What Hoogheemraadschap van Schieland en de Krimpenerwaard does

Hoogheemraadschap van Schieland en de Krimpenerwaard (HHSK) is a Dutch water management board (waterschap) — a statutory public-law entity responsible for flood protection, water quantity management, and urban wastewater treatment in the region between Rotterdam, Schoonhoven, and Zoetermeer in South Holland province. The organization manages four distinct water levels within its jurisdiction and operates an extensive infrastructure network including pumping stations ('gemalen'), water locks (such as Snelle Sluis and Zevenhuizer Verlaat), dyke and quay systems, the Zuivering Kralingseveer wastewater treatment facility, and innovative climate-adaptation assets such as the Urban Waterbuffer Museumpark (underground sand-layer storage), Waterplein Benthemplein (1.7M liter storage square), and the Kruisplein parking garage water storage (2.4M liters). The organization also runs a 2,581m² biodiverse green roof with 300m³ integrated water storage at Concert- en Congresgebouw De Doelen, plus the Themista® initiative for circular water and resource recovery from wastewater.

HHSK serves a base of residents, businesses (notably greenhouse horticulture operations in Bleiswijk), municipal governments (Rotterdam, Zuidplas), and provincial authorities (Zuid-Holland), with statutory enforcement powers including BOA officials. The business model is funded primarily through waterschapsbelasting (water board taxes) levied on properties in the jurisdiction, supplemented by permit fees, levies on commercial entities, and EU co-funded project grants (e.g., LIFE SWITCH2O). Digital distribution channels include the 'Mijn HHSK' self-service portal, interactive infrastructure maps, an open data portal with real-time water level and quality measurements, plus community engagement via 'Weerbaas' and 'Waterbaas' educational programs. The organization is governed by an Algemeen Bestuur and led by Dijkgraaf Pieter van de Stadt, with hoogheemraaden including Cor Habben Jansen, Arjen Hazelebach (Afvalwaterketen), and Jos Verdoold.

Expansion highlights5 records

Broad incumbents

• Dunea: Dutch drinking water company serving the South Holland dune region (overlapping with HHSK's geography). Provides drinking water production and distribution rather than full water board services, but operates in the same regional water ecosystem and is directly regulated by HHSK's permitting and discharge oversight.
• Vitens: Largest drinking water utility in the Netherlands, supplying potable water to millions of households and businesses. While focused on drinking water production/distribution rather than the full waterschap mandate, it is the most natural adjacent incumbent operating in the Dutch water value chain that HHSK's regulatory work directly intersects.

Direct peers

• Waterschap Amstel, Gooi en Vecht: Dutch waterschap serving the Amsterdam metropolitan region with water management, wastewater treatment, and dyke maintenance. Comparable statutory authority and tax-funded model with strong urban water management focus similar to HHSK's Rotterdam work.
• Wetterskip Fryslân: Another Dutch waterschap with a comparable statutory mandate for water management, wastewater treatment, and dyke safety; explicitly mentioned in HHSK's data as the lead partner on the EU LIFE SWITCH2O WaterSchoon project. Closest functional and structural peer in the Dutch water board network.
• Waterschap Hollandse Delta: Dutch water board serving the southern South Holland/Zeeland island region with the same statutory mandate as HHSK. Comparable in dyke safety, water quality, and wastewater treatment responsibilities, particularly relevant given overlapping low-lying delta geography.
• Waterschap Zuiderzeeland: Dutch water board covering Flevoland, focused on water management and dyke safety in polder areas reclaimed from the former Zuiderzee. Highly comparable to HHSK in managing low-lying reclaimed land, pumping station networks, and waterschapsbelasting-funded operations.
• Waterschap Rivierenland: Dutch water board responsible for water management, flood defense (including major river dykes), and wastewater treatment in the Gelderland/South Holland river area. Comparable in scale and mandate, particularly relevant given its heavy focus on dyke safety in low-lying polder areas similar to HHSK.
• Hoogheemraadschap van Delfland: Neighboring Dutch water board covering the Delft, Westland, and Schiedam area. Operates with the same waterschap statutory framework, regional monopoly, and waterschapsbelasting funding model, serving an overlapping South Holland geography.
• Hoogheemraadschap Hollands Noorderkwartier: Large Dutch water board in North Holland covering water management, dyke maintenance, and wastewater treatment. Functions under the same waterschap legal framework with comparable scale, climate adaptation challenges, and operational scope to HHSK.

Others

• Royal HaskoningDHV: Major Dutch engineering consultancy with extensive water management and climate adaptation expertise, frequently engaged as a contractor/consultant by waterschappen including on urban water and flood defense projects. Comparable ecosystem participant that HHSK partners with on infrastructure design and project execution rather than direct competitor.
