Cross Connection Control Program
The City of Cambridge Water Use By-Law requires that properties must be surveyed for cross connections every three years to ensure backflow preventers are installed to protect the municipal water supply. All testable backflow preventers must be tested annually.
Primary contacts and property owners can access their cross connection file information and upload Surveys and Test Reports by selecting My Files.
Plumbing contractors licensed by the City of Cambridge can upload Surveys and Test Reports by selecting Upload Backflow Prevention Reports.
