Aquasure

What Aquasure does

AquaSure Pty Ltd is a special purpose vehicle incorporated in Victoria, Australia in 2009 to deliver the Victorian Desalination Project under a 30-year Public Private Partnership with the Victorian State Government, with the concession running until September 2039. The company finances, designed, built, operates and maintains a 440 megalitre-per-day seawater desalination plant at Wonthaggi using a two-pass reverse osmosis process with Dual Media Pressure Filters and proprietary energy recovery devices, plus an 84 km underground water transfer pipeline to Berwick with seven delivery points (five operational, two planned) serving Melbourne, Geelong and regional Victorian communities.

Under the PPP, AquaSure receives contract payments from the Victorian Government (funded via Melbourne Water) in return for producing desalinated water on an annual order basis, with flexible ordering between 0 and 150 billion litres per year and latent expansion capacity to 200 billion litres. The total maximum net present cost over the 30-year concession is A$5.7 billion assuming full 150 GL/year orders, against a fixed A$3.5 billion construction price funded by A$3.7 billion in debt from more than 30 financial institutions and A$0.8 billion in equity from ten shareholders. Operations and maintenance are delivered by Watersure, a SUEZ–Ventia joint venture, through a team of more than 80 staff 24/7, supported by AusNet Services for the 220 kV HVAC power cable infrastructure.

AquaSure has no diversified revenue streams, no other customers, and is structurally scheduled to cease operations after the concession ends, at which point the plant and pipeline are handed back to the Government debt-free and in full working order. All operational electricity (up to 90 MW at full production) is offset by renewable energy certificates, the CEO has committed the company to net-zero Scope 1 and Scope 2 emissions, and operations are conducted under an EPA licence with 221 strict environmental performance requirements across 38 areas.

Revenue model

1. Government Contract Payments: As a Public Private Partnership (PPP), AquaSure receives contract payments from the Victorian State Government (funded by Melbourne Water) for financing, designing, building, operating and maintaining the Victorian Desalination Plant. The total maximum net present cost over the 30-year concession period is $5.7 billion assuming water orders of 150 billion litres per year.
2. Desalinated Water Production: Water production services provided at the request of the State Government. AquaSure does not own the water produced; it desalinates seawater for delivery to Melbourne Water and other authorities in quantities specified each year by the Government.

Core offering

Aquasure finances, designs, builds, operates and maintains the Victorian Desalination Plant under a 30-year Public Private Partnership with the Victorian State Government. The plant uses two-pass reverse osmosis to produce up to 150 billion litres of potable water per year, delivered through an 84 km pipeline to Melbourne Water, South Gippsland Water, South East Water and other authorities for distribution to Melbourne, Geelong and regional communities. Operations and maintenance are performed by Watersure (a SUEZ-Ventia joint venture) through September 2039.

Product overview

The Victorian Desalination Project is a unified infrastructure system comprising a seawater desalination plant at Wonthaggi, an 84 kilometre water transfer pipeline, and associated marine structures. The plant uses reverse osmosis (membrane-based) desalination technology and is operated and maintained by Watersure under contract through 2039. Environmental management and an ecological reserve are integral to the project's operations, with all power consumption offset by renewable energy certificates.

Direct peers

• Cadagua (Ferrovial): Spanish water infrastructure EPC and operator with significant SWRO concession portfolio (e.g., Tampa Bay, Mundaring); directly comparable to Aquasure's build-own-operate-transfer PPP model.
• IDE Technologies: Israeli-origin technology provider and operator of SWRO desalination plants globally, including the Sorek and Carlsbad plants; competes with AquaSure's two-pass RO design in large municipal seawater desalination tenders.
• SUEZ (now part of Veolia): Global water treatment and desalination operator; forms the Watersure JV with Ventia that operates and maintains the Victorian Desalination Plant through 2039, and competes directly with Aquasure's offerings in international SWRO concessions.
