Reference is made to groundwater sources utilised for potable (clean) water to supply Anglian Water's customers.

There are a number of sources and SPZs close to proposed developments:
• Aylsham - Aylsham and Coldham Hall sources
• Cawston – Salle Bridge
• Norwich – Costessey Pits,Marlingford, Bowthorpe, Colney, Thorpe St Andrew, Trowse Newton, Caistor St Edmund, Postwick
• Wicklewood – High Oak
• Kirby Cane – Kirby Cane

However there is no policy to ensure that development proposals explicitly give full consideration to the risk of pollution to groundwater sources as set above. Including the documentation to be provided at application stage including mitigation where required.
