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 – large pipes approximately 42-60 inches in diameter – will be built to directly connect the new Home Road water plant to the Department of Public Utilities water distribution system near the Blazer Parkway area and other strategic areas in northwest Columbus.

These needed improvements will provide additional treatment capacity, increased reliability, and relief to the three existing Columbus water plants. Once the new plant and water transmission mains are operational, overall system capacity will increase to meet the needs of the public. The current average daily volume required by the public is 145 million gallons per day (MGD) and is expected to increase to 175 MGD in the near future. This additional demand will be partially met by the new Home Road water plant.

Route alignments for the water transmission mains have not yet been determined. Phase 1 of the project will identify, evaluate and select up to three route alignment alternatives based on the accessibility of the water mains, business and residential impacts, availability of easements, environmental impacts, traffic and active transportation impacts, utility conflicts, overall costs, and other identified risks.

FIELD INVESTIGATIONS

Before new transmission main locations 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 throughout 2025.

The City of Columbus is notifying adjacent property owners and occupants by mailing notification letters. The City of Dublin is assisting with this effort and also notifying residents about these activities on NextDoor and other communication channels.

Sample notifications are shown below.

FIELD SURVEY & INVESTIGATIONS

TOPOGRAPHIC & PROPERTY SURVEYS | Monday, March 3 through Friday, April 11 | 7:00 a.m. and 7:00 p.m. | Survey Team: Resource International

Two-man field crews will conduct field investigations to perform topographic and property surveys near planned transmission main corridors in Concord Township and the City of Dublin. Crews will be within the road right-of-way and will need to access private properties to complete this work. We do not need to enter any homes. Letters were mailed to affected property owners and residents.

Below are the approximate survey locations:

Concord Township:

  • Concord Road/Harriot Road intersection
  • AEP Easement corridor between the Concord Road/Harriot Road intersection and Cook Road
  • The eastern end of Cook Road and the intersection with Dublin Road

City of Dublin:

  • Blazer Parkway, south of Rings Road
  • Rings Road/Woerner Temple Road, from Blazer Parkway to Parkwood Place
  • Parkwood Place, from Woerner Temple Road to Emerald Parkway
  • Property near Emerald Parkway south of US 33
  • Coffman Park, near Emerald Parkway and Post Road
  • Coffman Road, south of Brand Road
  • Property north of Coffman Road and Brand Road
  • Brand Road, near Bristol Parkway and Ashbaugh Road
  • Ashbaugh Road

WATER WELL COLLECTION | Thursday, March 20 | 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.

SOIL TESTING | Wednesday, March 19 through Friday, April 19 | 7:00 a.m. and 7:00 p.m. | Survey Team: KTA
 
Two two-man crews will conduct these investigations, beginning at the north end of the Phase 1 alignment (Dublin Road and Concord Road in Concord Township) and ending at the south end (Rings Road and Blazer Parkway Dublin).
 
Testing involves four narrow pins that will be driven into the ground, and a special meter will record the measurements. Each test should take less than 15 minutes. No permanent impact to yards or property is expected. Crews will be within the road right-of-way of the City of Dublin and Concord Township and we will need to access private property to complete this work. We do not need to enter any homes, and traffic impacts are not expected.
 
In addition to fieldwork within the jurisdiction right-of-way, private property will need to be accessed in the following areas:
 
Concord Township:
  • AEP Easement corridor between the Concord Road/Harriot Road intersection and Cook Road
City of Dublin:
  • Quantum Health property on the north side of Rings Road
