Reporting Water Emergencies
For after-hours or weekend water emergencies (such as main breaks, service leaks, valve or hydrant damage, and pressure issues), call our emergency line. A Central Control Operator will assess the issue, initiate a work order, and dispatch crews if needed. Non-emergency issues will be handled during regular business hours.
Customer Water Supply Gate Valve
Every home or building has a water supply gate valve, used to shut off water during repairs or emergencies. Locate this valve in advance, and ensure everyone in your household knows how to use it, to prevent leaks and flooding.
Where to Find Your Gate Valve:
-
Near the Front of the House – Where the water supply pipe enters your home, often below the hose bib (garden hose attachment).
-
Inside the Meter Box – Located near the front of your home. If the gate valve is inside, it will be on the side of the meter closest to your house. (Do not use the Angle Stop or Meter Valve, which are water company property, to turn off water.)
If you cannot locate your gate valve, contact Customer Service during normal business hours for further assistance.
