2. Fourth Water Plant Site Preparation

CIP 690600-100002

The City of Columbus currently owns and operates three water plants, collectively supplying an average of 145 million gallons per day of drinking water to Columbus and surrounding Central Ohio communities. The continued growth of population and industry in Central Ohio, along with the need to increase reliability and resiliency across the water supply system, has driven the need for additional water capacity. To meet these needs, the City will be constructing a new fourth water plant, also known as the Home Road Water Plant (HRWP).

Design of the new water plant was initiated in winter 2023 by the Department of Public Utilities (DPU) with the goal of bringing the new facility online by the end of 2030. The new water plant will be built on DPU-owned property along the Scioto River near the corner of Home and Dublin roads in Delaware County (view map(PDF, 777KB)). Additional information about the project can be found at https://cbuswater.com/.

Once operational, the Home Road Water Plant will have the capacity to provide water to the growing Central Ohio population, which is expected to reach over 3 million by 2050. Incorporating cutting-edge, environmentally sustainable technology to efficiently provide clean, safe water, the project marks the first time a new water plant will be built for the city since the 1980s.

This site preparation project will include site clearing and bedrock removal; widening Dublin Road for dedicated turn lane access to HRWP; installation of a new 138kV Electrical Substation and other such work as may be necessary to complete the project.  

The City anticipates advertising for construction bids for the Site Preparation Contract in Summer 2024 and issuing a notice to proceed in 1st quarter 2025.

The project is not expected to have any adverse environmental impacts since construction will occur within the existing DRWP treatment basin area footprint(PDF, 631KB). The design will include provisions to address environmental issues consistent with the City’s Environmental Management System (EMS) and local, state, and federal requirements. 

The Division of Water plans to fund this project with a below market-rate loan through the Ohio EPA’s Water Supply Revolving Loan Account (WSRLA) Program. Prior to granting this loan, the Ohio EPA required a detailed submittal from the Division of Water to determine the project’s eligibility for the program.

The Ohio EPA has completed a Limited Environmental Review (LER) for this project. View the LER(PDF, 701KB) "Notice of Issuance of a Limited Environmental Review and Final Finding of No Significant Impact to All Interested Citizens, Organizations and Government Agencies.”

18. PAWP Well Pump Replacement

PAWP-Well-Pump1.jpg Summary: This project will replace nine existing raw water pumps with new vertical turbine pumps at three of the collector wells, providing a reliable raw water source to the PAWP, make use of the existing assets and maintain the current approved capacity.

This project will replace nine existing raw water pumps with new vertical turbine pumps at three of the collector wells (CW-101, 104 and115). The pumps being replaced were the original raw water pumps for the water plant constructed in early 1980's. This puts the pumps at almost 40 years old which is well beyond the typical life span of these pumps which is 15-20 years.

If no action is taken, the pumps will continue to suffer the same reduced performance and physical deterioration that was observed in the pumps removed from Collector Well 103. Replacing the pumps is the only way to continue to provide a reliable raw water source to the Plant; making use of the existing assets and maintaining  the current approved capacity.
