Milwaukee’s tap water begins its journey in Lake Michigan, which supplies fresh water to nearly 1 million people across Milwaukee. The Milwaukee Water Works (MWW) uses a multistep process that includes ozonation, sedimentation, filtration and disinfection to treat this raw lake water. The system is one of the most rigorously monitored in the United States, with testing for over 500 potential contaminants to meet and exceed all existing standards.

While municipal treatment tackles safety, how it tastes, smells and flows through your office depends heavily on what happens after it leaves the plant. For businesses focused on creating a positive workplace and minimizing single-use plastic, Culligan Quench’s bottleless water coolers are a dependable alternative.

Milwaukee tap water is safe. It’s sourced from Lake Michigan and treated with care through a multistage purification process. The MWW has a reputation for safety, routinely publishing its Consumer Confidence Report and staying transparent about water quality performance.

If your workplace is inside a building constructed before 1951, there’s one key issue to consider: lead service lines. While the city’s water leaves the treatment plant lead-free, it can absorb trace amounts if it passes through outdated pipes on the way to your faucet.

For office managers or facilities professionals who want to skip the uncertainty, a point-of-use filtration system is a practical safeguard. Many organizations use our sparkling water dispensers and ice machines to round out a full hydration station that supports employee well-being and meets today’s expectations for environmental care.
