Water Utility History

The Cudahy Water Utility was established in 1954 to provide safe, clean water to the residents and businesses of the city. The utility has a conventional surface water treatment plant that uses plentiful and high quality water from Lake Michigan as a water source. A conventional surface water treatment plant uses flocculation, sedimentation, filtration and disinfection to treat water. The water utility also supplies untreated lake water to two industrial customers for use in manufacturing  processes.

Water Treatment ProcessThe Cudahy Water Utility staff monitors both raw and treated water for chemical and microbiological quality. This is accomplished in many different ways. Law requires some of these tests and procedures, while others are performed for operational control. Regardless of why the test is taken, all results are used to ensure the consumer receives the finest and safest water available.
