Water flows to taps through pressurized pipes. Normally it flows only in one direction but in certain circumstances, it can backflow, or travel in the opposite direction. When backflow occurs, the flow of water or other substances from a customer's plumbing goes into the District's water distribution system. It is a hazardous situation that can threaten the safety of the water supply. Backflow prevention devices are required on properties where there is a potential for this to occur. Also, all sites that use recycled water for irrigation must have an approved backflow device installed. Backflow prevention devices must be tested annually. To protect the water supply, the District is constantly on the lookout for backflow situations.
