Christchurch's waterways have drainage, ecological, recreational, cultural, heritage and amenity values.
As Christchurch is a very flat area, extended or heavy rainfall can cause parts of the city to flood.
Our stormwater system is being continually maintained and improved to make the city a safer and healthier place to live. The network includes open drains, pipes, pump stations, stopbanks and detention basins, as well as other structures such as the Woolston barrier on the Heathcote River.
Christchurch City Council manages flood capacity within the city's rivers and their tributaries.
