• Servis in SeparationmajorImplementation/ SI/ Consulting Partnervandervalk+degroot performed cleaning of sludge digestion tanks at RWZI Elburg for waterschap Vallei en Veluwe, in subcontract of Servis in Separation. The approach plan was jointly written and the company leveraged its 2013 experience from Leeuwarden. This partnership was instrumental in winning the contract.
• Mobilis / TBImajorStrategic or Co-development Partnervandervalk+degroot was hired by Mobilis/TBI to clean selectors, anaerobic tanks and distribution works at AWZI Zwanenburg.

Direct peers

• A.Hak Industrial Services: Dutch utility construction and industrial services contractor focused on pipelines, cables, and underground infrastructure. Highly comparable in scope: pipeline construction, inspection, and rehabilitation for utility and industrial clients across the Netherlands.
• Van der Ven: Dutch industrial services and cleaning contractor offering specialized tank, sewer, and industrial cleaning services. Comparable as a direct Dutch specialist competitor in wet infrastructure and industrial cleaning.
• Mourik Industry & Maintenance: Dutch industrial services contractor providing cleaning, maintenance, and shutdown services to chemical, petrochemical, and utility clients. Comparable for specialized wet infrastructure and industrial cleaning work in the Netherlands.

Others

• Stichting RIONED: Dutch sector foundation for urban drainage. Not a competitor but a strategic ecosystem partner (RibX standard) whose policies and standards directly shape the addressable market for sewer management services in the Netherlands.

Broad incumbents

• Royal HaskoningDHV: Dutch engineering and project management consultancy with a dedicated water technology practice. Comparable as a Dutch-headquartered player in the water/wastewater value chain, though focused on advisory and design rather than field execution.
• Suez Water Technologies & Solutions: Global water and wastewater services major. Comparable as a much larger incumbent operating across the same wastewater service value chain, though at a global rather than municipal-Dutch scale.
• BAM Infra Nederland: Major Dutch infrastructure contractor with sewer and pipeline capabilities. Already a partner of vandervalk+degroot via CIBOOR (Haarlem) and represents the broader-incumbent category of multi-disciplinary construction firms competing for the same municipal contracts.
• Heijmans Infra: Large Dutch construction and infrastructure company with water and sewer network services. Comparable as a broader incumbent active in Dutch municipal water/sewer contracts but without vandervalk+degroot's specialization depth.
• Veolia Water Technologies: Global environmental services major with extensive wastewater treatment and network services. Comparable as a broad incumbent in the same wet infrastructure domain, but with very different geographic and customer scope.

Emerging players

• Aquatech: Global water technology specialist focused on treatment, desalination, and water reuse. Comparable thematically in advanced water/wastewater technology, though operating at different scale and segment than the Dutch sewer-cleaning niche.
