2.1.10 Flood Protection, Water Supply and Sewage Assets

Environment Agency owned and operated assets

During the winter the Devon & Cornwall Asset Performance and MEICA teams carried out several post
event asset inspections to monitor the integrity of the flood defences. The prolonged nationwide event
also prompted the Agency to request military assistance.

Though the storms were focused on the coast, some fluvial assets were also affected by high river
flows and tidal assets by repeated loading. The list below details the assets that were identified as
being affected. Some of these assets are owned by a third party but the Environment Agency took an
active role in assisting with the repair using its  discretionary powers.

  • Flood Bank on the Par river
  • Copperhouse (Hayle) tidal gate
  • Padstow tidal gate
  • Polperro tidal gate
  • Bude Flood Alleviation Scheme raised defences
  • Helston Flood Alleviation Scheme & Loe Bar outlet culvert and associated structures.
  • Mawgan Porth fluvial defences
  • Lower Tamar embankments, including Calstock flood bank
  • Raised defences at Angarrack

In addition to the affected flood defences several watercourses have received extra sediment leading to
restrictions in conveyance at some locations. Plans to dredge these particular areas and recover the
affected assets are underway.
