A 3" semi trash pump will move a lot of water. I disconnected the fuel tank that came with mine, and used a 6 gal steel outboard motor fuel tank. Brazed a fitting at the bottom, set it on a bucket and connect it to the fuel line on the pump. It will run for 18 hrs at WOT, well over 24 hr at part throttle. At WOT the pump is rated for just under 14,000 gph. If you neck up the outlet to 4" right after the pump it will move more than that.

Set the pump as close to the water level as possible and let the pump push the water.

I use a strainer on the intake side, but the best way to stop all the crud from plugging up the screen is to float the intake under a truck inner tube. I put the suction line and strainer thru the center of the tube and have it just deep enough so it doesn't make a vortex and suck air. I will stake the innertube in place, or it will want to move to shore....
