In order to provide our customers with a plentiful supply of high quality water, Greater Cincinnati Water Works (GCWW) optimizes water treatment processes and operations and proactively replaces more than 30 miles of aging water mains each year. These enhancements also improve water flow and pressure. At GCWW, we strive to be a leader in regional solutions.
GCWW Water Main Replacement Projects:
GCWW has several Water Main Replacement Projects ongoing throughout the city. The list below provides information about specific projects that may impact your area. Click on the link for more details about the project.
Why are we investing?
Water mains are usually expected to last 80-120 years. As part of the annual replacement program, investments are being made to provide the most reliable service to our customers.
Benefits Include:
- Fewer potential water main breaks or leaks
- Improved water system reliability
- Increased water supply
- New fire hydrants

Mt. Airy Water Storage Facility Rehab Project
Greater Cincinnati Water Works has initiated a design-build project with Dugan & Meyers to rehabilitate the Mount Airy Water Tanks, which is nearly 100 years old. Phase 1 of the project is to evaluate the existing conditions and develop a rehabilitation design, has a budget of up to $3.8 million, and will continue into 2026. Phase 2 of the project will follow Phase 1 and be the construction phase of the project. Based on the Phase 1 work completed to date, a preliminary cost estimate for the Phase 2 construction is $40 million. In addition to the rehabilitation project, a community engagement and feasibility study for alternate site uses is in progress.

Limited Environmental Review and Finding of No Significant Impact
No ID, No Entry:
If someone comes to your door and says they are with the Greater Cincinnati Water Works, ask for identification. Our Field Personnel wear blue or brown uniforms with patches on their hats and sleeves that read "Cincinnati Water Works." Each employee also carries a picture ID. GCWW sometimes uses contractors for certain services, including our meter change-outs. Our contractors will have a GCWW ID as well as their company ID. Always ask to see the ID before you let anyone into your home.
