PAWP Control Room & Laboratory

CIP# 690291-100009

The Parsons Avenue Water Plant (PAWP) is one of the three drinking water plants owned and operated by the City of Columbus. It has an approved capacity of 50 million gallons daily (MGD).

The 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 laboratory is an essential part of the plant that monitors water quality throughout the treatment process and ensures regulatory compliance.

The laboratory room does not meet functional or ergonomic needs associated with current good design practices for layout, lighting, etc. and does not leverage the advantages of modern operator interface equipment and laboratory testing. This project will reconfigure and renovate the rooms 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This project is necessary to improve space utilization, ergonomics, and to replace outdated control room and laboratory equipment. The materials are well beyond their useful life. 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 and tests that are completed in these rooms 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 City of Columbus owned property(map(PDF, 486KB)) 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 Winter of 2024/2025 and be completed by the Spring of 2026. If you have any questions concerning this project please contact the City Project Manager, Erik Schuller, P.E. in the Technical Support Section of the Division of Water (DOW) at 614-645-7100 or email:

The 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.
