What d.s.s.v. does

D.S.S.V. NV (DSSV) is a family-owned Belgian industrial services company, part of Group Daniëls, that delivers an integrated sewer and waste-management offering across Belgium and neighboring countries. The company provides sewer cleaning and unblocking, BELAC-accredited ISO 17025 sewer and pipeline inspection, trenchless sewer renovation (including Quick-lock, Shortliner, Brawoliner, UV lining, and open-trench methods), industrial cleaning and waste removal for chemical baths, reactors, silos, tanks, and flooded sites, oil-tank sanitization and decommissioning, and liquid-tight container rental. Its tank and kipper transport division, Transpo Daniëls, runs 15-20 tank trailers of approximately 30m³ and holds ADR licenses for France, the Netherlands, Germany, and Luxembourg. A separate LDO entity provides domestic cleaning under the Flemish service-voucher scheme, and TAVYMA BV and DJFD round out the group under the Daniëls family umbrella.

DSSV's underlying technology is asset-heavy and procedure-driven: milieubewuste recycler combiwagens that reclaim process water for uninterrupted cleaning, high-pressure combination trucks reaching 400 bar, self-propelled tractor robot cameras with tilt-angle sensors producing EN13508-2 coded inspection reports, and a 7.5-hectare secondary site in Ham with private dock access for chemical plant maintenance and bulk logistics. Core certifications include VCA**, ISO 9001, ISO 17025 (BELAC), OVAM tank-transport permits, and recognition as collector, trader, and broker of hazardous waste.

The business model is professional services sold direct-to-customer: per-assignment billing for ad-hoc work, fixed recurring contracts with enterprise and municipal clients (Aquafin, Fluvius, Indaver, Renewi, Suez, REMONDIS, Bionerga, Aldi, Carrefour, Willemen, Kumpen, Besix, City of Antwerp), and event-driven engagements with festivals such as Pukkelpop and Tomorrowland. Distribution is exclusively direct (phone, email, website forms, and Flemish service vouchers for the LDO domestic line); there are no resellers or channel partners. The third generation of the Daniëls family completed its leadership transition in 2023 (Next Gen Award), and the group celebrated its 50th anniversary in June 2026, reporting consolidated revenue above €30 million after doubling over the prior five years.
