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.

Weekly Field Activities

FIELD SURVEY & INVESTIGATIONS

WATER WELL COLLECTION | Wednesday, April 30 through Thursday, May 1 | 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.

FIELD SURVEYS & INVESTIGATIONS | Wednesday, April 2 through Friday, May 2 | 7:00 a.m. and 7:00 p.m. | Survey Teams: ms consultants, Gresham Smith, DLZ, Resource International, KTA, Stone Environmental, ASC Group, Ahlum & Arbor, and the City of Columbus

Several crews will conduct field surveys and investigations along the current planned transmission main corridor in the Earlington area within the City of Dublin. Investigations include field walks/site visits, topographic and property surveys, soil resistivity testing, and ecological, archaeological and tree surveys. 
 
Crews will be within the road right-of-way of the City of Dublin and will need to access private property to complete this work. We do not need to enter any homes, permanent impacts to yards or property are not expected, nor are traffic impacts expected. Letters were mailed to affected property owners and residents.
 
Below are the approximate survey locations:
 
City of Dublin:
 
  • Residences along Earlington Parkway (between Coffman Road and Dublinshire Drive)
  • Residences along Dublinshire Drive (between Earlington Parkway and Glanmore Court)
  • Residences on the east side of Glanmore Court
  • Residences on Brand Road (5775, 5705, 5675, 5615, 5565 and 5545)
  • Asherton of Dublin apartments
  • Dublin Baptist Church
  • Dublin Presbyterian Church

SUBSURFACE UTILITY ENGINEERING (SUE) INVESTIGATIONS | Monday, April 14 through Friday, May 2 | 7:00 a.m. and 7:00 p.m. | Survey Team: DHDC Engineering Consulting Services

Two, two-man crews will conduct these investigations along the northbound lane of Muirfield Drive, beginning from the south at the intersection with Crossgate Drive, and concluding in the north at the intersection with Whittingham Drive (Franklin County line) in the City of Dublin.

All fieldwork investigations will occur within the public right-of-way of the City of Dublin. Traffic impacts are not expected. Thru traffic and property access on Muirfield Drive will remain open, and no roadways will be closed.

  • SUE investigations include the identification, location, and mapping of underground utilities, such as water lines, gas pipes, electrical conduits, and communication cables, to ensure that future construction activities do not inadvertently damage these assets.
  • These investigations will allow the project team to collect reliable and accurate underground utility information, eliminate future utility conflicts, and enhance overall safety during project construction.
  • There are four recognized quality levels of underground utility information ranging from Quality Level (QL) D (the lowest level) to Quality Level A (the highest level).
  • Our field crews will be conducting Quality Level A, which provides information for the precise plan and profile mapping of underground utilities through the exposure of underground utilities and provides the type, size, condition, material, and other characteristics of underground features.
  • Quality Level A involves the excavation (drilling) of test holes by a two-man excavation crew and a vacuum truck. These test holes are typically 12 inches in diameter, with a depth of no more than eight feet. Following the field investigation, each test hole will be backfilled and repaved daily according to the approved permit.

TREE SURVEY | Friday, April 4 through Friday, May 9, 2025 | 7:00 a.m. and 7:00 p.m. | Survey Team: Ahlum & Arbor

Field crews will be in your area to conduct a tree survey along the current planned transmission main corridors. Arborists will conduct field walks to develop and document a tree inventory. This includes identifying each tree’s species, size (diameter), and condition. We do not need to enter your home or building.

TOPOGRAPHIC & PROPERTY SURVEYS | Monday, April 21 through Friday, May 16 | 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:
