When I lived in northern virginia near DC, my neighbor wanted to give his two kids a pool so he went and bought one just like the one you posted. His backyard was all grass and not entirely level so when he filled it the first time, it didnt fill level and kept spilling water out. He drained it and then decided to level his yard. He used dirt to level his yard and basically tossed dirt on his lawn until it was to a point where he thought it was level. I recommended a 2×4 platform but he thought the dirt was sufficient. He also barbecued in the middle of his yard instead of on the deck attached to the house. I asked him why and he said he once had an accident with the grill so he didnt want to burn his house down.
