Key Terms

lead service lines, pfas, pfos, wastewater clarifier, +1 more

5 terms

lead service lines technical

"Replacing lead service lines for both the company- and customer-owned portions"

Lead service lines are the water pipes that connect a public water main to an individual building and are made wholly or partly of lead. They matter to investors because the presence of these pipes creates a public-health liability and can trigger large replacement costs, regulatory penalties, or reduced property values—much like an aging electrical system that must be replaced to avoid safety risks and legal exposure.

pfas medical

"Enhanced water treatment including projects addressing PFAS"

PFAS are a group of human-made chemicals used in many everyday products, such as non-stick cookware, water-repellent clothing, and food packaging, because they resist heat, water, and grease. They are often called "forever chemicals" because they do not break down easily in the environment or the human body, potentially leading to health concerns. For investors, the presence of PFAS-related risks can impact companies’ reputations, legal liabilities, and future costs.

pfos medical

"$6.5 million in PFOS water treatment plant improvements in Lincoln"

PFOS (perfluorooctane sulfonate) is a long-lasting industrial chemical once used for water-, stain- and grease-repellent coatings and firefighting foams; it does not break down easily in the environment or the body. Investors care because PFOS can trigger strict regulations, cleanup obligations, product bans and lawsuits that create large, sometimes unexpected costs and reputational damage for companies in affected industries—similar to finding a hidden, persistent leak that requires expensive repairs and legal bills.

wastewater clarifier technical

"$6 million in a Wastewater Clarifier replacement in Granite City"

A wastewater clarifier is a large tank or vessel that separates solid particles from water by letting the solids settle to the bottom while clearer water flows out, much like letting coffee grounds sink in a cup before pouring. For investors, clarifiers matter because they are essential to meeting environmental rules, controlling cleanup and operating costs, and can affect a company’s regulatory risk, capital spending and the value of water-treatment businesses or industrial facilities that rely on them.

lift station technical

"$2.5 million in Lift Station improvements in Homer Glen"

A lift station is a pump facility that moves sewage or stormwater from lower to higher ground when gravity pipes alone can't carry it, like a booster pump on a hill for a drainage system. Investors care because these stations are essential public-utility assets that require regular maintenance, upgrades, and regulatory compliance; their condition and funding affect operating costs, capital spending needs, service reliability, and potential liabilities for municipalities and utility companies.

Illinois American Water plans to invest approximately $570 million through 2027 focused on upgrading aging infrastructure, enhancing water quality, reducing service disruptions, and improving system resilience.

"Infrastructure Week is an opportunity to highlight the essential role water and wastewater systems play in our communities," said Rebecca Losli, President of Illinois American Water.

• Technology and operational efficiency upgrades including automation, leak detection, and system monitoring

Losli added, "As we look to the future, investments in infrastructure remain a top priority to help ensure we can continue providing high-quality water and wastewater services for customers now and for generations to come."

Planned and ongoing projects span communities throughout the state and include some of the following examples:

• $25 million in the Lead Service Line Replacement Program across Illinois, continuing efforts to replace aging service lines and improve water quality. Since 2020, over 5,200 lead or qualifying galvanized steel service lines have been replaced
• $15.5 million in Water Treatment Plant improvements in Sterling to enhance reliability and optimize treatment processes
• $6.5 million in PFOS water treatment plant improvements in Lincoln to enhance water quality and meet regulatory requirements
• $6 million in a Wastewater Clarifier replacement in Granite City to modernize aging infrastructure and improve system performance
• $3.5 million in a Booster Tank installation in Woodridge to increase storage capacity and improve redundancy
• $2.5 million in Lift Station improvements in Homer Glen to modernize aging infrastructure and improve the reliability of the wastewater system
• $1 million in Water Storage Tank renovations in Bolingbrook to improve resiliency and prevent corrosion

In addition to modernizing critical systems that often operate out of sight but are essential to daily life, ongoing infrastructure investment supports local economies. Studies have shown that for every $1 million invested in water infrastructure, 10 jobs are created. The work is completed by highly skilled union employees.
