WRM has successfully completed more than 50 environmental impact studies ranging from small approval modifications to major greenfield projects.
Our environmental impact studies typically include a review of background information on water quality and quantity, modelling to quantify impacts, and the development of mitigation and management measures. We liaise with project design teams to ensure consistency between the impact assessment and infrastructure design.
We understand the key regulatory requirements and preferences for impact studies and deliver comprehensive assessments that address regulator and community concerns. Our experience helps us to minimise delays associated with requests for further information.
We also assist our clients with pre-approval liaison with regulators and other stakeholders, as well as post-approval design of management systems and management plans.
