Key Challenges

The design solution presented to our client by Murphy will meet these challenges and delivering safe and reliable water supplies to customers.

Murphy assumed responsibility for managing the existing water treatment assets at the commencement of the project. Operation of these facilities was reviewed and optimised as part of our delivery strategy so we could ensure water supply and quality to residents and businesses were not affected by our works.
