Where the water comes from

Watseka draws water from 3 wells. 1 other community water system and 2 smaller public systems such as schools, businesses or campgrounds buy water from Watseka.

Community systems that buy water from it

Annual water quality report

Watseka must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
