Stormwater
We deliver resilient and future proof stormwater infrastructure to manage rain and surface water urban and suburban to prevent flooding, reduce erosion, and protect water quality. We have a strong background in storm/wastewater separation projects which improve the water quality of our streams, beaches and waterways by reducing the volume of stormwater running into the wastewater network to mitigate the chances of overflows. Each project we complete we have increased the capacity of the network which enables more homes to be built and our communities to remain safeguarded from events like the Auckland and Hawkes Bay flood events of 2023. We have significant experience in the delivery of:
- Pipeline installation
- Flood remediation works
- Upgrade and renewals programmes
- Outflows
- Stream works
