“Water is the driving force of all nature.” – Leonardo da Vinci
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 SURVEY | Begins Monday, March 2nd | 7:00 a.m. and 7:00 p.m. | Survey Team: ms consultants
Field crews will conduct field walks to obtain stream data on private property within Concord Township. This work includes measuring the length of the stream, evaluating the stream hydrology and taking photographs. Fieldwork will occur on or after March 2, and crews will not need to enter any homes.
Private properties affected include:
- 9747 CONCORD RD
- 7178 HARRIOTT RD
- 7220 HARRIOTT RD
- 6970 HARRIOTT RD

- 6398 COOK RD
- 6300 COOK RD
- 6386 COOK RD
- 6404 COOK RD
- 6468 COOK RD
- 6278 COOK RD
- 8656 DUBLIN RD
- 6580 COOK RD
- 6385 HOME RD
- 6490 COOK RD
Private property owners were mailed a letter on Monday, February 23, detailing this work. AEP representatives have been notified as fieldwork will be conducted within the AEP corridor.

WATER WELL COLLECTION | Thursday, March 19th | 7:00 a.m. and 7:00 p.m. | Survey Team: Eagon & Associates
We will be collecting water levels at previously installed monitoring wells along all WPTM alignments. All testing will occur within the public right-of-way of the City of Dublin and Concord Township.

Subsurface Field Investigation | Begins Monday, March 23rd | Between 9:00 a.m. and 4:00 p.m. | Survey Teams: Granite Geophysical, LJB Underground Services, ms consultants and Columbus Water & Power
Field crews will conduct subsurface field investigations within the public right-of-way of the City of Dublin along Coffman Road (from Tara Hill Drive to Earlington Parkway) and Earlington Parkway (from Coffman Road to Asherton Boulevard). This fieldwork includes a Multichannel Analysis of Surface Waves (MASW) survey, a non-invasive, passive method that uses surface waves to identify subsurface soil and rock conditions such as the depth to bedrock, and soil strength and stability. Teams will not impede any emergency services that may need to reach your property.

TREE SURVEY | Beginning Tuesday, March 17th | 7:00 a.m. and 7:00 p.m. | Survey Team: Ahlum & Arbor
We will be conducting a tree survey at a private field adjacent to Emerald Parkway and near Perimeter Drive south of Coffman Park, owned by the Thomas family, beginning Tuesday, March 17.
