City Rolls Out New Water Supply Protection Device Program

Published : Monday, May 27, 2019 | 6:30 AM

City health officials last week described a new public water supply protection program being rolled out which should eliminate the potential for a contamination problem called backflow.

The program’s new devices will cost property managers $75 per device, the City said, based on the equipment or activity located on each property.

Pasadena Public Health Director Dr. Ying-Ying Goh said the Public Health Department has established a Cross Connection Program in accordance with California Code of Regulations Title 17 Section 7584, which requires the installation of a backflow prevention device in premises where the customer’s system has more than one service connection, or contains a cross-connection or the potential for a cross-connection that could result in the pollution or contamination of the water system in the event of a backflow.

A cross connection is the point at which a potable water system connects with non-potable water, gas, or other substances. Backflow occurs when water is allowed to flow in the opposite direction, which may pull contaminants or pollutants into the drinking water supply.

A backflow prevention device ensures the flow of water is not reversed during an event of low pressure in the system.

The City’s Cross Connection Program will provide surveys of water user premises to identify hazards, track annual device test results and routine repairs, and provide oversight and inspection during phases of construction, according to the City announcement.

Owners or managers of an industrial, commercial, institutional, or residential property that requires one or more backflow prevention devices will receive an invoice of $75 per device, in accordance with Section 116800 of the California Health and Safety Code, and with approval by City Council in the City’s general fee schedule.

For any questions about the Cross Connection Program, call the Environmental Health Services Division of the Pasadena Public Health Department at (626) 744-6004.
