Every year, millions of litres of stormwater is discharged into the city’s streams, harbour and coastal waters.
That stormwater can contain contaminants, such as oils, paints, detergents, litter, animal droppings, and – after heavy rainfall – sewage. The environmental impacts of stormwater runoff are monitored, and generally comply with resource consents and environmental standards.
In the next three years, we will be introducing real-time monitoring of the stormwater network. This will enable us to measure flows of stormwater and pollutants into waterways, and allow us to better manage pollutants when stormwater is causing environmental harm.
