Water. H2O. Most of us in northeastern Illinois don’t pay much attention to our drinking water. We mindlessly turn on faucets dozens of times a day without pausing to consider questions that millions of people around the world worry about on a regular basis: Do we have enough? Is it clean? Will it endure?
We are lucky: In northeastern Illinois, we generally enjoy an ample amount of water thanks to our location along the shores of a Great Lake. But that good fortune has lulled us into complacency, and our drinking water systems have been neglected. Our proverbial glass is half empty.
This is the Metropolitan Planning Council’s bid to raise awareness, and our call to action on addressing water supply issues in our region. We are ready to form stronger partnerships with elected officials, utility managers and operators, funders, private organizations, nonprofits and others to advance a 10-point action agenda by 2021.
What’s at stake? Public health and safety risks, including contamination due to 100-year-old pipes and aging water treatment systems. Local and regional resiliency during times of crisis. New jobs and regional economic growth, since every company needs water—and some more than others. Vital ecosystems. Municipalities and their residents hard-pressed to afford the escalating costs to collect, treat and deliver drinking water. And, yes, some communities running out of water within 15 years.
The Metropolitan Planning Council is dedicated to ensuring a resilient, thriving, equitable and healthy region. While our water supply issues are significant, they are fixable. We invite you to join us in implementing this 10-point action agenda, to ensure our region’s glass remains full.
The top three drinking water issues we face as a region are encapsulated in the following three questions: Do we have enough? Is it clean? Will the system endure? The answer to all three questions will be a stark “no” if we do not take coordinated action.
What’s more, the system of infrastructure, institutions and regulations that bring water from the lake, rivers and underground aquifers to your tap is complicated and fragmented. Consumers are buffered from these complexities, and therefore are disconnected from understanding why we need to invest in this critical service that enables us to drink, bathe and indeed survive. Read on to learn why collective action now—versus when a crisis hits—is imperative.
Fragmented system, disconnected users
Did you know more than 400 community water supply systems operate in northeastern Illinois? Yes—over 400—and each individual utility produces or purchases drinking water, and distributes it through a system of pipes and pumps they maintain. Most of these utilities are owned and managed by a municipality, which means decisions about water utility operations, infrastructure investment, future planning and service rates are made at the local level by elected officials who may or may not have prior expertise in managing a water utility.
To further exacerbate this complexity, northeastern Illinois does not have a well-followed system for regularly tracking water usage from each utility. As a result, we lack a big picture understanding of current regional demand for drinking water. While communities that use Lake Michigan water must report usage and infrastructure conditions, the rest of the region—particularly those communities who are facing water shortages—are not held to the same standard. Because of these factors, our region is extremely fragmented in our approach to managing a vital resource, which by its very nature is regional and shared. We need more coordinated, regional water supply planning.
Another fundamental challenge is that we as consumers are very disconnected from the complex system that provides us with water to drink, bathe and survive. Consider this: Do you know where your water is treated? Do you know your water rate? Have you ever tracked how much water you used in one day? Most people in our region would answer “no” to these questions.
Our region’s collective lack of awareness about our drinking water may stem from historically ample supplies of water, the buried nature of water infrastructure, and the low, subsidized costs we have enjoyed for water service. We haven’t needed to give a second thought to the infrastructure and operations it takes to deliver water to our homes and businesses, so we make perplexing and wasteful decisions, such as treating water to drinkable standards and then using it to water lawns or support industrial processes such as heating and cooling.
Conditions related to our drinking water have changed. Our region faces near-term water supply constraints, pollution and crumbling infrastructure. How we answer the following three questions in 10 years depends entirely on our collective actions today.
Do we have enough?
The Ill. State Water Survey, which has been monitoring and modeling Illinois’ water resources for more than a century, released a seminal report in fall 2015 about the water levels in wells throughout northern Illinois. The report sounded an alarm about how much groundwater we really have:
- Our deep sandstone aquifers are being depleted unsustainably.
- High-capacity wells could be unusable in as little as 15 years.
- Many more wells could be dry by 2050.
If current practices continue, some community and industrial wells could be unusable within 15 years, and even more will be at risk by 2050.
Why does this matter? About 31 percent of northeastern Illinois’ population—including outer ring suburbs of Chicago—rely on water sources other than Lake Michigan. About 17% of them rely solely on groundwater, and to serve them, some 90 million gallons per day are being withdrawn from the deep sandstone aquifers—a withdrawal rate at least twice as high as the Ill. State Water Survey estimates to be sustainable for future use of these sources. Some areas are already experiencing significant depletion and some shallower, private wells are already going dry. If current practices continue, some community and industrial wells could be unusable within 15 years, and even more will be at risk by 2050.

