The project is one of a series being developed to cater for the anticipated population growth on Auckland鈥檚 North Shore.
Watercare is the local government-owned organisation that owns and operates Auckland鈥檚 water and wastewater infrastructure. The expansion of Rosedale includes a new 3km pipeline and pump station, an additional primary sedimentation tank, digester and feed tank system and a modified Ludzack Ettinger reactor to treat wastewater. A visitor centre and administration complex will also be constructed.
鈥淢ott MacDonald has provided professional and monitoring services to Watercare on many of its water and wastewater treatment plants and pipelines,鈥� said Steve Couper, Mott MacDonald鈥檚 water practice leader for Australasia. 鈥淲e are also part of the team looking at option development and concept design for a major combined interceptor from Auckland鈥檚 outer western catchment direct to the Rosedale plant, known as the Northern Interceptor project.鈥�
Mott MacDonald acquired AWT, a specialist water technology and consulting company based in New Zealand and Australia in April. The acquisition was a key part of the consultancy鈥檚 business strategy to broaden the services it offers in the Australasia region.
The Rosedale expansion is due to be completed in 2019.
