Water Plant Transmission Mains

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.
