Dear Chicago Water Customer,
This Water Quality Report meets a formal obligation to report to every customer on the drinking water we purify and deliver. I am pleased to report our water is safe and meets or exceeds every standard established by the US Environmental Protection Agency and the Illinois Environmental Protection Agency.
This report, of course, does not tell the full story of our water system. We face challenges of infrastructure renewal. More than a quarter of our 4,300 miles of water main are beyond their one hundred year life expectancies. It is imperative that we renew our system and we have launched an ambitious program to triple the rate of main replacement. This is essential to have a system that efficiently and safely serves our city and suburban customers. In the next ten years, we will replace 880 miles of water mains, and lining or replacing over 700 miles of sewers, all of which are 100 years old or more. We can take pride in the water we have and both the system
that produces it. There is much to be done, and I look forward to working together to improve and protect this valuable resource.
