How We Disinfect a New or Repaired Waterline in San Diego County

Any new water main, service lateral, or repaired section of existing pipe in San Diego County must be disinfected before it is placed back into service. We isolate the section, introduce chlorine to the concentration specified by AWWA C651, and hold for the required contact time so the entire interior surface is treated.

Once the hold time is met, we dechlorinate to neutralize residual before discharge, flush the line with potable water, and coordinate bacteriological sampling through our state-certified laboratory partner so your San Diego County purveyor has everything needed to clear the line for service.

Flushing & Flow Testing

Lines are flushed with potable water until chlorine residual and turbidity fall within acceptable range before sampling begins.

Bacteriological Sampling

Coordinated collection and chain of custody through our state-certified lab partner confirms the line is safe before release.
