Answer 1

Depending on the size that you are wanting. I would first lay out the overall dimensions of the pit with marker paint. Then I would have the local utilities come a check for any buried lines that you might encounter, After all that is complete. dig your pit a foot deeper than your requiring, I would place a layer of chat rock down and then cover with sand, place a rubber liner into the pit covering the floor of the pit and the sides, with this in mind I would make small holes in the liner so that any water that entered the pit would drain down into the sand and gravel under the liner. make sure the liner extends over the top of the pit far enough that you can secure the liner along the top around the pit.
