Stormwater is rain. The purpose of the stormwater system is to prevent flooding and provide a safe way for the rainwater to drain away from populated areas.
Stormwater that runs off properties, roads and footpaths goes straight into the city’s stormwater system. This ends up in the Tauranga harbour untreated, which means it’s important that stormwater is as clean as possible.
Tauranga’s stormwater network includes over 460km of stormwater pipes, 9800 manholes, 75km of open drains and more than 800 outlets that deliver stormwater into the harbour, rivers and ocean.
