Keeping Sydney’s Taps Flowing: Prospect Water Filtration Plant

Ensuring safe, reliable drinking water each time Sydney’s ever-growing population turns on a tap is a significant and evolving challenge for the local water utility. SUEZ’s Prospect Water Filtration Plant is on the frontline in meeting this essential need.

The mission

Glass half full

In 1967, recurrent drought and rapid population growth brought the need for a more secure
water supply for Sydney’s residents into sharp focus.
In 1993, SUEZ, as part of the Prospect Water Partnership, was awarded a 25-year contract to design, build, operate and maintain the Prospect Water Filtration Plant (PWFP) to meet increasing demand into the future.
Opened in 1996, the PWFP remains one of the largest water filtration plants in the world.

Partners in efficiency

The construction of Prospect Water Filtration Plant in the 90s was a part of the evolution to meet the increasing demand for reliable water supply in Sydney. In 1993, SUEZ, as part of the Prospect Water Partnership, which also comprised at that time Lend Lease Water Services and P&O (Prospect), was awarded the contract to design, build, operate and maintain the plant for 25 years. Since the opening on the 11th September 1996, the Prospect Water Filtration Plant has been providing consistently safe and reliable drinking water that complies with Australian Drinking Water Guidelines.
Today, operated by SUEZ, the plant is the largest water filtration plant in Sydney and supplies reliable drinking water to 85% of Sydney’s population, or approximately 4 million residents.

The Prospect Water Filtration Plant has been meeting most of Sydney’s drinking water needs for more than 20 years.

Operational reliability, every day

With the compact and cost-effective design in place, the focus turned to ensuring the operational reliability and continuity of the plant.
Robust operation and maintenance practices, including a highly automated and advanced process management system, control the process and the finished water quality.
Ongoing technical training and regular skill reviews are undertaken to ensure employees are equipped with the latest technical knowledge, and ongoing investment in systems and innovations drive continuous improvement.
From day one, the plant has provided consistently safe and reliable drinking water to 85 per cent of Sydney’s population, or approximately 4 million residents. At capacity, it can supply around 3,000 million litres of drinking water each day.
