We operate our stormwater network under resource consents granted by Environment Canterbury (ECan)(external link), so we are responsible for elevated contamination in our rivers and streams.
If you are planning a building or development that would use our stormwater network, we suggest you get advice on stormwater and your property early to take this into account in the design and consenting process.
If you have an existing industrial site, you may be audited to ensure that your site is operating with adequate controls and good management practices in place to mitigate your risks to our waterways.
If no unavoidable and/or unacceptable risks to stormwater are found, your site will be issued an approval to continue discharging stormwater. If we suspect elevated contaminants in your stormwater discharge, we may collect samples and/or issue you a list of action items to reduce your risk.
