Anyone know how much fall to put on concrete stable floor so urine runs?

[Beaner]

We are planning some new stables, with the floors slighly sloping to the back of the stable do urine runs out and away, anyone any idea how much fall to put - I have read different amounts from 0.5" to 3" over a 12ft stable. Also the outside needs to have a fall on it so the rain runs away again wany idea how much?? Thank you x

The figure 1" in 80" comes to mind, but I have no idea where I got that from so I wouldn't take that as gospel.

An 'alleged' 1" over 15', which we were assured was plenty, isn't!
