Project Description

The project included construction of a new disinfection building and plant non potable water pump station. The building is approximately 12,000 SF and houses a liquid sodium hypochlorite and liquid sodium bisulfite storage and feed system. There are 6 – 18,000 gal capacity FRP tanks for sodium hypochlorite storage and 3 – 18,000 gal capacity FRP tanks for bisulfite storage. It includes a new pump station to provide non potable water for the entire MWRD treatment plant. The pump station includes a new wetwell, 4 new vertical turbine pumps, surge protection and mechanical screening capability. The project also includes a significant amount of new from 2” to 48” yard piping to connect the new piping systems to existing yard piping systems. This involves extensive uncovering and protection of existing systems to ensure the existing plant maintains continuous operation throughout construction.