Some might think the easy answer to this issue is for more communities to tap into Lake Michigan. However, Illinois’ allotted diversion of Lake Michigan water is limited by a U.S. Supreme Court decree. So while we may think our region enjoys an unlimited amount of fresh water, that is not true.
This growing issue could negatively affect the regional economy, costing local communities jobs if businesses relocate due to water shortage concerns. We can prevent this if current groundwater users in our region—including municipalities, self-supplied commercial and industrial facilities and irrigators—plan and work together. Best practices in water reporting, plumbing codes, demand management and water reuse must become well known and widely adopted.
Is it clean?
Northeastern Illinois’ water supply faces increasing pollution from a variety of sources, including:
- chlorides from salting our roads and sidewalks;
- fertilizers from lawns and agriculture;
- organic (human waste) and inorganic matter (such as pharmaceuticals) from sewer overflows;
- lead from old or faulty fixtures or pipes; and
- toxins from industrial processes
Maximum Contaminant Levels (MCLs) are standards set by the United States Environmental Protection Agency (EPA) for drinking water quality. An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act.
Clean water is obviously critical to our health and well-being. It is also important to note that increases in water pollution in our local water sources—lakes, rivers and underground aquifers—ultimately raise the cost of providing drinking water. The more pollution we have in our drinking water sources, the higher our water rates will be in the future, because additional filtration and treatment processes are required to ensure that water is safe for human consumption.
Increasingly, water pollution is an issue in northeastern Illinois. Just one example: In March 2016, the Illinois State Water Survey released a report on the shallow groundwater quality in Kane County. The greatest concern is chloride levels: Two-thirds of water samples taken from eastern Kane County between 2003 and 2015 had chloride concentrations above the secondary maximum contaminant level. Road salt is one of the most likely sources of this contamination. The unfortunate results may be increased water treatment costs, as well as corrosion of pipes in homes and industrial plants, as chloride is highly caustic.
What can we do to reduce pollution? We can embrace best management practices such as sensible salting, which will help reduce the amount of chlorides in our water sources; reduce nitrogen and phosphorus pollution in our water by supporting the Ill. Environmental Protection Agency’s Nutrient Loss Reduction Strategy; and upgrade our stormwater infrastructure to reduce sewer overflows into our water sources.
Will the system endure?

In 2008, this stretch of Montrose Avenue on Chicago's North Side collapsed due to a water main break.
Much of northeastern Illinois’ water infrastructure—think treatment plants, pumps and pipes—built to collect, treat and deliver drinking water to our homes and businesses 24 hours a day, seven days a week, is coming to the end of its useful life. Plainly put, the infrastructure is old—anywhere from 50 to 100 years old—and in dire need of repair and replacement to ensure safe and reliable service to your home and business in the future. It is fact, not hyperbole, to say that if we fail to act, we face catastrophes such as water main breaks, collapsing infrastructure and drinking water contamination.
What’s more, our pipe network is buried out-of-sight, so it is also out-of-mind for most of us, contributing to our disconnect from what it takes to maintain it. Practically speaking, it’s also challenging to know the condition of buried pipes—but we know it’s not a pretty picture: Best-guess estimates suggest we lose 26 billion gallons each year due to deteriorating infrastructure—enough water to fill more than one Willis Tower every week. Without a clear understanding of our water infrastructure conditions, we’ll continue to see utilities across northeastern Illinois spend money on drinking water that never even gets to consumers.
Addressing our aging water infrastructure in Illinois is estimated to cost around $21.5 billion through 2030. Our local water utilities need viable funding and financing streams in order to make this huge investment. We need to explore economies of scale and service sharing between utilities. At the same time, equitable water rate practices need to be employed to ensure everyone in our communities has access to clean drinking water. Now more than ever, industry standards in auditing and reporting the condition of our systems, establishing robust asset management programs and identifying investment needs are imperative.
Most people in northeastern Illinois have no idea that water supply issues lurk just below the surface. They trust that work is being done to protect and manage this incredible resource, and to head off crisis before it happens.
To live up to that expectation, we need to address a number of issues today, not in the future when a crisis hits and the costs are even greater. It will take a team effort, but by collaborating regionally and acting locally and boldly, we can advance bite-size solutions to these issues.
