Project Milestones:

  • Reverse briefing, solution development and presentation
  • Advanced electrical system design combining PLC, VSD and SCADA systems to create a total solution
  • Installation of all electrical services
  • Extensive pre-deployment testing

Project overview:

The Ashburton District Council provides wastewater services to more than 7000 properties. With projected population growth on the horizon, the Council decided it was time to rethink the wastewater system and implement a more environmentally sound solution.

Overseen by the project management team at Downer, Millennium was engaged to design and implement all the electrical systems. The resulting solution uses a sequential series of sediment ponds and pumps to break down waste and purify the water. At the end of the process, the outflow is used to irrigate local pastures. This advance eco-friendly system is heavily reliant on control management and automation to work efficiently. The scope-of-work presented many unique challenges including enabling the control hardware and software to manage the sequential logic onwhich the system functions. Much of this system required custom programming and integration of all components — both new and pre-existing.

Millennium also designed and enabled a remote log in control and monitoring system for use by the Ashburton District Council staff and their sub-contractors, plus undertook a significant volume of pre-deployment testing to ensure the end solution meet the Council’s requirements.

The end result —the Ashburton District now has one of the most innovative and eco-friendly wastewater systems in the country.
