One gallon of water weights 8.35 lbs.
That pool has a capacity of 5,455 gallons.
That’s 45,000 lbs or 22.5 tons of water.
That’s about the same as 8 Ford Expeditions.
Whatever you put it on, make sure it is designed for carrying that much weight, or at least is evenly supportive so it doesn’t sink more on one side than another.
Also, splashing occurs so water from the pool can soften the ground under the pool. Make sure it isn’t too close to a sloped hillside.
