[Sydney, Australia] AUD 1.2 Billion Badu Yarragul Water Resource Recovery Plant Commissioned; Reclaimed Water Targets Data Centers

The New South Wales Government unveiled the Badu Yarragul Water Resource Recovery Facility at Kemps Creek on 2026年10月7日, with a project investment of AUD 12亿, put into operation by Sydney Water. The facility currently can treat 3500万 liters/day of wastewater, with plans to expand to 7000万 liters/day, initially serving more than 14万 households and businesses. Sydney Water has confirmed that the facility's Reclaimed Water can be sold to data center operators.

1. AUD 12亿: A New Benchmark for Sydney Water

The Badu Yarragul Water Resource Recovery Facility cost AUD 12亿 and was unveiled by the New South Wales Government on local time 2026年10月7日. The facility's treatment capacity:

• Current scale — daily wastewater treatment volume reaches 3500万 liters, roughly equivalent to 14 Olympic-sized swimming pools.
• Planned expansion — capable of being upgraded to 7000万 liters/day, i.e., doubling the current scale.
• Service scope — initially providing services to more than 14万 households and businesses.
• Construction background — Phase I construction commenced in 2023年8月, undertaken and operated by a consortium led by John Holland, with members including Trility, GHD, and Jacobs.

Sydney Water Managing Director Darren Cleary described the facility as a benchmark for modern water infrastructure and mentioned that the company has a capital investment plan of AUD 140亿 over the next five years.

2. Process Route: MBR + Reverse Osmosis, Biosolids Returned to Land

The facility adopts an advanced treatment combination of Membrane Bioreactor (MBR) + Reverse Osmosis. The Reclaimed Water produced meets non-potable standards, with main uses including:

• Industrial processes — replacing tap water for production stages.
• Agricultural irrigation — providing a stable non-traditional water source for regional agriculture.
• Public space greening — irrigation for parks, green spaces, and urban landscapes.

At the same time, the biosolids produced by the facility will be reused for agriculture and forestry, forming two parallel resource output channels of water and nutrients.

In terms of supporting pipe networks, the facility's pipeline system includes a Reclaimed Water transmission pipeline leading to the Nepean River, and a brine pipeline connected to Sydney Water's existing network at Lansdowne — the destination of the concentrated water was clearly arranged at the design stage, avoiding converting upgrading pressure into secondary pollution.

3. Data Centers: New Buyers of Reclaimed Water

Worth industry attention is that Sydney Water has confirmed the facility's Reclaimed Water may be sold to data center operators. Although the project's environmental impact assessment report did not explicitly list data centers, any supply would be paid for by the customer and would not affect existing users.

This arrangement is not an isolated case. Another sewage treatment plant in Sydney, located at Camellia-Rosehill, is planned for completion before 2032年 and will also provide Reclaimed Water to data centers, demonstrating a systematic regional layout for industrial water demand.

Data center cooling water is currently one of the fastest-growing segments in the global water market. Compared with the intermittent demand of agricultural irrigation, data centers have stable loads, strong payment capacity, and low sensitivity to water prices, and are regarded as one of the highest-quality customer types for Reclaimed Water projects. For Chinese companies expanding overseas, this change in customer structure deserves close attention.

4. Sustainability Requirements: At Least Gold, Striving for Platinum

Sydney Water has imposed clear sustainability constraints on the construction consortium, requiring the project to achieve at least Gold in the Infrastructure Sustainability Council (ISC) rating, with Platinum as an ambitious target. Implementation measures include:

• Recycled Material Pavement — On-site road paving uses recycled materials.
• Glass-Based Pipe Bedding — Glass-based materials are used for pipeline bedding, reducing the consumption of natural aggregates.

Writing sustainability into contract thresholds rather than treating it as a "bonus item" reflects a shift in the procurement logic of large international water projects: carbon footprint and resource circularity are becoming core dimensions of bid evaluation, just like water price and water volume.

V. Industry Observations: Three Lessons Worth Learning

From project model to customer structure, Badu Yarragul offers three references for domestic Reclaimed Water projects:

• Naming Is Positioning — Renaming a "Sewage Treatment Plant" as a "Water Resource Recovery Facility" is not a word game, but an institutional expression of repositioning the facility from a cost center to a resource output unit. In recent years, domestic terms such as "Resource Recovery Factory" and "Energy Factory" share the same origin.
• Front-End Planning of Brine Pipelines — The pain point of many domestic Reclaimed Water projects lies in brine disposal. Sydney built an independent brine pipeline during the construction phase and connected it to the existing network, a practice worth referencing.
• Reserving Capacity for High-Value Customers — Including stable payers such as data centers within the service radius can significantly improve the project cash flow model. In recent years, dedicated Reclaimed Water projects for data centers have been launched intensively in Southeast Asia and the Middle East, with similar projects already implemented in Johor, Malaysia and other locations, featuring MBR + multi-stage RO and a recovery rate exceeding 85%.

Industry analysis suggests that as computing power expansion and water resource constraints intensify simultaneously in multiple regions, the "Reclaimed Water—Data Center" combination will be replicated in more cities. For Chinese environmental protection equipment and solution providers, whoever can deliver modular advanced treatment systems adapted to high-reliability requirements will have the opportunity to enter this rapidly growing supply chain.

TIANYI TECH (TIANYI LIMITED) is rooted in its core businesses of wastewater treatment and Reclaimed Water Reuse, with one-stop service capabilities covering solution design, equipment manufacturing, engineering construction, and project operation. The company provides advanced Reclaimed Water treatment systems for diverse scenarios including data centers, Industrial Parks, and municipal miscellaneous use. Adopting modular and skid-mounted designs, the systems facilitate rapid deployment and phased expansion, and can be customized and iterated according to water quality conditions, climate characteristics, and discharge standards of different countries and regions, helping Chinese environmental technology and equipment go global.
