The stormwater system is designed to contain, channel and pipe rainfall and natural water run off into rivers and sea. It is untreated and separate from the wastewater/ sewage system.
Council manages its stormwater activities across the district under 16 Urban Drainage Areas (UDAs) and one General Drainage Area (GDA).

Preventing Stormwater Pollution
Yellow Stormwater Fish
Most stormwater grates have a yellow fish painted beside them to remind people that stormwater grates drain straight to rivers and the sea. The stormwater system should drain only rain, not waste.
Keep it Clean
Keep it Clean is the latest booklet to be released by Water NZ and offers tips and ideas on preventing stormwater pollution. This booklet is essential reading for all those Kiwi "D.I.Y'ers" wanting simple and practical advice on carrying out home handiwork, such as painting, water-blasting and car maintenance, without impacting on local streams, rivers and other waterways.
