Clean Beach Treatment Systems

A map of the Clean Beach Treatment SystemThe Dane County Clean Beach Treatment Systems (PDF) use a flexible curtain and chemical-free water treatment process to create a safe swimming area with clear, beautiful, algae-free water. This helps minimizes beach closings due to algae and E. coli.

These treatment systems allow visitors to enjoy the lakes right now, as Dane County and other partners work to improve the water quality of the Yahara chain of lakes through long-term projects.
