CIP# 690578-100000 This project at the Dublin Road Water Plant (DRWP) is a critical component in the City’s potable water supply system. The DRWP is a surface water treatment facility near Downtown Columbus (map). The purpose of this project is to modify the existing caustic soda (sodium hydroxide) storage and feed system within the DRWP and to provide caustic feed to post filtration application points. The plant can use caustic soda or soda ash for pH adjustment and targets a stable pH range of 7.8 +/_0.2 for the finished water. The project is expected to be completed in 2025. This project is part of the City’s ongoing program to upgrade its treatment facilities to provide safe, efficient, reliable, cost-effective drinking water. 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.
