WaCo

What WaCo does

WaCo Wassertechnik Consult GmbH is an independent German engineering consultancy founded in 1994 in Hamburg by Dr.-Ing. Oliver Debus as a spin-off from Ingenieurbüro Preussner. The firm specializes in reducing operating costs for industrial clients through three integrated service lines: energy management consulting, water and wastewater treatment engineering, and material efficiency advisory. Its client base spans 16 industrial sectors in Germany including breweries, chemicals, electroplating, beverages, cosmetics, plastics, food, metals, mineral oil, paper, IBC/tank cleaning, and laundries, with named enterprise customers including BP, Shell, Aurubis AG, DOW, PepsiCo Germany (Vivaris), AIRBUS, ArcelorMittal, Exxon, FROSTA, Smurfit, ZENTIS, and Warsteiner.

WaCo's technical portfolio combines proprietary physical-chemical water treatment technologies (diamond electrode reactor with 100% OH radical yield at 3V for oxidizing recalcitrant pollutants including PFOS; UV free-surface reactor for non-submerged oxidation) with biological treatment systems (bio-fixed bed, anaerobic reactors with biogas recovery) and membrane-based recycling systems (ultrafiltration, reverse osmosis). The firm supplements this engineering depth with regulatory and financial advisory services, holding BAFA, KfW, and Effizienz-Agentur NRW authorizations that enable subsidized consulting engagements covering 50-80% of costs. Documented customer outcomes include average annual savings of €631,176 per client with a 0.7-year payback, €4.17M/year in refinery projects, €1M+/year at Aurubis AG since 2002, and 80%+ water recycling rates in food industry plants.

WaCo operates as a professional services firm with no external investors, no disclosed subsidiaries, and no distribution beyond direct B2B consulting engagements led personally by Dr. Debus. Revenue is generated through consulting fees for efficiency checks, engineering design, and project implementation support, often facilitated through government subsidy programs that substantially reduce client out-of-pocket cost. The firm has remained privately held and structurally unchanged since founding, with Dr.-Ing. Oliver Debus serving as the sole managing shareholder and primary point of contact for all engagements.

Product overview

WaCo Wassertechnik Consult GmbH is an independent engineering consulting firm offering a comprehensive portfolio of industrial water treatment, wastewater treatment, recycling, energy management, and material efficiency solutions. The core product portfolio centers on physical-chemical water treatment technologies (Diamond Electrode Reactor, UV Free Surface Reactor) and biological treatment systems (Bio-Fixed Bed, Anaerobic Reactors with Biogas). These are complemented by membrane-based treatment and recycling systems (membrane filtration, reverse osmosis, ultrafiltration) and process water recycling plants. On the energy side, WaCo offers consulting services for ISO 50001 energy management system implementation, efficiency checks (heating, cooling, compressed air, process optimization), boiler house optimization, CHP/BHKW systems, and heat recovery systems, along with regulatory consulting for EEG surcharges, grid fees, and energy tax refunds. The company also provides material efficiency consulting across industries and grant/funding advisory services through BAFA and KfW programs. The offering is structured as a service portfolio rather than a packaged software product, with each technology or service offered as a distinct consulting/engineering engagement tailored to the client's industrial context.
