An overview of our stormwater system

When it rains, water flows down drains, picking up leaves, dirt, rubbish, and oil—this is called stormwater. Stormwater is one of the three waters, along with wastewater (from sewage) and freshwater (the lakes and rivers we drink from). 

Our local stormwater travels into our wetlands, where it's naturally filtered. Wetland plants can absorb some harmful chemicals, while soil breaks down pollutants with the help of bacteria. As the water moves through the wetlands, pollutants are trapped or broken down before reaching rivers or the ocean.

So next time, think about what you pour down the drain, remember—it could harm the wetlands and the plants and animals that clean our water.

What we’re doing to support a healthy stormwater system

Our work is improving the quality of water flowing into Puahuru (the confluence of the Kawerau and Shotover rivers)
