The DWTP Mundaring celebrates its 10th anniversary

Last month of April, we celebrated the 10th Anniversary of the PPP (Public Private Partnership) Project of the Mundaring DWTP between the Water Corporation and Helena Water (a consortium made up of ACCIONA, TRILITY, and Royal Bank of Scotland, now abrdn) to design, build and operate the plant, located 34 km east of Perth (Western Australia), for 35 years.

To commemorate this very special milestone, we brought together current and former employees (including managers and supervisors) who worked on the project for a tour of the the facilities followed by a special lunch.

The Mundaring DWTP was the first DWTP project of ACCIONA’s water business in Australia. Not only that, this water treatment plant has some particular elements that make this project unique such as its innovative design which is capable of treating three different water sources; has zero discharge into the environment; and incorporates sustainable management of the produced sludge. The plant reduces organic matter before subsequent advanced treatment that then prepares the water to be supplied to the largest drinking water network in the world.

The plant has an initial capacity to treat 165,000 m3 of water per day, which can be expanded up to 240,000 m3 per day. It is the only water source for the more the 9,601 km distribution system called Goldfields & Agricultural Water Supply (GAWS) that has a population of over 100,000 customers, farms and various important mines for the extraction of Gold, Lithium and Nickel.

From a social perspective, the project has safety statistics that are significantly lower than the sector average. Furthermore, the O&M team is a diverse and multicultural group with people from a range of countries including Australia, Scotland, Iran, Sri Lanka, India, Malaysia, Pakistan, and Spain who are active in both funding and participating in a range of local community projects.

The project has been the recipient of a number of Awards such as Contract of the Year 2012 by Global Water Intelligence and Infrastructure Partnerships Australia.
