Fire Hydrant Inspection


Horsham Water and Sewer Authority (HWSA) performs annual fire hydrant inspections.  Hydrant inspections are typically performed in the spring and occur between the hours of 8:00 AM and 4:00 PM. 

The inspection program is slightly different from our fire hydrant flushing program.  Inspections are performed to ensure the overall health of a hydrant.  Annual inspections improve our distribution system, water quality and most importantly promotes public safety in the event of an emergency.  During the inspection program, a strategically selected group of hydrants go through a vigorous health check which includes the following steps:

  • Exercising valves to ensure they are in good working order
  • Take and record measurements
  • Remove and grease all applicable parts
  • Perform static pressure
  • Open and close the hydrant
  • Check for drainage and leaks
  • Perform a minimal flush (different from the flushing program)
  • Visually inspect the hydrant for painting, obstruction, and height complications
  • Create a record of all data collected

Inspections do not typically alter water appearance because the volume of water used at the hydrant varies greatly opposed to the water used during the hydrant flushing program.  Nevertheless, residents may experience changes in water appearance and/or pressure changes in and around targeted work areas.  If work crews are visible in your area, it is recommended that customers refrain from using water and doing laundry.   HWSA encourages customers to look for changes in water appearance prior to each use.  Should discolored water persist outside of scheduled work hours, you may wish to flush your homes plumbing system for a few minutes. This should be done running COLD water from the lowest fixture.  This will typically relieve any trapped air or sediment.   If water variations persist, please contact the Authority at 215-672-8011.
