Chlorine Contact Basin Drain Valve Replacements at the South Shore Water Reclamation Facility

This project involves the replacement of six 10-inch drain valves located at the Chlorine Contact Basins of the South Shore Water Reclamation Facility. These valves are situated approximately 22 feet underground and are connected to cement-lined ductile iron piping. The scope of work includes developing a detailed excavation and backfill plan, which must be certified by a Wisconsin-registered Professional Engineer, as well as performing excavation, installing temporary plugs or line stops, and removing and reinstalling the 8-inch underdrain. The contractor will supply and install new spool pieces and modify associated piping, conduct leak testing, and restore the site with topsoil and turf grass. Additionally, the project entails removing existing drain line plugs within the North Basin. The contract, issued by the Milwaukee Metropolitan Sewerage District, is valued between $500,000 and $1,000,000 and is open for responses until June 12, 2024. The work is to be performed in Wisconsin and requires coordination with the district’s designated contact, Millie Neidhardt. The project emphasizes careful planning and execution of underground piping modifications, ensuring system integrity through testing, and restoring the site to its original condition following completion.
