Environmental Engineers International

What Environmental Engineers International does

Environmental Engineers International (EEI) is a Perth-headquartered, founder-led specialist engineering firm established in 2001 that focuses on wastewater treatment and environmental management for industrial and government clients. The company develops and deploys proprietary treatment technologies, most notably the ANRUP anammox process for energy-efficient chemical-free nitrogen removal, the EEI-HART high-rate anaerobic reactor, and the SPORE technology (patented in Australia, Vietnam, and India). These are complemented by a Nutrient Balance Model for irrigation area estimation and an in-house laboratory for sampling and testing.

EEI generates revenue primarily through professional services: concept and detailed engineering design, EPCM consulting, troubleshooting of underperforming treatment plants, environmental impact assessment, and contract research for clients including UN agencies, government bodies, and major corporates. A secondary hardware/chemical delivery revenue stream supports its treatment solutions. Customers span meat processing (Dardanup Butchering Company, Mount Barker Chicken Abattoir), mining (BHP, South32, Adaman Resources), oil and gas (Woodside), food and beverage (White Lakes Brewery), tourism, agriculture, education, and government (UNFCCC, Water Corporation, WA Department of Water and Environmental Regulation). Pricing is custom project-based with multi-year contracts; no standard pricing is disclosed.

The company is privately held as a Western Australian proprietary limited company, with no disclosed external investors, parent entities, or subsidiaries. Distribution is entirely direct enterprise engagement, supported by founder-led industry recognition (multiple Engineers Australia and Australian Water Association awards for CEO Dr Raj Kurup), university research collaborations (UWA, Murdoch, University of Missouri-Columbia), and published technical output of more than 60 papers and reports. Operations are run from a single Perth office with ISO 9001, ISO 14001, and ISO 45001 certifications.

Scale indicators11 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Xylem: Global water technology company providing pumps, treatment systems, and smart water solutions. Xylem overlaps with EEI's industrial wastewater treatment work and is a potential acquirer or threat to EEI's patented nitrogen removal technology.
• SUEZ Water Technologies & Solutions: Global water and waste management company providing industrial water treatment, consulting, and digital water solutions. SUEZ competes with EEI for industrial wastewater treatment contracts and offers overlapping consulting and engineering services.
• AECOM: Global infrastructure consulting firm with a large water and environmental services practice. AECOM competes with EEI for industrial wastewater and environmental impact assessment mandates from large resource clients such as BHP and Woodside, but operates at much greater scale across a broader portfolio.
• WSP Global: Global engineering consultancy with a strong water and environment practice. WSP competes with EEI in environmental impact assessment, water treatment design, and industrial client advisory across mining and oil & gas sectors.
• Stantec: International engineering, architecture, and environmental consulting firm with established water and wastewater treatment services. Stantec serves many of the same industrial and municipal clients as EEI at significantly larger scale.
• Veolia Water Technologies: Global water treatment technology and services provider serving industrial and municipal customers. Veolia competes with EEI on industrial wastewater treatment across mining, food & beverage, and oil & gas sectors, but at much larger scale and with a more productized offering.
• Jacobs Solutions: Global professional services firm with deep water and environmental engineering capabilities. Jacobs competes for major industrial wastewater and ESG projects globally, often as a turnkey EPCM provider similar to EEI's delivery model for projects like Subiaco WWTP.

Emerging players

• Fluence Corporation: Aspen Technology-affiliated provider of decentralized water and wastewater treatment solutions. Fluence offers packaged, modular treatment systems targeting industrial and municipal customers, partially overlapping with EEI's HART and ANRUP product offerings.

Regional players

• Water Research Australia: Australian water industry research and development organization collaborating with utilities and universities. While primarily a research body rather than a direct competitor, it shares EEI's Australian water sector focus and complements EEI's university research partnerships.

Direct peers

• GHD: Australian-headquartered global engineering, architecture, and environmental consulting firm. GHD and EEI both deliver environmental consulting and wastewater treatment engineering to mining, oil & gas, and government clients across Australia, making them direct competitors in the WA/Western Australian market.
