Water

Delivering innovative engineering solutions for sustainable water systems and infrastructure.

We are involved in big and small aspects of the water industry. We help out on projects from the concept to the demobilisation of the project offices.

We provide design and constructability input at early contractor involvement stage. We design permanent structures and temporary works structures and undertake all construction phase services. Our team has extensive experience in trenchless solutions and relining large and small tunnels.

North West Treatment Hub

The North West Treatment Hub plays a critical role in servicing Sydney’s rapidly growing north-west. By coordinating upgrades across the Castle Hill, Rouse Hill and Riverstone water resource recovery facilities, the hub helps improve treatment capacity, resilience and environmental performance.
These upgrades will support future development, enhance operational efficiency, and ensure treated wastewater meets strict environmental standards before being released back into the environment.

Witt's engineers have provided Geotechnical and Temporary Works Design to assist in these upgrades - the scope included but is not limited to; proof roll inspections, pavement design, earthworks, DCP testing, Geotechnical inspections, batter stability, pipe support and more.
