Engineering

Ohio’s public water systems (PWSs) provide an invaluable service and vital resource to the populations they serve. Chapter 6109 of the Ohio Revised Code authorizes Ohio EPA to safeguard public health by enforcing requirements of the Safe Drinking Water Act. The Division of Drinking and Ground Waters (DDAGW) oversees the operation and permitting of PWSs, which partially includes the review of engineering plans.

To ensure that adequate quantities of safe drinking water are provided, DDAGW staff review engineering plans and other information pertinent to proposed PWS projects. The division also develops engineering guidance documents, collaborates with the Ohio Section of American Water Works Association and reviews PWS backflow prevention and cross-connection control programs.

For more information or questions about engineering considerations for PWSs, please contact your DDAGW district office or call DDAGW Central Office at (614) 644-2752.
