The proposal is to extend the Exmouth water supply borefield, and includes:

• extending the existing borefield, to the west (equipping existing bores) and to the south (drilling and equipping new bores);
• increasing the long term supply capacity from approximately 760 million litres per year (ML!yr) to 1,025ML!yr;
• constructing four dedicated stygofauna monitoring bores (two within the proposed borefield extension and two to the south of Shothole Canyon Road, which has been identified as future National Park) and two nests of dedicated saltwater interface monitoring (SWIM) bores. These will be used for long term monitoring;
• constructing seventeen water level monitoring bores, which will also be monitored for stygofauna;
• upgrading the infrastructure.
