All the stormwater from Christchurch City's roofs, roads, driveways and parks, flows down 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, Heathcote, 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 Cleanwaterways project's goal is for Environment Canterbury, the Christchurch City Council and the community to work together and create healthier waterways for Christchurch residents.
