Environmental Engineers International Pty Ltd (EEI) is a multi-award-winning specialist engineering company established in 2001 based in Perth. We operate in the fields of water, energy, resources, land development, environment, and sustainability. EEI provides consulting, detailed and concept engineering, technical advisory, contract research, environmental management, and equipment and chemical delivery services to a variety of private and public-sector clients.

We welcome all manner of project scales and complexities, and we are specialists in wastewater treatment. We commonly provide our services to the meat processing, mining, oil and gas, food and beverages, housing, and tourism industries. We have carried out the design and construction of many wastewater treatment projects across the world, including several specialist projects in Australia and overseas.

EEI has developed award winning wastewater treatment technologies recognised by the Australian water industry. The EEI ANRUPanammox technology for nitrogen removal received the 2017 Australian Water Association (AWA) Research Innovation Award, and the 2016 Innovating for Sustainability Award. The anammox technology is extremely energy efficient and does not require external chemical dosing. Dr Raj Kurup, Director of EEI, was awarded the title of Australia's Most Innovative Engineer 2017 in the Consulting Category from Engineers Australia, and the 2017 Water Professional of the Year Award for his role developing the anammox technology. 

EEI's High Rate Anaerobic Reactor Technology (HART) installed at Dardanup Butchering Company was also a finalist for the AWA Infrastructure innovation award in 2013. The project was recognised for its innovations in combined chemical and biological phosphorus removal, significantly cheaper operating costs for carbon removal, remote monitoring and control system for preventive maintenance and ensuring environmental compliance, and value-added sludge management system.

We look forward to working with you and your organisation to achieve sustainable solutions for your waste, energy, and environmental concerns. Please feel free to contact us to discuss how we can be of service to you.

Sustainability is integral to EEI's engineering philosophy. Our technology can recover waste resources that would otherwise be squandered. EEI's systems can treat incoming wastewater to recover biogas for use operating the plant, produce sludge that can be processed to create a value-added fertiliser product, and treat the water to a quality that allows for irrigation or use on-site depending on the client's needs.

The award-winning ANRUPAnammox technology is EEI's state-of-the-art solution for nitrogen removal. Anammox significantly reduces the energy requirements, lowers sludge production, and eliminates the need for external carbon dosing during treatment.  Our consulting team can identify areas to reduce energy and chemical use in your wastewater treatment operations.


EEI employs a corporate sustainability strategy that establishes positive long-term relationships with our clients, stakeholders, staff and regulating bodies. We look forward to working with you and your organisation to achieve sustainable solutions for your energy and environmental concerns.
