In the Kāpiti District, the network consists of approximately 210 km of pipes as well as a vast open channel and stream network. Within urban parts of the district, the open channels and streams are typically constrained by surrounding land uses and so require ongoing maintenance to mitigate flood and erosion risk to surrounding properties.

Works in the Kāpiti District Stream and Open Channel Network, which includes:

•Contract and information management

•Inspection activities

•Hand or machine clearance of vegetation, sediment and or gravel at specific streams (including stream mouth cutting), open channels, culverts, stormwater inlet and outlet points including grills and grates

•Inspection point, flood gate cleaning

•Heavy rain/emergency cleaning

•Responding to open channel and stream network concerns raised by local residents and stakeholders as service requests.

•Stream and open channel maintenance

•Vegetation maintenance

•Miscellaneous improvements, as instructed.
