About the business unit

Our Water Utility Division and Water Consultancy Division both have ambitious growth plans aligned with the significant investment needs of AMP8 (2025–2030) and the broader water sector, particularly in the development of Strategic Resource Options to address future water supply challenges. We are proud of our strong reputation in the industry, which is allowing us to expand our business across both divisions.
