We’re always maintaining and improving our stormwater system to help make the city a safer and healthier place to live.

The network includes open drains, pipes, pump stations, stopbanks and detention basins. We also need to comply with regulatory requirements.

We propose spending $912 million on infrastructure over the next 10 years, including:

  • Flood and stormwater priority works (Ōtākaro Avon River Corridor) – $137 million
  • Waterway lining renewal programme – $90 million
  • Reticulation renewal programme – $42 million
  • Ōtākaro Avon waterway detention and treatment facilities – $42 million
  • Pūharakekenui Styx waterway detention and treatment facilities programme – $106 million
  • Improving water quality in our urban waterways through initiatives such as more management of pest plants in the Ōpāwaho Heathcote River, and a District Plan change to protect the Ōpāwaho Heathcote River as a site of ecological significance – $22 million
  • Establishing a programme to resolve regular surface flooding – $183 million (starting in 2027)
