How water works in Westminster and beyond
Westminster's border is a patchwork. It butts up against Broomfield, Northglenn, Federal Heights, Arvada and Thornton, with pockets of unincorporated Adams and Jefferson County. An address that reads as 'Westminster' by mail can sit outside city services, so the local water and sewer names aren't guaranteed at the fringes.

Moving into Westminster, whether you're near Standley Lake or off the US 36 corridor, here's the order that keeps your first week from turning into a scramble:
Xcel Energy handles both electricity and natural gas across Westminster. It showed up at every address we sampled, which lines up with most of the Denver metro. Colorado doesn't have retail energy choice, so there's no competing supplier to pick between; you just open an Xcel account for the address. Water runs through Westminster Water and sewer through the City of Westminster, so those are separate setups, not part of the energy bill.
Sewer service comes from the City of Westminster, which runs it as a municipal, city-owned service. Water shows up under the name Westminster Water at every sampled address. Near the edge of town an address can land differently, so it's worth confirming the exact spot with the lookup rather than assuming. Electricity and gas, meanwhile, stay with Xcel regardless of where in Westminster you are.
Plan on more than one call. Energy is the simple part. Xcel provides both your electricity and gas across Westminster, and with no retail choice in Colorado there's no supplier to shop for. Water and sewer are handled by Westminster Water and the City of Westminster, so those get arranged on their own. Start with the lookup to confirm exactly who serves your address, then line up each account ahead of your move-in date so nothing lapses.
99% of Westminster electric checks pointed to Xcel Energy, making it the clear local answer.
The fastest path: look up the address, then open accounts in the checklist order. Electric first when timing is tight.
