The Annex 14 Recommendation is a 240 metre RESA. If this cannot be obtained, which SOU cannot ever do due to the railyard and the M27, a safety case will be necessary to either show that there is reasonable chance that aircraft using the runway can be contained within something less, or the likelihood of an overrun is reduced due to other mitigation, often runway surface friction characteristics, which inevitably comes back to having excellent drainage to reduce the risk of a "wet" runway (or worse).
As mention in many posts, grooving is the way to provide for optimum drainage. Unfortunately while SOU's runway is grooved, as I have in the past pointed out, its not draining as it should. Hopefully this is now being considered and something will be done to improve the 1960s vintage drainage system, which was installed when the runway was originally constructed.
Hopefully the relatively new SOU owners have done their homework, otherwise we could possibly be back into the eggy face mode, which was unfortunately all too frequent an event in the days of Bl***y Awful Airports plc ownership.
Drainage works happening on the far side of the airfield going by yesterday's You Tube clip of the returning EZY service, maybe linked?
