East Cambridgeshire – Detailed WCS
adequate to avoid significant deterioration of P loadings in the Ouse Washes (i.e. not compromise the
achievement of a 0.33 mg/l P loading as per the target set by the EA RoC or the 0.1 mg/l P loading
normally used under JNCC Common Standards Monitoring guidance, if considered more appropriate).
Natural England have also requested the following additional studies:
• Detailed studies to evaluate the impacts of increased discharges on wider biodiversity;
• Water quality effects associated with discharges from Burwell and Bottisham WwTW on
the Cam Washes SSSI;
• Potential cumulative impacts (flood risk) of increased discharge from Burwell WwTW on
Wicken Fen;
• Potential cumulative flood risk impacts of Witcham, Witchford, Little Downham and
Littleport WwTWs on the Ouse Washes.
The conclusions of the ecological assessments contained within this Detailed WCS will need to be reexamined
in more detail as part of any applications to increase the discharge consents for relevant
WwTWs or planning applications associated with WwTW extensions to confirm their validity.
