Revenue model

1. Water Supply to Member Municipalities: SES sells drinking water to its 22 member municipalities at regulated tariff rates. The 2010 price was 1.00€/m³ for member communes. Member municipalities then distribute water to households and handle local billing.
2. Water Supply to Industrial Customers: SES directly supplies drinking water to industrial sites including Arcelor Mittal steel plants at Esch-Belval, Esch-Schifflange, and Differdange, as well as other industrial sites. Industrial pricing was 1.25€/m³ in 2010.
3. Water Supply to Non-Member Localities: SES provides direct drinking water supply to certain localities not affiliated with the syndicate, including direct supply to Bertrange and several other non-member municipalities.

Scale indicators7 records

Recent moves3 records

Regional players

• SIDERO (Syndicat Intercommunal de Distribution d'Eau de la Région de Roedgen): Another Luxembourg intercommunal water syndicate operating in a different region of the country. Comparable structure, regulatory framework, and customer base (member municipalities), but geographically distinct.
• Société Wallonne des Eaux: Walloon regional water operator (Belgium) providing drinking water distribution services. Comparable public utility structure and regulated multi-municipal service model, serving the neighboring Belgian region.

Direct peers

• Wiener Wasser (Stadt Wien - Wasserwerke): Vienna's municipal water utility operating protected alpine spring sources (1st and 2nd Vienna Mountain Spring Pipeline) with ultra-high water quality standards and pipe-marking services. Comparable high-quality municipal water operation.
• Eau de Paris: Municipal water utility serving Paris and surrounding communes — a comparable public drinking water operator with extensive pipeline network, groundwater sources, and intercommunal/municipal governance. Directly analogous operating model in a different geography.
• DEA - Distribution d'Eau des Ardennes: Luxembourg intercommunal water utility historically sharing a joint management agreement with SES (1987-1992). Operates in a complementary region of Luxembourg and represents the most direct structural and operational peer.
• Berliner Wasserbetriebe: Berlin's municipal water utility, publicly owned and serving millions of residents with surface and groundwater sources. Comparable public utility model with similar treatment (membrane filtration) and infrastructure scope.
• SEBES (Syndicat des Eaux du Barrage d'Esch-sur-Sûre): Luxembourg intercommunal water syndicate operating the Esch-sur-Sûre dam that supplies surface water to SES and other Luxembourg utilities. Direct infrastructure partner and supply peer in the same Luxembourg water ecosystem.

Broad incumbents

• Severn Trent plc: Large publicly listed UK water utility providing regulated water and wastewater services to millions of customers. Represents the listed-equity utility comparable, although at vastly larger scale and with wastewater scope SES does not have.
• Veolia Eau Luxembourg / Veolia Water Technologies: Global water utility and services provider operating in Luxembourg. Provides municipal water services and treatment technologies; while not a direct structural peer, it represents the broader incumbent competition in European municipal water.

Others

• Aqua for IT / Veolia Eau (France): Provider of IT and operational technology solutions to water utilities, including GIS and asset management systems analogous to those used by SES. An enabling technology peer rather than a direct utility competitor.
