Hail,
Dont know exactly but I always put in 100mm poly ag pipe with the holes in it and backfill with bluemetal to just below the top.
Perforated pipe at the bottom as mentioned. Backfill should create a vertical drainage "blanket" of rock about 100mm thick, separated from the rest of the backfill (any material, more or less) by a sheet of filter cloth. Build up in thin layers of each for ease of construction.
