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.

The Improving Urban Waterway Health programme (formerly known as River Guardians) aims to improve the health of Christchurch's rivers and streams.
The goal is for Environment Canterbury, the Christchurch City Council and the community to work together to get involved and create healthier waterways for Christchurch residents.
Research is well underway to establish what is affecting the health of these waterways and what might be done to improve the quality of them, but rather than wait for results, there's things we can do now at home, at work, at school and at play, that can help achieve this goal.
