When to call which utility
Use this District utility map before a job changes a meter, service mast, service drop, gas appliance, water line, sewer lateral, trench, sidewalk, areaway, alley, vault, driveway apron, or exterior structure. For outages, meter pulls, temporary power, service upgrades, underground work, solar interconnection, EV chargers, or a panel job that requires a utility disconnect, start with Pepco for the exact premise. For gas odors, hit lines, meter relocations, pressure questions, appliance conversions, or boiler work, stop work and call Washington Gas or 911 from a safe distance when there is an immediate leak. DC Water coordinates taps, meters, hydrants, backflow, sewer laterals, main shutoffs, and service-line ownership. DDOT public-space permits can control sidewalks, alleys, vaults, dumpsters, cranes, curb cuts, and staging even when the work is on private property. DCSEU is the energy-efficiency and rebate channel, not an outage utility, but it can affect contractor selection for heat pumps, insulation, and appliance incentives. Before excavation, boring, fence posts, tree planting, sewer, water, drainage, or sign work, file the 811 ticket through https://www.missutility.net/ and wait for marks or positive response. Record the ticket number. Public marks do not replace private locating for owner-installed lighting, irrigation, drains, or lines beyond the meter.
811 comes before utility-side work
File a locate request before trenching, boring, planting, fencing, drainage work, sewer work, or water-service changes. Utility marks do not replace private locating on owner-installed lines.
