What is backflow?
Backflow is water flowing in the opposite direction from its normal flow. CVWD potable water system is designed to keep the water flowing to our customers. When hydraulic conditions within any water system deviate from “normal,” the direction of water flow can be reversed. This creates a backflow condition and the potential for contaminated water entering the potable water distribution system.
