We operate our stormwater network under resource consents granted by Environment Canterbury, so we are responsible for elevated contamination in our rivers and streams.

If you are planning a building or development that uses our stormwater network, we suggest you get advice on stormwater and your property(external link) early to take this into account in the design and consenting process.

Once operational, certain occupiers are required to obtain a stormwater discharge licence. Your site may be audited and sampled to ensure that it is operating with adequate controls and good management practices in place to mitigate risks to our waterways.
