Date the flushing run was performed.
• Run Start Time
  Time the flushing run began.
• Run End Time
  Time the flushing run ended, if completed.
• System Zone / Area
  Identify the flushing zone, pressure district, or area served.
• Hydrant or Outlet ID
  Unique identifier for the flushing point.
• Run Status
  Current status of this flushing run.

Valve Sequencing and Operations

• Valve Sequence Summary
  Briefly describe the valve opening and closing sequence used for this run.
• Upstream Valves Opened
  Select all upstream valves opened for the run.
• Downstream Valves Closed
  Select all downstream valves closed to direct flow.
• Total Valves Adjusted
  Number of valves opened, closed, or otherwise adjusted during the run.

Flushing Performance

• Target Velocity
  Planned flushing velocity for the run.
• Target Velocity Units
  Units used for the target velocity.
• Actual Velocity
  Observed flushing velocity achieved during the run.
• Actual Velocity Units
  Units used for the actual velocity.
• Flushing Duration (Minutes)
  Total active flushing time for the run.

Water Quality Measurements

• Chlorine Residual Type
