If we look after the waters and land around us, we will be looked after in turn.
At Work
All the stormwater from Christchurch City's roofs, roads, driveways, footpaths and carparks flows down gutters and drains into a series of underground pipes and open waterways, our stormwater network.
This water eventually flows into one of our City's rivers, the Avon River/Ōtākaro, Heathcote River/Ōpāwaho, Halswell and Styx Rivers, the Estuary and Brooklands Lagoon and eventually out to sea.
Most stormwater doesn't get treated at any point on its way to the rivers, so whatever goes down the drain generally goes into the rivers.
We all have a collective responsibility towards the health of Christchurch's waterways, so if you're already doing some of these tips listed below - great - as it's a step closer to our goal of healthier streams and rivers for Christchurch.
Environment Canterbury has a service to assist business to identify and resolve pollution issues.
