Public Water Systems: Reopening or Returning to Full Service
When a public water system (PWS) closes for an extended period of time, potable water can stagnate and deteriorate. This can occur within seven to nine days and result in disinfectant residual loss, microbial growth, sediment and metal accumulation, and disinfection byproduct formation.
The following resources provide guidance for PWS owners or operators returning to full service, including reopening a single-building water system like a school or reopening multiple buildings where a facility was closed or reduced in capacity.
PWS owners or operators should consult with their DEQ regional office or health district to coordinate reopening dates and requirements.
DEQ recommends all systems returning to full service collect total coliform samples prior to opening and collect compliance routine total coliform samples immediately upon opening.
