Reported scope and milestone
Yarra Valley Water appointed John Holland to lead early design of the Wollert Recycled Water Treatment Facility upgrade. The planned capacity is to increase from 2.9 ML/day to 10 ML/day, while the existing facility continues operating as a new adjacent facility is developed.

Engineering interpretation
This appointment covers early design, not an announced full construction contract. The planned increase from 2.9 ML/day to 10 ML/day must remain a future capacity target, and maintaining the existing plant while the adjacent facility is developed creates a continuity and tie-in constraint for later delivery.
Delivery responsibilities
Engineering, design, assessment and advisory appointments must be read within their documented package. The consultant may support planning, approvals, technical decisions or construction interfaces while other parties supply equipment and execute the works. Proposed capacity belongs to the future asset and does not establish present output. Design acceptance, permits and construction completion are separate milestones. The reported role supports those decisions without transferring ownership, operation or all construction responsibility to the consultant; subsequent delivery commitments require their own source evidence.
