Can you please elaborate on your edits here? What is this ditch that flows uphill and connects to trenches https://www.openstreetmap.org/way/1423368941 ? Why are there ditch culvert between trenches like https://www.openstreetmap.org/way/1423368945 , what is here under the tracks and road ? Some of trenches you drew literally cross a highway like https://www.openstreetmap.org/way/1423368926 . 

Please fix these features.
