Flood protection and drainage schemes

ORC manages flood protection and drainage infrastructure in the following areas: 

  • Alexandra 
  • Water of Leith 
  • Lower Clutha 
  • Lower, East and West Taieri 
  • Shotover Delta 
  • Tokomairiro 
  • Lower Waitaki


Sea level rise may cause increasing flooding and drainage risks, especially in the Taieri and Lower Clutha areas. This is because they are flood plains, where large parts of the land are less than a metre above sea level. 

The Climate Resilience Programme is currently partially funding our works to get these flood and drainage schemes up to standards to accommodate for climate change. 

As a part of the works, we consult with communities benefiting from flood protection and drainage schemes to ensure their level of service remains appropriate (apart from the Leith flood protection scheme, which is in the final stage of being upgraded).
