Why are we considering delivering wastewater services differently?

The management and operation of Council’s wastewater network infrastructure is becoming increasingly complex. Demands and risks on wastewater networks is a significant concern for all of New Zealand and nationally the management and delivery of wastewater services is under the microscope.

We have some major challenges ahead of us:

  1. Ageing network
  2. Growth
  3. Compliance
  4. Out of Forest commitment
  5. Capability - Future skill shortage in workforce
  6. Climate change
  7. Funding and financing of the services
  8. Central government - localism vs amalgamation and regulation of service and delivery

The proposal

Contract for service delivery spanning 25 years – This reflects the long lifecycles of networks and links all network systems under one comprehensive set of performance objectives.

Operate-Maintain-Renew

The contractor will be responsible for:

  • All operations to maintain networks in stable and reliable condition
  • Deliver required level of service
  • Comply with all resource consent measures

Design-Build-Operate-Maintain-Renew

The upgraded wastewater treatment plant in accordance with resource consent conditions (when known)

What has been undertaken to date?

This has been a three-stage process:

  • Expressions of Interest form suitably qualified groups/consortia/companies
  • Request for tender and shortlisting following extensive testing, interviews and reference checking
  • Preferred consortia presented to Council
  • Ongoing work with consortia to develop viable and prudent proposal
  • Proposal supported in principle by Council subject to community feedback and peer review of all aspects of the contract.
