Kawerau’s stormwater system is a 30 kilometre network of pipes, manholes and cesspits which collects stormwater from roads and transports it to the Tarawera River either directly, or via the Ruruanga Stream and the Overflow Stream, which are tributaries. 

The activity involves:

• Collection and removal of stormwater 
• Repairing or replacing unsound pipes and other stormwater structures
• Cleaning and unblocking gutters, cesspits and pipes.
