Backflow Prevention


Preventing backflow is an important way the Public Works Department protects our drinking water.

Prevention & Protection

To prevent and protect against backflow, the Kimberly Public Works Department:

  • Requires backflow prevention devices to be installed and tested on all new construction.
  • Enforces annual testing on all water connections classified as high-hazard for backflow, including:
    • Commercial
    • Industrial
    • Residential properties


Backflow prevention devices prevent water from being pulled back into the drinking water system. By stopping the water, the device also stops the fertilizers, herbicides, pesticides, insecticides, industrial chemicals, bacteria, detergents, or other hazards that may be carried with the water.
