Water Systems Geographic Reporting Tool
Welcome to the California Environmental Health Tracking Program's Drinking Water Systems Geographic Reporting Tool, also known as the Water Boundary Tool (WBT). The WBT facilitates the creation and collection of customer service area boundaries for public water systems in California.
Notification: The WBT is currently undergoing an upgrade. During this time, some features may not function completely. This may include registration, drawing features, and data downloads. Please contact us if you have any questions or need assistance during this time.
CEHTP is a collaboration between the Public Health Institute and the California Department of Public Health. CEHTP developed the WBT with initial funding from the CDC's National Environmental Health Tracking Program.
