Approach to Environmental Assessment

Assessment of the environmental and social impact of options

We have completed detailed environmental and social assessment of all the main options that we are considering (called constrained options). The options have been assessed in component parts, for example the water resource, conveyance and treatment. We welcome your comments on these assessments. There are over 200 assessments in total. We have not published all the assessments here, but instead have provided a list of the assessments. If you would like to receive a copy of any of the assessments please email
