The augmented treatment plants were designed to use Biological Nutrient Removal technology to reduce nitrogen and phosphorus and include chemical dosing to meet requirements.
The 3 new plants were constructed on 3 separate greenfield sites, several kilometres apart, under a single coordinated contract, with separate construction teams dedicated to each site under the central control of a single project manager.
Comprehensive, integrated project planning documentation was required. Central control allowed coordination of procurement and additional flexibility to reallocate personnel and plant resources to address contingencies. A flexible combination of sequential and parallel task programming maximised utilisation of available resources, enabling the site-specific challenges of each of the 3 sites to be addressed without compromising the overall contract outcomes.
