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.

IMPORTANT  Plan Submittal Instructions

Ohio EPA Division of Drinking and Ground Waters is moving to a different platform, ePlan, for plan submission, review and approval. Public Water Systems and their representatives can begin using the ePlan platform starting today. On December 1, 2022, Ohio EPA DDAGW will no longer accept submissions through e-mail or Liquid Files. When plans are received, an invoice for payment of the review fee, along with the instructions on how to pay, will be sent to the party that submitted the plans. Review will begin when payment is received. 

Account Set Up and Plan Submission 

You can set up an account at: https://edocpub.epa.ohio.gov/PlanReview

Through this account you will submit your engineering plans, Project Summary Sheet, applicant and project information and any other supporting documents.
