In Dallas, electric delivery is handled by Oncor — and since Dallas sits in Texas's deregulated market, you pick your own Dallas retail plan; Atmos Energy is Dallas's natural-gas utility; Dallas Water Utility handles Dallas's water and sewer. The exact lineup depends on your Dallas address — even nearby Irving and Garland answer differently.

Dallas proper stretches across five counties, and the city's utility picture is cleaner than its suburbs': one wires company for electricity, one gas utility, one city water department. The confusion usually comes from moving between Dallas and its ring of suburbs, several of which run their own municipal utilities with different providers a few blocks apart.
One Dallas quirk worth knowing: the city's sheer north–south stretch means it borders more than a dozen suburbs, and every one of those borders is a potential provider change. White Rock Lake to the Cedars may share one lineup, but step over into the first ring of suburbs and the water bill changes hands.
The age of your Dallas address tells you which accounts to open first. Prewar bungalows in the M Streets and Winnetka Heights, and the postwar ranches spread across Casa View and Casa Linda, were largely built around gas — furnaces, water heaters, sometimes the stove — so the Atmos Energy account deserves the same attention as the electric one. Much of the newer apartment stock near the Katy Trail and downtown runs all-electric, and plenty of renters there never open a gas account at all. Whatever the building, mind the calendar: a July or August move here means triple-digit afternoons, and you want Oncor's wires delivering power before the truck pulls up, not after — a closed-up Dallas house in high summer takes hours to cool back down.

Oncor is the TDU for Dallas — the wires-and-meters utility — at every one of the Dallas addresses we sampled. You pick the retail plan that sets your Dallas rate; Oncor delivers either way.
At every one of the Dallas addresses we sampled, Dallas Water Utility was the water provider — sewer included. Other districts take over around Dallas's edges, so check your block.

Yes — Dallas Water Utilities is the City of Dallas's own water and sewer operation, and it served every Dallas address we sampled, for both services. You set up service through the city rather than a private company.
Often not. Garland next door runs its own municipal electric utility, several suburbs run their own water departments, and the gas utility can change as you cross county lines. Treat each suburb as its own answer — or just check the address.
Yes — Dallas sits in the part of Texas where electricity is a choice market, so the retail plan on your bill is one you pick yourself.
