Construction for this project is complete.
Project Overview
The Flow Splitter structure is located within the Nine Springs Wastewater Treatment Plant. This structure receives the entire plant’s flow after screening and grit removal in Headworks. It was constructed in 2006 as part of the District’s 10th addition.
The purpose of the project is to rehabilitate the Flow Splitter infrastructure and provide a means of bypassing the structure in case of future shutdowns. Over the past 20 years, high gas levels trapped within the structure have corroded the interior concrete walls. A new bypass channel will be constructed, and the interior walls and equipment will be repaired and replaced.
The structure rehabilitation work will be confined within the Nine Spring Wastewater Treatment Plant with minimal impacts to the surrounding area.
Public Involvement
Due to the nature of the project, no public information meetings are required for this project.
Project Funding
Construction of upgrades and improvements to the District Flow Splitter Improvements project were financed by the Clean Water State Revolving Fund. The CWSRF program is administered by WI DNR with joint funding from the U.S. Environmental Protection Agency and State of Wisconsin. This project benefits community residents and businesses in and near the City of Madison as well as providing water quality benefits for the larger Madison Metropolitan Sewerage District service area and downstream watersheds. CWSRF programs operate around the country to provide states and communities the resources necessary to maintain and improve the infrastructure that protects our valuable water resources nationwide.
