Water Plant Transmission Mains

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 156 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.

Public Meeting #2 

Learn the latest about the new Home Road Water Plant and Water Plant Transmission Mains projects.  The public meeting presentation is available to review from the December 3, 2024 public meeting.

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.
