Run your power circuit this year while the ground is warm & easy to dig.
I used a 1" conduit & pulled #10 AWG copper for a 20A circuit. Make sure to install a switch before the pump so you can quickly turn it off if needed.
I mounted the switch on the house, then ran the conduit out the bottom to the plug by the pool.
Drive a couple of ground rods & make sure to ground the metal parts of the pool to the rods. The life you save might be your own.
Make sure to install a correct brand GFIC breaker in your panel to feed the pool. Do not install anything else on the circuit, or tap into an existing circuit.
Do it right or don't bother.
Do not cheap out & run #14 AWG wire, because it will just pop the breaker all the time. Make sure you get a sand filter for it. You will probably get a cheapy 1/2 hp pump with it, which will work, but isn't enough to change the water frequently.
I upped my pump to a 1 HP pump, and the water clarity issues cleared up overnight with the larger pump.
While you're already digging, install a 2" PVC drain line so when you back flush the filter, you aren't dumping chlorinated water on your lawn.
Run it to someplace unobjectionable so the water won't ruin your lawn.
The pool kit will come with the siding material in the kit. Make sure to buy a solar cover, and a really good winter cover. Buy the float pillows for the winter cover when you buy the pool so you don't have to run out at the end of the season trying to buy some only to find out nobody has them in stock.
That should keep you busy for the rest of this summer anyway.
