Dunea

What Dunea does

Dunea N.V. is a Dutch non-profit regional drinking water utility incorporated as an N.V. (public limited company) under public-law ownership, headquartered in Zoetermeer and supplying drinking water to approximately 1.3 million people across the South Holland Randstad. The company's core technology is a dune-infiltration system: pre-treated river water from the Afgedamde Maas is piped to infiltration ponds in the 2,500-hectare dune area between Monster and Katwijk (Solleveld, Meijendel and Berkheide), where it is naturally filtered through sand and dunes before final purification and distribution. Dunea reports one of the best supply-continuity records in the world, with average interruption of 20 minutes per connection per year (4 minutes unplanned), and operates an integrated ecosystem combining drinking-water supply with biodiversity protection of the dune reserves, public recreation (excursions, De Tapuit visitor centre, Solleveld and Kijfhoek & Bierlap day passes) and primary-school education (Duincampus, Expeditie Zuivergoed, Gastles Kraanwater).

The revenue model is anchored in regulator-published, usage-based water tariffs (€1.45/m³ in 2026, €1.34/m³ in 2025, excluding 9% VAT) plus a tiered vastrecht fixed standing charge (€90.41/year for 1,500 l/h connections in 2026) and a one-time connection fee of €1,708 for standard capacities. The statutory Belasting op Leidingwater (Tap Water Tax) of €0.437/m³ in 2026 is collected on the first 50,000 m³ per connection per year, with the threshold removed from 2027. Customer mix is dominated by residential accounts (96% on 1,500 l/h meters; 3% on 2,500+ l/h; ~1% industrial up to 250,000 l/h), served through the Mijn Dunea self-service portal, mijnaansluiting.nl for new connections, and direct enterprise account management for commercial, fire-sprinkler and high-volume industrial supply. Supplementary revenue streams include Evenementenwater tap-unit rentals (€300/placement), themed and group excursions in Nationaal Park Hollandse Duinen, day tickets for sensitive dune areas, and a commercial aquathermie installation at Mall of the Netherlands providing 1.5 MW of sustainable cooling since 2020.

The business is structured as a designated regional monopoly under the Drinkwaterwet, with ownership held by Dutch public-law shareholders and governance through a shareholders meeting and a Raad van Commissarissen (a new member, Annetje Ottow, was appointed in June 2026). Dunea is updating its Water Act permits with the Province of South Holland and Omgevingsdienst Haaglanden to accommodate ~200,000 additional regional customers and climate-driven salinisation, while pursuing adjacent innovations including a brak-groundwater desalination pilot, Wetsus research membership on desalination and nanotechnology, and Greenport Westland-Oostland collaboration on water reuse and energy in greenhouse horticulture. International development cooperation is conducted through Dunea Internationaal in Mozambique and Kenya.

Broad incumbents

• Severn Trent: Listed UK water and wastewater utility regulated by Ofwat, serving ~4.5 million households in the Midlands and Wales. Comparable as a large regulated water utility with a public-interest mandate, growing focus on sustainability-linked adjacent services and published reliability/CSL metrics similar to Dunea's interruption claims.
• Veolia Eau (Veolia Water Technologies / Sidem): Global environmental services group operating municipal water concessions across multiple continents. Broad incumbent comparable on regulated water production, distribution network operations and increasingly on thermal-energy-from-water solutions analogous to Dunea's aquathermie.
• Suez (Suez Eau France): Global water and waste management group with municipal water utility concessions across Europe, including France and international markets. Broad incumbent comparable on regulated water utility operations, smart metering rollouts and large-scale customer service platforms.

Direct peers

• Vitens: Largest Dutch drinking water utility, serving ~5.7 million people across Friesland, Overijssel, Gelderland, Utrecht, Flevoland and Noord-Holland. Comparable as a regulated Dutch drinking water monopoly operating under the same Drinkwaterwet framework and tariff regulation, with similar nature-area management and innovation agendas.
• Brabant Water: Drinking water utility for the province of North Brabant. Comparable Dutch regulated water monopoly with similar customer-base characteristics (predominantly residential, small industrial tail) and the same statutory obligations under the Drinkwaterwet.
• Oasen: Smaller Dutch drinking water utility serving the Gouda, Alphen aan den Rijn and surrounding areas in South Holland and Utrecht. Comparable as a regional Dutch water monopoly with surface-water-based production and similar regulatory exposure.
• Evides: Drinking water utility serving parts of South Holland (including Rotterdam area), Zeeland and North Brabant. Direct comparable as a Dutch regulated drinking water monopoly operating adjacent supply areas to Dunea under the same Drinkwaterwet regime.
• PWN (Publieke Waterleidingmaatschappij van Noord-Holland): Dutch drinking water utility supplying the North Holland province, including dune-based water production from the Kennemerduinen. Closely comparable to Dunea in that both use dune infiltration systems, manage large nature reserves and operate as public-law drinking water monopolies.
• Waternet: Water utility owned by the City of Amsterdam and the Amstel, Gooi en Vecht water authority, responsible for drinking water, wastewater and waterways in the Amsterdam region. Comparable as a municipal/public-law owned Dutch water utility with both drinking-water and broader water-chain responsibilities.
• Waterschapsbedrijf Limburg (WBL): Water authority company for the province of Limburg, handling wastewater treatment and increasingly involved in drinking-water-related water-chain activities. Comparable as a public-law Dutch water entity operating under similar regulatory oversight.
