Middlesex Water Co. is investing $70 million on various upgrades at its water treatment plant to provide increased resiliency and to replace sodium hypochlorite with ozone as the primary disinfectant at the Carl J. Olsen Treatment Plant in Edison.
Project partners include Northeast Remsco Construction serving as the general contractor and Jacobs Engineering Group serving as the consulting engineer. Construction is commencing and is anticipated to be completed by mid-2021.
The company says these upgrades will help ensure compliance with increasingly stringent drinking water quality regulations and to mitigate the occurrence of disinfection by-products that can form in parts of the distribution system when chlorine is used.
Ozone disinfects pathogenic organisms found in water more effectively than chlorine and is currently the most widely used water disinfection method used in the world.
