About Us
Dubuque's Eagle Point Water Facility produces an average of 6.2 MILLION GALLONS of treated water daily, with capacity to reach 18 MILLION GALLONS when needed. The current well system can pump nearly 24 MILLION GALLONS per day.
The Dubuque Water Department takes great pride in delivering high-quality municipal water that meets all state and federal quality standards. We're pleased to report that Dubuque had zero water violations in 2016. Our testing results include substances detected in our water supply, some with maximum contaminant levels established under the Safe Drinking Water Act. The EPA also requires monitoring of certain unregulated substances while they evaluate potential regulation.
For inquiries about water quality, please visit www.cityofdubuque.org/water or contact Water Department Manager Denise Ihrig, P.E., at 563-589-4291 or Water Distribution Manager Brant Schueller at 563-589-4303.
Dubuque sources water from both the Apple-Plum Alluvial aquifer and the Jordan (Cambrian-Ordovician) Aquifer. Each aquifer has different vulnerability levels based on aquifer characteristics, overlying materials, and human activities. The Apple-Plum Alluvial aquifer is considered highly vulnerable to contamination, while the Jordan aquifer has a low vulnerability rating. A detailed evaluation of our source water, completed by the Iowa Department of Natural Resources, is available at www.cityofdubuque.org/water or by calling 563-589-4291.
All water, including bottled water, may contain small amounts of contaminants. Their presence doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, call the EPA's Safe Drinking Water Hotline (1-800-426-4791).
Some individuals may be more vulnerable to water contaminants than the general population. Immunocompromised persons, including those undergoing chemotherapy, organ transplant recipients, people with HIV/AIDS, the elderly, and infants may face increased health risks. These individuals should seek advice from healthcare providers regarding safe water consumption.
Elevated lead levels can cause serious health problems, especially for pregnant women and young children. Lead in municipal water primarily comes from materials in service lines and home plumbing. While the City of Dubuque Water Department provides high-quality water, we cannot control the materials used in plumbing components. To minimize lead exposure after water has been sitting for several hours, flush your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If concerned about lead, consider having your water tested. Information on lead in water is available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.

Dubuque holds the distinction of being Iowa's oldest city and one of the earliest settlements west of the Mississippi River. The first permanent settler was French-Canadian fur trader Julien Dubuque, who arrived in 1785 when Mesquakie (Fox) Indians inhabited the area rich with lead mines. Initially secretive about their valuable lead deposits, the Mesquakie eventually shared this knowledge with Julien Dubuque as he built strong trading relationships with the tribe.
Working collaboratively with the Mesquakie to extract lead, Julien Dubuque gained control of the mines, naming them the Mines of Spain, and operated them successfully until his death in 1810. On June 1, 1833, the land was opened for settlement by the United States Government under the Black Hawk Purchase Treaty, eventually becoming chartered as the city of Dubuque in 1837.
Dubuque's strategic Mississippi River location and abundant natural resources attracted numerous immigrants, particularly Irish and German settlers escaping crowded eastern cities. Early settlers called Dubuque the "Key City"—the gateway to their dreams of prosperity. What began as a community centered on mining and fur trading evolved to include button manufacturing, boat building, logging, milling, meat packing, and various heavy industries.
Today, Dubuque serves as the primary retail, medical, education, and employment center for the tri-state region. The community takes pride in its nickname, "Gem on the Mississippi," though this wasn't always the case. During the 1980s, Dubuque faced significant challenges: double-digit unemployment, population exodus, struggling downtown businesses, and disconnected neighborhoods.
Through four community visioning initiatives over recent decades, leaders from both private and public sectors collaborated to transform downtown and stimulate industrial growth. A major challenge was reconnecting citizens to the river that inspired their city's founding—a riverfront that had become environmentally compromised and industrially dominated.
In the late 1990s, the Dubuque County Historical Society initiated the America's River project, eventually transforming 90 acres of underutilized industrial brownfield property into a vibrant waterfront destination. The area now known as the Port of Dubuque continues to develop with America's River Phase II underway, creating an impressive gateway to both the city and the state of Iowa.
