Graham Road stormwater upgrade

Building resilience for Inner Kaiti

We’re upgrading the stormwater network on Graham Road to help reduce flooding during heavy rain - protecting nearby homes, schools and public spaces in Inner Kaiti.

This project will boost the capacity of the stormwater system and futureproof the network for local needs.

The stormwater system on Graham Road has been identified as under-capacity, meaning it struggles to cope with heavy rain. This has led to localised flooding of streets, public spaces and properties. Upgrading the network will:

  • Provide better flood protection for homes, schools, and public spaces
  • Improve safety and resilience for the community
  • Reduce the impact of severe weather events in the future
  • Enable more public drains on private properties in future, especially where floodwater risks entering gully traps, which can overwhelm the wastewater system and cause overflows into rivers
Construction in 3 stages and is now expected to be completed by late June 2026

What we're doing

We're replacing existing pipes with bigger ones to increase capacity. Installing new sumps and manholes while working carefully around utilities such as water, power and internet.

Through the duration of the work, Graham Road residents will have access to their properties and driveways at all times.
