Welcome to the eAR Portal

Our Electronic Annual Reporting (eAR) System is released for general use by California's public water systems. The eAR Portal serves water system staff upload documents and complete the required annual report. The information collected is necessary for legislative policy making, regulatory compliance, and sanitary inspections. Please visit the Water Board's Division of Drinking Water's eAR webpage for additional information.

Please provide all feedback, questions, or comments to DDW-eAR@waterboards.ca.gov. Thank you for your cooperation in using this reporting system.
