1) Drain the pool first, then use a wooden ladder.
2) Use scaffolding?
3) Use a cordless drill.
I'd go with option #1 and add #3. Best comromise - Cheaper than a scaffolding but no danger of falling into the water.
God forbid that guy would slip off that ladder and land in the pool with his electric drill.
P.S.: What's with all the bottles of booze? Where was this picture shot? Looks like at some resort or hotel...
