“Water is the driving force of all nature.” – Leonardo da Vinci
Water Plant Transmission Mains
Project Overview
To meet the growing need for clean, safe drinking water in central Ohio, the City of Columbus is building a fourth water plant along the Scioto River near the corner of Home and Dublin roads in Delaware County. Water transmission mains – two large pipes approximately 48 inches in diameter – will be built to directly connect the new Home Road Water Plant to the Columbus Water & Power water distribution system near the Blazer Parkway area and other strategic areas in northwest Columbus.
Columbus Water & Power currently provides an average of 149 million gallons per day (MGD) to residents of Columbus and more than two dozen other central Ohio communities. These needed improvements will provide additional water treatment capacity, increased reliability, and relief for the three existing Columbus water plants. The new plant will also provide additional capacity needed to address expected regional growth and demand.
The first engineering phase of the transmission mains project involved evaluating multiple corridors and narrowing them down to the most viable routes. The second engineering phase, currently underway, aims to identify the most feasible alignments based on ease of access for transmission main maintenance, business and residential impacts, availability of easements, environmental considerations, traffic and active transportation impacts, utility conflicts, overall costs, and other identified risks.

FIELD INVESTIGATIONS
Before the final transmission main alignments can be confirmed, survey crews need to conduct a series of investigations and field surveys. These investigations are occurring within road right-of-way areas and on some private property and continue through design of the project.
The City of Columbus is notifying impacted property owners and occupants by mailing notification letters. The City of Dublin is notifying residents about these activities on Nextdoor and other communication channels, and Concord Township is posting information on its website.
Sample notifications are shown below.
Weekly Field Activities
FIELD SURVEY & INVESTIGATIONS
Field Investigation | Begins Monday, August 3 | Between 7:00 a.m. and 7:00 p.m. | Survey Teams: ms consultants and Columbus Water & Power
Field crews will need to enter and survey the rear of private properties along the Ashbaugh corridor. Crews will examine updated landscaping, cleared honeysuckle, and removed or planted trees since the area was originally surveyed. No digging or equipment will be necessary. We do not need to enter any buildings on your property.

Field Surveys | Begins Monday, July 20 | Between 8:00 a.m. and 5:00 p.m. | Survey Teams: Gresham Smith and ms consultants
Field crews will conduct field walks to obtain data on the existing conditions across your property. This includes collecting information on existing fences, trees, and paths, as well as taking photographs. More than one entry may be required. The Water Plant Transmission Mains project team is also coordinating this effort with AEP officials.
