Reviews of Environmental Factors

Environmental impact assessments

We assess the potential environmental impacts of our projects before starting construction. The assessment is documented in a Review of Environmental Factors (REF). Where we're seeking comments from our stakeholders and community, REFs are exhibited on Sydney Water Talk. The REFs published below are for projects that cost more than $5 million or require specified environmental or heritage permits.
