If you live on the Eastside, your water bill comes from one of several local providers. Knowing which one serves your address saves time when you need to report a problem, ask about a leak adjustment or set up service after a move. This guide sticks to what the utilities themselves publish.
How Bellevue Gets Its Water
Bellevue Utilities says its water comes from the Cedar River and Tolt River watersheds in the Cascade Mountains. The city buys that water through Cascade Water Alliance, a regional wholesaler that was formed in 1999. Cascade lists Bellevue, Issaquah, Kirkland, Redmond, Tukwila, Sammamish Plateau Water and Sewer District, Skyway Water and Sewer District and Covington Water District among its members.
Cascade buys its supply from Seattle under a long term agreement, and Bellevue Utilities then delivers it to homes and businesses. In other words, Cascade is the wholesaler and Bellevue Utilities is the company that reads your meter and sends your bill.
Water Service In Bellevue
Bellevue Utilities retails water to more than the city itself. Its service area includes Clyde Hill, Hunts Point, Medina, Yarrow Point and sections of Kirkland. Coal Creek Utility District serves portions of Newcastle and Renton and says its northern boundary is the Bellevue city limits.
If you are unsure who serves you, check your bill first. Then use that provider's published service area map or contact page to confirm.

Who Bellevue Utilities Serves
The city says its water service area covers more than 37 square miles. It includes Clyde Hill, Hunts Point, Medina, Yarrow Point and sections of Kirkland, in addition to Bellevue itself. That means a Kirkland mailing address does not always mean a Kirkland water bill, and the reverse can be true elsewhere on the Eastside.
The simplest way to confirm your provider is to look at the most recent water bill. The name at the top tells you who to call about service, billing and leaks.
Where Coal Creek Utility District Fits
Coal Creek Utility District is a separate special purpose district. It says it serves portions of Newcastle and Renton, and that its northern boundary is the Bellevue city limits at Southeast 69th Street. The district says all of its water supply is obtained from Seattle Public Utilities, so it does not buy water through Cascade.
The district's own history says it was formed in November 1959 from two older water districts, and that Bellevue assumed the part of the district inside its limits effective December 31, 2003. If you live near the Newcastle border, check the district's service area map or your bill rather than guessing from the street address.
Which Pipes Are Yours
Utility ownership matters for plumbing repairs. Bellevue Utilities says leaks at or beyond the point where your line connects to the city's system are the customer's responsibility. That includes the buried service line that runs from the meter to the house, which many homeowners never think about until it fails.
For sewer, Bellevue's code says side sewers on private property belong to the property owner, who is responsible for maintaining and repairing them. The city owns the sewer facilities in the public right of way. If your address is served by a different utility, ask that utility where its responsibility ends.
Using Your Meter To Spot A Problem
Bellevue's electronic meters show a FLOW icon when water is moving through them. If every fixture is off and FLOW is still showing, you may have a leak. The meter shows LEAK once water has flowed nonstop for at least 24 hours, and it takes one full hour without flow for that message to clear.
The city's customer portal also shows hourly usage and sends leak alerts. Continuous 24 hour usage is described by the city as a strong sign of a leak. If you see it, shut off the main valve and call a plumber, then ask your utility whether any billing adjustment applies.
Moving Between Utilities
If you move between a Bellevue Utilities address and an address served by a district or another city, plan to set up service with the new provider directly. Billing, account numbers and customer contact details are separate. Ask the new provider what it needs from you and when service starts, so you are not left without water on moving day.
Water quality reports are published by each provider. If you have a question about taste, hardness or treatment, read your own utility's current report or ask the utility directly, rather than relying on a general comparison between systems.
When To Call A Plumber Instead
Call your utility for billing questions, meter readings and problems on the street side of the meter. Call a plumber for leaks on your side, low pressure inside the house, water heater trouble and anything that involves the pipes you own. If you are not sure which side the problem is on, our leak detection team can trace it and tell you where the failure sits.
We serve Bellevue and the surrounding Eastside, including Newcastle and Renton, so the provider on your bill does not change how we diagnose the problem. For burst lines and active leaks, see our burst pipe repair page.
