Hydrant Flushing Program

SCWA conducts its Hydrant Flushing program throughout our system starting in March and continuing until the fall.  Under the program, fire hydrants will be opened in order to remove sediment, reduce rust complaints and improve water quality.  It is also a test of a hydrant’s operation to ensure a sufficient water supply is available for fire protection.  Areas are flushed by zip code on a predetermined schedule.
