The $144M Mangere Wastewater Treatment Plant upgrade won Gold Award at the 54th ACENZ Innovate Awards held in
Christchurch on 9 August 2019.
The project was designed to address current and future population growth in Auckland and was the largest single-site
capital works delivery of wastewater infrastructure in New Zealand since Project Manukau was completed in 2000.
CH2M Beca was engaged for the life of this complex multi-disciplinary project from concept through to construction
management and commissioning.
An international team was engaged from June 2013 to September 2014 and delivered more than 40,000 hours of design and
procurement work in four countries. The construction phase, from October 2013 to October 2017, involved over 2,500 staff
and more than a million hours on site. The commissioning phase was completed in March 2018 after six months of testing.
To accommodate the upgrade of the plant, land to the south of Island Road was redeveloped, a 2km section of Watercare
Coastal Walkway was relocated as part of the Te Aroroa Trail, and a new 530-metre road was built to replace the eastern
section of Island Road. This new road provides access to the public areas of Puketutu Island, public walkways and the
coastal walkway.
Paul Evans, ACENZ CEO said “CH2M Beca maintained a collaborative and productive relationship with the client throughout. With thousands of hours of
design work from multiple disciplines and international expertise, their high-quality management and excellent
consulting service was the hallmark of success for this project.”
Design and consultation for the Watercare Mangere Wastewater Treatment Plant BNR Upgrade was carried out by CH2M Beca
for the client, Watercare.
