Water Districts
Look Up Which Water District Serves Your Harris County Address
TCEQ's Water Districts Map Viewer lets you search any Harris County address to find which water or utility district supplies it.
Harris County has hundreds of water-related special districts — MUDs, Water Control and Improvement Districts, and others. Each has its own tax rate, service area, and debt level. Knowing which one serves your address matters when buying a home.
Go to tceq.texas.gov and use the Water Districts Map Viewer. You can search by address or zoom in on a map. Once you find the district, you can look up its registered agent, current status, and contact information. This is especially useful for homes in newer subdivisions on the county's edge, where MUDs are common.
