What Rehydro does

Rehydro is a Dutch water management company headquartered in Breda, founded in 2009 (with operational roots tracing to 2007 via the Arnhem Centraal WKO system). The company positions itself as a sustainable water partner for industrial companies, commercial buildings, and municipalities in the Netherlands. It operates three interconnected product lines under a single unified offering: "Duurzaam water" (sustainable water — industrial water delivery, wastewater purification, and reuse stimulation), "Warmte en koude" (heat and cold — WKO thermal energy storage, WKD heat/cold extraction from drinking water, and residual heat utilization), and "Advies en beheer" (advisory and management — water quality, safety, and smart installation management for buildings).

The underlying technology is industrial water purification operations and Dutch-building-scale thermal energy systems (WKO, WKD). Rehydro operates, maintains, and exploits customer-owned or co-owned installations on a recurring managed-service basis rather than selling discrete units. Pricing is not publicly disclosed; solutions are quote-based, project-specific, and require on-site consultation, consistent with a B2B enterprise field-sales motion.

Revenue is generated through four streams: recurring water supply services, recurring industrial water purification operations, managed services for WKO/WKD system operation, and professional advisory services. Customers include mixed industrial and public-sector logos (Arnhem Centraal, Sensus Roosendaal, Chassé Breda, Bedrijventerrein Roerstreek, Gemeente Tholen, High Tech Campus Eindhoven), with municipal/government as a non-primary segment. The company is privately held, with no disclosed investors, funding rounds, M&A, or leadership team; it is actively operating and hiring, with 12 vacancies listed.

Core offering

Rehydro delivers sustainable water, purifies wastewater, and stimulates water reuse for industrial customers, while also providing heating and cooling solutions for buildings through WKO (thermal energy storage), WKD (heat/cold extraction from drinking water), and residual heat recovery. In addition, Rehydro offers advisory and management services covering water quality, water safety, and water installation management in buildings. Together, these three service areas (Duurzaam water, Warmte en koude, Advies en beheer) form an integrated water and energy management offering operated by Rehydro's specialized team across the Netherlands.

The first is Duurzaam water (Sustainable Water), which covers water delivery, wastewater purification, and reuse stimulation for industrial applications. The second is Warmte en koude (Heat and Cold), providing sustainable heating and cooling through WKO (thermal energy storage), WKD (heat/cold extraction from drinking water), and residual heat recovery. The third is Advies en beheer (Advisory and Management), offering water quality and safety expertise, water installation management, and smart monitoring solutions. Together, these services form a comprehensive water management ecosystem focused on sustainability and supply reliability.

Broad incumbents

• Pentair: Global water treatment and flow technology company serving industrial, commercial, and residential customers. Tangentially comparable to Rehydro on industrial water purification, though Pentair is primarily equipment-oriented.
• ENGIE: Global energy and utility services group with significant Dutch district heating/cooling and building-energy operations. Comparable to Rehydro's Warmte en koude practice but at much larger scale and across multiple European geographies.
• Veolia Water Technologies: Global water-treatment technology and services arm of Veolia, serving industrial and municipal customers. Overlaps with Rehydro's industrial water purification and reuse business but at vastly greater scale and broader geographic reach.
• Xylem: Global water technology company providing pumps, treatment, and digital solutions for utilities and industry. Comparable on industrial water and wastewater treatment capability, but Xylem is much larger and equipment-led rather than service-led.
• Ecolab (Nalco Water): Global provider of water, hygiene, and energy services to industrial customers, including boiler-feed and cooling-water treatment. Comparable to Rehydro's industrial water purification and reuse value proposition, especially for process-water applications.

Emerging players

• Hydraloop: Dutch company developing decentralized water recycling and reuse devices for buildings and small communities. Overlaps with Rehydro's Duurzaam water reuse value proposition but is product/hardware-led rather than service/utility-led.

Direct peers

• Desah: Netherlands-based operator of ATES (WKO) installations and thermal-energy infrastructure for buildings and districts. Directly comparable to Rehydro's heat-and-cold operating model.
• IF Technology: Dutch specialist in aquifer thermal energy storage (ATES/WKO) and subsurface energy systems. Highly comparable to Rehydro's WKO/WKD practice, though IF Technology is more consultancy-led while Rehydro also operates assets directly.

Regional players

• Brabant Water: Drinking-water utility serving the North Brabant province where Rehydro is headquartered. Comparable on water-supply operations and Dutch drinking-water regulatory expertise, but operates as a public utility serving residential demand rather than industrial/buildings accounts.
• Eneco: Dutch energy company operating district heating/cooling networks and sustainable building-energy solutions in the Netherlands. Comparable to Rehydro's WKO and building-heating/cooling business, though Eneco is a large multi-utility rather than a niche specialist.
