Forgot to add, the above info is assuming the whole 4000 gals is in the ground.

4000 gal is approx 18,180 litres, 1000 litres to a cubic metre, therefore 18.18 cubic metres, but that would be for perfectly compacted ground with no air holes, voids etc, I would suggest that you start with around 12 cube and compact in layers of around 250 - 300mm (10" - 12") to avoid t...

Just a few comments that may help. I can't tell from the photo but I assume that your neighbours garden is level with yours, if so, you should ask him the last time he saw water running up hill ??
