PAWP Control Room Renovation


The Parsons Avenue Water Plant (PAWP) is one of the three drinking water plants owned and operated by the City of Columbus (CoC). It has an approved capacity of 50 MGD. The PAWP control room is the primary location where plant staff monitor and control the treatment process. The room houses operator workstations, computer hardware, networking equipment, and electrical equipment related to the plant’s Supervisory Control and Data Acquisition (SCADA) system. The room does not meet functional or ergonomic needs associated with current good design practices for control room layout, lighting, etc. and does not leverage the advantages of modern operator interface equipment.

This project will reconfigure and renovate the control room to meet functional and ergonomic needs, provide improved lighting, etc.  

This project is necessary to improve space utilization, ergonomics, and to replace outdated control room equipment and materials that are well beyond their useful life expectancy. The control room SCADA and instrumentation & control equipment are essential to the water treatment process with a limited number of operators on duty. The instrumentation and controls housed in this room are vital to the treatment and supply of safe drinking water to the Columbus and the Central Ohio area. 

All improvements will be made within CoC owned property and is not expected to have any adverse environmental impacts. The design will include provisions to address consistent with the City’s Environmental Management System (EMS) and local, state and federal requirements.

Work is scheduled to commence in the Summer of 2023 and be completed by the Summer of 2024.

The Division of Water (DOW) 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 requires a detailed submittal for the Division of Water to determine the project’s eligibility for the program.
