One point not mentioned, is the sand also blocks roadside drains causing flooding, I have complained for years, but they only clear them when they flood, bearing in mind the recent story..........
from 20/9/23 A message on the FOWS FB page............
the torrential rain last night and this morning has resulted in an unpleasant overflow of contaminated water on the area by the boating lake and in the lake (use your imagination) and I suggest not allowing children, dogs etc. to stray into that area. Welsh Water have been quick to arrive on scene and appear to be dealing with it now
