Sub-Station Flood Defences – Wymering, Porchester, Romsey & Bevois Valley

– Installation of concrete bunded areas around substation doors (if access was required during a flood an independent sump with a pump float and a non-return valve was installed to stop any water egressing into access point).

– Installation of heavy duty security and flood rated doors (where access was not an issue)

– Cable troughs were filled with either concrete, masonry, or steel

– Installation of approved duct sealing system into cable troughs

– All masonry checked and repaired so there were no weak areas for water to get into the cavity

– All weep holes, vents etc were raised above the flood level

– All outlet pipes, foul, surface water, etc. were checked for airtightness, repaired if required, and non-return valves set

– Roof and guttering repairs where required

– Pumps set in substation basements with the outlet above the high flood level externally
