Bergschenhoek Groep

What Bergschenhoek Groep does

Bergschenhoek Groep B.V. is a privately held Dutch family-owned holding company headquartered in Bergschenhoek, Netherlands, coordinating the global activities of its operating subsidiaries. Founded in 1919 by Huig Rook as a sand and gravel trading business (Rook Groep), the group has evolved over four generations into a 350-FTE enterprise operating today primarily in water management and water infrastructure products. Its two core operating subsidiaries are Bergschenhoek Water Technology B.V. (BWT, established 1973), which produces custom-made corrugated steel water basins and potato ventilation ducts, and KWT Group B.V. (acquired 2007), an international producer and supplier of water level management products including stopcocks, valves, weirs, float units, and siphons manufactured from HDPE and stainless steel. The group also offers ROwat-SPS retaining walls and plastic sheet piling solutions.

The group's technology centers on physical manufacturing of steel, HDPE, and stainless steel products for civil engineering, hydraulic engineering, and agricultural storage applications. Differentiators cited in the company's own materials include custom-made product development to customer specifications, a dual-material product range (HDPE and stainless steel), and an ISO 9001-certified quality management system. Operating companies are marketed through dedicated subsidiary websites (mijnwatersilo.nl, kwtwaterbeheersing.nl, rowat-sps.com), trade show participation (Infra Relatiedagen Hardenberg), customer events, and local community sponsorship (BVCB football club since 2008). The group operates across roughly four countries with international distribution led by KWT.

Bergschenhoek Groep generates revenue through direct hardware sales of manufactured products — a model explicitly categorized as hardware sales. Pricing is not publicly disclosed. The business has undergone significant portfolio reshaping: it sold Cox Geelen B.V. in January 2019, then divested its entire ventilation business (R-Vent Netherlands B.V., including Bergschenhoek Luchtcomfort, Spiraliet, and Vespi) to Lindab Group in June 2022, and sold the GWW civil engineering assets of Bergschenhoek Civiele Techniek B.V. to ViaCon in April 2022. Post-divestiture, the group is concentrated on water management and water infrastructure niches. Ownership remains entirely within the Rook family, currently led by fourth-generation co-CEOs Corine Rook and Jeroen Rook, who jointly assumed operational leadership in March 2016 after Gerard Rook's 44-year tenure as Chair. Revenue figures are not publicly disclosed.
