Celebrating 30 years
As we celebrate our 30th anniversary, it’s important to take the time to reflect on how our
business has prospered. We would also like to recognise that it is through the dedication of our
employees and the relationships we have built over the years with you, our clients, and our
partners that have made TRILITY the company it is today.
TRILITY was incorporated on 7 August 1991, from its humble beginnings in Australia as Northwest Water. Over the three decades, TRILITY
has transitioned from Northwest Water to United Utilities Australia to TRILITY, and it has seen three owners. Initially United Utilities (formerly
Northwest Water), Mitsubishi Corporation acquired the Company in 2010, and in 2018 Beijing Enterprises Water Group became our new
Shareholders. Our first contract commenced in Victoria in 1993 with the award of Yan Yean Water Treatment plant, and from, there we have
continued to grow.
Over the years, we have delivered hundreds of small to large projects. Today, we have over 300 employees operating 52 water, wastewater
plants, and reuse schemes, 132 pumps stations, and 585 km of network pipelines. We treat over 1.8 GL of water per day, and process over 60k
tonnes of biosolids per year, and service over 400 facilities across Australia and New Zealand.
All of which could not have been achieved without the support of our clients and partners and the communities in which we serve, and the
continued commitment from our employees and shareholders. We look forward to further expanding and diversifying our portfolio of
services to ensure we continue to meet the needs of the ever-changing water sector.
