Richmond Hill's Cross Connection Control Survey Report, the Maintenance & Operations Division form issued under Backflow Prevention By-law 125-14. It records the facility address, type of water use (industrial, commercial, institutional or multi-residential), overall hazard level, size of service and metering, the qualified person and facility contact, and a numbered table of each cross connection with its hazard level, existing protection, serial number, last test date and recommended upgrade. A code list names each type of backflow preventer. It is the survey companion to the Backflow Preventer Test Report.
