Yarra Valley Water had 906,803 customers at 30 June 2025, up 13,323 on a year earlier. Several of its growth projects sit in Melbourne's north, where the Northern Growth Corridor's population is expected to exceed 300,000.
Sewage capacity first
The Craigieburn Sewage Transfer Hub, which sends sewage on to Melbourne Water's Western Treatment Plant, has completed a A$20 million expansion that added two storage tanks. Yarra Valley Water plans up to 8 tanks and a future capacity of 120 ML there. The expansion is shown under Yarra Valley Water's completed works (confirmed 10 November 2026).
Recycled water for new suburbs
At Wollert, a new Aurora recycled water plant is in early design with John Holland under a contract of about A$5 million. It would lift Class A capacity from 2.9 ML/day to 10 ML/day, with commissioning expected around 2030. The recycled water network already runs 800 km of mains: 48,000 homes and businesses were served in 2023-24, and capacity reached over 55,000 in 2024-25.
Paying for growth
Capital expenditure was A$382.8 million in FY2024-25, against A$1,962 million approved by the Essential Services Commission for 2023-28. Borrowings were A$4,193.3 million at 30 June 2025 and cash interest cover was 1.83 times. Dividends paid to the State were A$49.7 million, against a budget of A$14 million.
Service under strain
Reliability has weakened over the same period: 7,527 customers had three or more unplanned interruptions in 2025-26, above the limit of fewer than 7,000. The 2028-33 price review, with Yarra Valley Water's submission due in September 2027 and a decision in June 2028, will set the next capital program.
