Thanks for that Scott, hopefully when you get out to LI next week you will see my situation is not going to allow any draining to that degree.
Water disposal around here is a big deal, we dont have sewers and the ground is such a hard clay the drainage is very minimal. The law here reads that each resident is responsable for thier water drainage and that it can not be pumped into any street basin. The former owners here were fined twice for just trying to lower the pond level after a heavy rain week.
Whatever needs to be done here will be an idea outside the box, maybe not a perfect solution but something better than I have now. Instead of my dumpster idea, how about a cesspool truck which is enclosed so no smell and can handle silt with its pump, the trucks can hold 5000 gallons. I know it would also suckup alot of water but maybe 1 or 2 loads dragging the vacuum hose across the bottom a few times could get a decent amount of the silt out?
