Notifying all DC Water customers of a water or sewer emergency is one of our highest priorities, but specifically knowing where critical customers are and how to communicate with them assists the whole community in being resilient and in protecting susceptible populations. Emergency notifications are a time sensitive endeavor, and it is important for us to be able to contact critical customers quickly. Filling out the critical customer sign-up helps us by providing up to date locations and contact information for a crucial customer facility.
