Queenstown - NZ

 

THE CHALLENGE

The Queenstown Lakes District lies in the Otago Region in the South Island. The Queenstown Lakes District Council is responsible for providing a safe supply of water to the popular Queenstown and Wanaka area, for a population that can double in peak tourist season.
Veolia is contracted to continue to improve of the quality and reliability of the Council’s water assets, while achieving consistent operations and maintenance requirements.
 

THE SOLUTION

Veolia was originally contracted to service the area in 2008, and through a combination of proven asset management improvements and competitive best practices, the contract was extended in 2015 with a further mandate to improve.
Veolia’s works identify and improve the water, wastewater and stormwater network in the district, guided by an overarching programme that cost-effectively ensures that assets are accurately monitored and reported on.
Veolia provides maintenance services necessary to support:
  • 402 kilometres of water mains
  • 295 kilometres of stormwater mains
  • 362 kilometres of wastewater mains
  • 11 water treatment plants
  • 2 wastewater treatment plants
  • 67 pumping stations across the water and wastewater network
  • 20 reservoirs.  

To effectively manage these assets and ensure consistent high quality service during peak holiday periods, Veolia developed strict SCADA and electrical standards for plant upgrades, as well as a more efficient SCADA programme for the peak periods.

Veolia have also introduced a number of improvements since contract commencement such as:
  • Creating a capital infrastructure works team
  • Installation of flow monitoring systems
  • Upgrading chlorine controls
  • Improved wastewater flow analysis reporting
  • Implementing reliability focused maintenance analysis
  • Installing CCTV drainage monitoring.
 

THE RESULT

  • Competitive lump sum and unit rate pricing arrangement which has minimised cost and maximised value to the Queenstown Lakes community.
  • Standardised processes that ensure streamlined and efficient capital works upgrades.
  • Accurate documentation and recording of all operations and maintenance data for capital assets, creating reduced service requests even as population increases.
  • Detailed SCADA programmes ensure efficient electricity costs and financial savings even during peak load periods.
  • Qualified personnel using best practice and network management procedures have safeguarded public health and ensured compliance with all New Zealand drinking water standards.
