Don't know but I will be moving the pump to the birm on the highway side momentarily which will have the out take hose level and them dropping to the ditch.
Here's a couple of photos showing how much the out take hose has to go uphill and is obviously putting pressure on the pump.
I have always heard what esshup has said. It's better to have the pump as close to the water with a short intake hose. Its easier to push than pull.
I assume that by putting the pump at the berm you will have to add more suction hose AND it will have to pull it higher, but with a shorter outflow hose? This will be an interesting on-hand experiment to see if it gets better or worse.
And as a lot of said so far, thanks for the very detailed process you are going thru. Very interesting and much appreciated.
