This project formed part of a Framework Agreement with SA Water and involved the design and construction of new filter block underdrains and replacement filter media. The project scope included the removal and disposal of existing concrete underdrains and filter media, reinstatement of concrete launders and pipework, a new filter block underdrain system, filter gravel, sand, anthracite, filter baffles and air scour pipework. Close negotiation with the plant operators allowed multiple filters to be upgraded concurrently, allowing the project to be completed six weeks ahead of schedule and well under budget.
