What Hoogheemraadschap De Stichtse Rijnlanden does

Hoogheemraadschap De Stichtse Rijnlanden (HDSR) is a Dutch statutory water management board (waterschap) — an independent public administrative body under Dutch law — responsible for water safety, water quality, and sufficient water quantity across the province of Utrecht and a portion of South Holland. The organization manages critical water infrastructure including 55 kilometers of dike reinforcement along the Sterke Lekdijk, the Klimaatbestendige Wateraanvoer (KWA) climate-resilient water supply system with up to 18 m³/s capacity to combat drought and saltwater intrusion in West-Netherlands, locks (Sluis Bodegraven), pumping stations (gemaal De Aanvoerder, Noordergemaal Utrecht), and the Leidsche Rijn wastewater treatment plant equipped with a fine-screen installation for resource recovery. Operational programs include three-times-yearly dijkschouw dike inspections, depth/profile inspections of tertiary waterways, autumn najaarsschouw, water quality monitoring at 27 official swimming locations, and the Utrechtse Visdeurbel fish migration camera.

HDSR delivers its services through digital citizen portals authenticated via DigiD, eHerkenning, and eIDAS, supported by a physical office at Poldermolen 2 in Houten, a 24/7 emergency hotline, and public board meetings. Service standards include email responses within 3 working days, complaints acknowledged within 5 working days, and damage reports handled within 10 working days (24 hours for urgent cases).

The organization is funded through waterschapsbelasting (water board taxes) levied on property owners within its jurisdiction — no commercial pricing model applies. It collaborates with Rijkswaterstaat, Hoogheemraadschap van Rijnland, Hoogheemraadschap Schieland en Krimpenerwaard, Waterschap Amstel Gooi en Vecht, Provincie Utrecht, Provincie Zuid-Holland, Vitens, and municipalities on drought management, flood protection, wastewater treatment consolidation, and climate adaptation. The next water board elections are scheduled for March 17, 2027.

Partnerships

Eight partnerships are on record, tiered core and secondary.

• Hoogheemraadschap van RijnlandcoreStrategic or Co-development Partner · 30 June 2026Collaborative partnership on the Klimaatbestendige Wateraanvoer (KWA) system. Both water boards jointly activated the KWA on June 30, 2026, to combat drought and salt intrusion in West-Netherlands. Rijnland and HDSR share responsibility for distributing fresh water through their regional water systems. KWA can supply up to 15 m³/s of fresh water to the Rijnland region.
• Rijkswaterstaat (Ministry of Infrastructure and Water Management)coreStrategic or Co-development Partner · 30 June 2026Central government water management authority collaborating with HDSR and other water boards on the KWA system. Rijkswaterstaat manages the main water system (hoofdwatersysteem) and makes water available for distribution. Rijkswaterstaat Director Rachid Bassit confirmed the partnership emphasizing the importance of water board cooperation. HDSR hoogheemraad Bert de Groot noted that 21 water boards collaborate with Rijkswaterstaat.
• Hoogheemraadschap Schieland en KrimpenerwaardsecondaryStrategic or Co-development Partner · 30 June 2026Partner in drought management via the Doorvoer Krimpenerwaard (DKW) route. Schieland en Krimpenerwaard supplies water from the Lek via gemaal Verdoold to the Hollandsche IJssel, contributing an additional 3 m³/s of fresh water to West-Netherlands during drought conditions.
• Waterschap Amstel, Gooi en VechtsecondaryStrategic or Co-development Partner · 4 January 2021Collaboration to consolidate wastewater treatment operations. Waterschap Amstel, Gooi en Vecht redirects wastewater from Maarssen to the Leidsche Rijn wastewater treatment facility operated by HDSR via a press pipe under the A2 motorway. This merged three wastewater treatment plants (Maarssen, Maarssenbroek, and Maarssen from Amstel, Gooi en Vecht) into one efficient facility.
• Provincie UtrechtsecondaryStrategic or Co-development PartnerProvincial authority collaborating with HDSR on drought management, water quality, groundwater protection, and climate adaptation. HDSR participates in the Drinkwaterraad (Drinking Water Council) together with the province, municipalities, and water boards to address the projected drinking water shortage from 2032 onward.
• Provincie Zuid-HollandsecondaryStrategic or Co-development PartnerProvincial authority in the southern part of HDSR's jurisdiction, collaborating on drought management and water governance. HDSR manages water systems in a portion of Zuid-Holland province.
• Vitens (Drinkwaterbedrijf)secondaryStrategic or Co-development PartnerLargest drinking water company in the Netherlands collaborating with HDSR on groundwater protection and drinking water supply planning. Both organizations are members of the Drinkwaterraad addressing the projected drinking water shortage in the Utrecht region from 2032.
• Gemeenten in HDSR-gebied (Municipalities)secondaryStrategic or Co-development PartnerHDSR collaborates with municipalities within its jurisdiction on spatial planning, climate adaptation, green infrastructure (tegels eruit, groen erin), and rainwater disconnection (regenpijp afkoppelen).

Direct peers

• Hoogheemraadschap van Rijnland: Dutch water board responsible for water management in the western South Holland region. Direct peer and KWA joint-activator with HDSR; both share statutory water management mandates, KWA infrastructure operations, and freshwater distribution responsibility for the Randstad.
• Hoogheemraadschap Schieland en Krimpenerwaard: Dutch water board governing water management in the Krimpenerwaard and Schieland regions. Direct peer operating the DKW route that adds 3 m³/s to the KWA freshwater supply to West-Netherlands, with overlapping dike and waterway maintenance mandates.
• Waterschap Amstel, Gooi en Vecht: Dutch water board covering Amsterdam and surrounding areas. Direct peer that consolidated three WWTPs with HDSR via the 2021 wastewater collaboration, sharing statutory water management duties and wastewater treatment operations in the Randstad.
• Hoogheemraadschap van Delfland: Dutch water board serving the Delfland region including western South Holland. Direct peer with similar statutory water management mandate, dike maintenance programs, and water quality monitoring responsibilities in a comparable urbanized delta region.
• Waterschap Rivierenland: Dutch water board covering the Betuwe, Gelderse Vallei, and Rivierenland areas. Direct peer with overlapping dike reinforcement programs (along major rivers like the Waal), drought management, and waterway maintenance responsibilities.
• Hoogheemraadschap Hollands Noorderkwartier: Dutch water board for North Holland north of the IJ and the West Frisian polders. Direct peer handling comparable dike management, water level control, and wastewater treatment in a low-lying Dutch delta region.
• Waterschap Zuiderzeeland: Dutch water board managing Flevoland polders and surrounding waters. Direct peer with statutory mandate for water level control, dike maintenance, and water quality in a fully engineered polder landscape.

Broad incumbents

• Rijkswaterstaat: National water and transport authority under the Ministry of Infrastructure. Broader incumbent operating the main water system (hoofdwatersysteem) that supplies the KWA; HDSR distributes what Rijkswaterstaat makes available, making them complementary rather than directly competing.

Regional players

• Vitens: Largest drinking water company in the Netherlands. Adjacent player collaborating with HDSR on groundwater protection and the Drinkwaterraad; operates downstream of HDSR's water management, sourcing drinking water from the same aquifers HDSR protects.

Others

• Provincie Utrecht: Provincial authority governing Utrecht province. Partner (not peer) collaborating on drought management, water quality, groundwater protection, and the Drinkwaterraad — sits in HDSR's governance ecosystem rather than competing with its water management mandate.
