Why are backflow prevention devices required on homes on the harbor channels?
A. Homes on the harbor channels are one of several potential health hazards to the drinking water supply. California Health Code Title 17 specifically addresses “dockside watering points” or “marine facilities” requiring backflow protection. Boat docks are unique in that there are many activities which require water use in potentially hazardous ways, such has bilge or sewage pumping, refilling onboard water tanks, or even a garden hose accidentally left in the sea water. Many homes have previously been built without protection and will be required to install the appropriate device, once they have been inspected by Cross Connection Control and have been notified to make the correction. If you suspect that your home should have backflow protection, please call to get more information.
