Dewa Projekt

What Dewa Projekt does

DEWA Projekt OÜ is an Estonian private limited company that has operated since 1994 in the water and wastewater treatment equipment sector, serving customers in Estonia and Latvia. The company began as a branch of DWT-Engineering Oy and became an independent legal entity in 1999 under its current name. It functions as the authorized representative for three international manufacturers — Aerzener Maschinenfabrik GmbH (Germany) for blowers and compressors, Colubris Cleantech B.V. (Netherlands) for industrial wastewater treatment plants, and Lackeby Products AB (Sweden) for municipal and industrial treatment equipment — providing sales, factory-certified maintenance, and original spare parts for their products in the Baltic region. Customers include municipal utilities, industrial companies across food processing, chemical, textile, dairy, and pulp and paper, and public sector institutions.

The product portfolio covers the full wastewater treatment train. Aerzen's blowers and compressors (Delta Blower Generation 5, Delta Hybrid belt and direct-driven, Turbo Generation 5plus, Delta Screw compressors) supply aeration air for biological treatment. Colubris's systems span preliminary screening (Curved Screens, ScreenMaster drum screens), primary treatment (Flocculator Type RPF, FlotMaster DAF, SmartDose coagulant dosing, PolyMaster polymer preparation), and secondary biological treatment. Lackeby's equipment handles wastewater screening (ROTO-SIEVE drum screens, bar screens, pre-treatment units), grit and sand treatment, clarification and sludge thickening, screw conveyors and presses, and energy-recovery heat exchangers. Notable technical features include the SmartDose system, which continuously matches coagulant dosing to removable pollution fraction and reports 20–30% chemical-consumption and 15–30% sludge-production reductions, and Lackeby's air-water and sludge-water heat exchangers, which claim up to 15 years of additional rubber-diffuser-membrane service life and sub-1-year ROI on heat recovery.

Revenue is generated through three streams: one-time equipment sales across all three manufacturer lines, ongoing maintenance and professional services with factory-certified quality (notably for Aerzen equipment), and original spare parts supply. Pricing is quote-based and not publicly disclosed. The go-to-market is direct field sales to municipal, industrial, and public-sector buyers in Estonia and Latvia, supported by a product-rich website and integration with the three manufacturers' brand sites. No public revenue, headcount, or ownership disclosures are available, and the company has remained a privately held, independently operating niche distributor.

Scale indicators3 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Grundfos Holding A/S: Danish global pump manufacturer with major presence in water utility, wastewater, and industrial dosing applications. Comparable as a Nordic-headquartered water equipment supplier serving municipal customers across Europe, though focused on pumps rather than treatment process equipment.
• Ecolab Inc: Global water, hygiene, and infection prevention company providing treatment chemicals, equipment, and digital monitoring to industrial and municipal water customers. Adjacent comparable given shared industrial wastewater customer base and chemicals/dosing focus that overlaps with Dewa's SmartDose and PolyMaster product lines.
• KSB SE & Co. KGaA: German manufacturer of pumps, valves, and related systems for water supply, wastewater treatment, and industrial process applications. Comparable as a European water equipment incumbent selling into municipal and industrial customers with overlapping product categories.
• SUEZ Water Technologies & Solutions: International water treatment and services company supplying equipment, chemicals, and digital solutions to municipal and industrial customers. Overlaps with Dewa's end markets but operates at much greater scale with proprietary technology platforms.
• Veolia Water Technologies: Global water treatment major offering engineered systems, services, and mobile water solutions across municipal and industrial markets. Competes in the same wastewater equipment space as Dewa but at vastly larger scale and with broader service offerings.

Direct peers

• Alfa Laval AB: Swedish manufacturer of heat exchangers, separation equipment, and fluid handling systems used in municipal and industrial wastewater treatment. Direct overlap with the Lackeby heat exchanger product line Dewa distributes and similar Nordic industrial heritage.
• Xylem Inc: Xylem is a global water technology company providing pumps, treatment equipment, and aeration systems to municipal and industrial customers. Strongly comparable to Dewa Projekt's portfolio scope (treatment equipment for utilities and industry) and overlapping customer base, though at vastly larger scale.
• H2O Innovation Inc: Canadian water and wastewater treatment solutions provider offering equipment, systems, and aftermarket services to municipal and industrial clients. Most comparable in scale and integrated equipment-plus-service model to Dewa Projekt's regional distribution business.
• Sulzer Ltd: Swiss industrial company manufacturing pumps, mixers, and aeration equipment for water and wastewater treatment applications. Comparable as a manufacturer-supplier of complementary equipment Dewa distributes and as a competitor in the broader municipal wastewater equipment market.
• Andritz AG: Austrian manufacturer of sludge dewatering, screening, and separation equipment for municipal and industrial wastewater plants. Overlaps with Dewa's Lackeby portfolio (screens, screw presses, thickeners) and serves the same end-customer segments.
