We cleaned out a couple of hog confinement pits a couple of weeks ago--------took out a lot of slurry at the very bottom......ie got into a lot of sediment.

Seems that we ought to be stirring the slurry a little more than we were---------we were using one pump at one location at one end of the building.

It did not seem to me that the "backwash" from that one pump was enough to adquately stir a 2500-head building, so that the bottom sediment was getting mixed enough.

One fellow said that he used another pump at the end of a building this size to just stir..........and let it run all the time during the removal operations.

What are your experiences??

Would running a second pump, merely for agitation, but slow enough to not cause foam so the hogs aren't gassed-------be enough to get the bulk of the sediment into solution?

 Do we need to get creative, and say, lay plastic field tile in the bottom of the pits from a central manifold so that several areas get some agitation action at the same time?

Thanks.
