Does any one know what the maximum recommended fall is on fowl drainage (solids) as im lead to believe there is one, and exceeding it may cause problems. Thanx.

1:40 is optimum,this works out at about 25mm per metre
our local BC prefer you to tumble a section rather than have say 1:20 as this causes separation ,which isnt good
up to 1:100 can be used for surface water
