Revenue model

1. Drinking Water Supply to Shareholders: WWW produces drinking water exclusively for its two 50/50 shareholders — Gelsenwasser AG and DEW21. Water is sold at bulk utility rates under long-term supply agreements. DEW21 and Gelsenwasser then distribute to end consumers in their respective territories. This is the core, essentially sole revenue stream.
2. Renewable Energy Sales: Hydropower and PV installations generate surplus electricity sold to the grid or used for self-supply, reducing operational costs.

Scale indicators9 records

Recent moves9 records

Expansion highlights5 records

Broad incumbents

• Gelsenwasser AG: Gelsenwasser is a large regional water and energy utility and holds 50% of WWW while purchasing its bulk drinking water for distribution. Its regulated water-supply and network operations make it a close operating comparator for WWW's regional production role.
• Berliner Wasserbetriebe: Berliner Wasserbetriebe is an integrated water and wastewater utility with treatment, network, and customer operations. It is a scaled incumbent benchmark for the regulated, asset-intensive operating model underlying WWW.
• HAMBURG WASSER: HAMBURG WASSER provides integrated water and wastewater services in Hamburg. Its multi-site treatment and distribution operations are relevant as a larger regulated utility benchmark for WWW.
• Stadtwerke Duisburg AG: Stadtwerke Duisburg operates local water and energy infrastructure in the Ruhr region. Its regulated municipal utility model and treatment and distribution assets are relevant comparators for WWW's asset-backed regional water supply.
• DEW21 (Dortmunder Energie- und Wasserversorgung GmbH): DEW21 is Dortmund's integrated water and energy utility, holds 50% of WWW, and distributes WWW's output to roughly 650,000 people. Its combined infrastructure, utility-regulatory, and distribution remit closely overlaps WWW's critical-infrastructure role.
• Stadtwerke Essen AG: Stadtwerke Essen provides municipal water and energy services in the Ruhr and North Rhine-Westphalia region. Its regulated, network-based utility operations offer a broader incumbent benchmark for WWW's regional critical-infrastructure business.

Regional players

• Harzwasserwerke GmbH: Harzwasserwerke operates long-distance drinking-water supply and treatment assets in Lower Saxony. Its wholesale utility-of-take model is comparable to WWW even though its service territory and raw-water system differ.
• Zweckverband Bodensee-Wasserversorgung: Bodensee-Wasserversorgung treats lake water and supplies drinking water to municipalities in Baden-Württemberg. It is a strong comparable for WWW's multi-stage treatment and wholesale utility distribution model, despite serving a different catchment.
• Fernwasserversorgung Franken: Fernwasserversorgung Franken is a wholesale drinking-water provider that supplies municipalities across Franconia. Its centralized treatment and long-distance municipal offtake closely resemble WWW's upstream bulk-water model.

Direct peers

• RWW Rheinisch-Westfälische Wasserwerksgesellschaft mbH: RWW is a Ruhr-region water utility that provides drinking-water production, treatment, and network services. Its multi-site regional water model is directly comparable to WWW's five-works, bulk-supply operations.
