West Dayton Street Sanitary Sewer Replacement
August 25, 2025 Update
Survey of the project area has been obtained by City staff and the design of the new sewer along W. Dayton St is nearly complete. We are now verifying with private utilities and UW-Madison that the design is suitable given their facilities in the area. The project is still slated to be bid at the end of September with construction slated for next Spring/Summer (2026).

Project Information
Project Overview
The existing sanitary sewer mains will be replaced and upsized on West Dayton Street between North Lake Street & North Frances Street. The existing sanitary sewer is 18” clay and was installed in 1931. The new sewer will be 24” PVC. Within these replacement limits, existing sanitary sewer laterals will be reconnected into the new sanitary sewer main(s). However, it is expected that all connected existing sanitary sewer laterals are made of PVC and in such condition that replacement of existing laterals is not necessary.
The City will coordinate this work with nearby UW-Madison facilities such that impacts to traffic, UW-events, etc. are minimized by this project.
