Some parts of Norfolk are at risk of nutrient pollution. You can view maps showing the affected catchment areas, including:
- The Broads catchment area map for Special Areas of Conservation and Ramsar Site
- River Wensum catchment area map for Special Areas of Conservation
- Norfolk catchment map
- Nutrients catchment map (overview)
- Wensum nutrient catchment map
- Yare nutrient catchment map
- Bure nutrient catchment map
These maps also show which areas are served by wastewater treatment works (WwTWs).
Important Notes:
- Map data may not be fully accurate. Please contact Anglian Water for confirmation.
- If your site drains to a WwTW within the catchment, complete Stages 1–3 of the calculator.
- If your site is outside the catchment but connects to a WwTW inside it, skip Stages 2 and 3.
- If your site drains to a WwTW outside the catchment, mitigation is not required.
