Stadtwerke Düsseldorf: 160 Years of Reliable Drinking Water Supply
On August 28, 2026, Stadtwerke Düsseldorf transformed the Uecker-Nagel installation near Kö-Bogen into a hub of public education and relaxation. The H2Oase pop-up event brought municipal utility outreach directly to the downtown area.
Coping With Summer Demand Spikes
Urban heatwaves place intense pressure on municipal utility networks. Daily water consumption spikes from a baseline average of 150 million liters up to 200 million liters on hot summer days.
Municipal systems must balance this soaring demand with strict regulatory compliance.
Engaging the Public at Uecker-Nagel
The H2Oase initiative ran from 13:00 to 19:00 on Friday, August 28, 2026, according to reports from Stadtwerke Düsseldorf and Lokalbuero. Visitors at the landmark enjoyed cooled tap water, fruit-infused water cocktails, ice cream refreshments, and background music provided by a live DJ.
Family-friendly activities included face painting and bubble stations. Meanwhile, utility experts maintained an informational booth to discuss water origins, quality, and treatment methods with the public.
Rhine Bank Filtration and Deep Groundwater
Operating continuously for more than 160 years, Stadtwerke Düsseldorf utilizes a distinct sourcing model to maintain supply stability. Data from the utility shows that approximately 75 percent of the region’s drinking water originates from Rhine bank filtration. The remaining 25 percent comes from groundwater reserves.
The filtration process relies on river water percolating through the riverbed and traveling via underground passages to the facility extraction wells. Because the extraction pumps sit at significant depths within the production wells, fluctuating river levels do not disrupt raw water availability during seasonal droughts.
The 20 Million Euro Gerresheim Reservoir Project
To future-proof the regional network against growing populations and extreme weather, utility leadership is deploying capital into extensive modernization programs. Stadtwerke Düsseldorf is currently constructing a new drinking water storage reservoir in the Gerresheim forest area with a total budget of 20 million euros.

This modern facility will replace a predecessor that is more than 100 years old. It will work alongside existing high-level storage tanks to safeguard the municipal supply for approximately 800,000 residents across Düsseldorf, Mettmann, and Erkrath.
Mindful Consumption and Future Infrastructure
Despite robust infrastructure and an uninterrupted operational record free of supply restrictions, municipal representatives consistently advise residents to practice mindful water consumption regardless of prevailing weather conditions.
