Small pool over septic tank?

We have one of these 'Easy Set' 12' x 38" round swimming pools that you blow up the ring and fill with water. It seems the only really level place in our yard is over the septic tank. I don't know how much weight is safe to put over the tank. Any thoughts?

A picture of the pool can be found here:

Your talking almost 11 tons of weight for that pool, no way should it go over a septic tank!

Pool volume:

Water weighs just under 8.4 pounds per gallon.

Walmart says your pool holds just under18 hundred gallons of water when it is 80 percent full.

That is 15 thousand pounds.

The diameter of your pool is 12 feet, making the surface area 113.1 s.f. approx.

The weight of the pool is approx. 132.6 pounds per s.f. or just under

What weight will your septic tank bear?

I would not do this, but check the local code. In my area you cannot even drive or even park on a septic/leech field.

I wouldn't do it.. over the tank OR the field..all in all... I think it's a s***ty idea.. pun intended.. Chuck (in SC)

Ug. Walmart.

I'll leave the weight consideration for others.

Have you considered what you will have to do when you get the tank pumped?

Its a temporary setup of course.. but i may go ahead and move it based on the recommendations above. Certainly I dont want to take a chance. As for the weight, it is alot, but you can easily place your arm up underneath the pool without issue, even filled, so it does disperse the weight. But no point in chancing it, so Ill move it. Thanks for the input.

When in doubt.............

Since you're on septic, you might consider where exactly all that water will go when it comes time to drain it. As a general consideration I don't put any water near or around my tank, drain field, or any locations upstream. But I live in the PNW, watering the lawn is rarely required.

Good point.

"Around here" new installations have interceptors above the actual drain field. The interceptors take water dumped above the drain field and take it below the drain field. But usually the drain field isn't immediately adjacent to the tank. In any case, he can run his pool draining hose to below his septic field.

Remember the 70s book, "The Grass is Always Greener over the Septic Field?"
