Services
Wastewater Treatment Plant Design
We design custom wastewater treatment systems for industries and municipalities. Our engineers create energy-efficient solutions using technologies like ANRUPAnammox, which reduces energy use by 60% compared to conventional methods. Our designs consider site-specific factors including flow volumes, contaminant types, and regulatory requirements.
Environmental Impact Assessment
Our specialists prepare comprehensive environmental impact assessments for development projects. We evaluate potential effects on local ecosystems, groundwater quality, and air quality while considering cumulative impacts. Our assessments help clients meet regulatory requirements and implement mitigation strategies for sustainable development.
Nutrient Management Plans
We develop science-based nutrient management plans that optimise irrigation areas while protecting environmental values. Our risk-based approach considers soil chemistry, meteorological factors, and vegetation needs to create compliant solutions that often require 30% less land than conventional methods.
Contract Research Services
Our laboratory conducts water and wastewater testing for government agencies and private clients. We partner with universities to deliver research projects on topics like greenhouse gas emissions from treatment plants and organic coagulant development, combining academic expertise with practical engineering applications.
Urban Water Management
We create integrated water management plans for urban developments. Our engineers model stormwater systems, groundwater risks, and reuse opportunities to help clients reduce water consumption while maintaining regulatory compliance. Recent projects have delivered cost savings exceeding $1 million through optimised management strategies.

Report
Raj and the team from Environmental Engineers International Pty Ltd entered a competitive tender process for a new community wastewater treatment system for a local caravan park. We were looking for innovative ways to solve an odour issue and implement and new system in a environmentally sensitive area. Raj and the team presented a well thought out approach that solved the odour issue and went above and beyond to ensure that local trades were consulted and supported in installing and implementing the solution. The proposal for the new system was concise, backed up by relevant data and provided

Report
In December 2019 Raj and his team assisted the Queen Elizabeth Park Trust Board to find a solution to an odour issue created by an outdated water water treatment system in a caravan park we manage on behalf of the community. We have been able to maintain the existing system, deal with the odour issue all while EEI completed a masterplan for the highly sensitive site. The masterplan has provided a series of recommendations which are currently being considered by the relevant stakeholders. EEI took the board through the process, educating the members about the various options and managed the expectations
