  • When will service be restored?
    BWS crews work to restore water service as quickly and as safely as possible. It is difficult to estimate when service can be restored, however, because we may need to address unforeseen issues and need to make water system adjustments before restoring service.
  • The road is clear. Why isn't my water back on?
    For some repaired mains, especially along coastal areas or near streams, additional water quality testing may be necessary. This process can take up to 24 hours to complete. During that time, customers affected by the break will typically have access to water wagons until testing is finished.
  • What if I have concerns after a main break repair is finished?
    See answers for frequently asked questions after a main break repair is completed.
