"In fact, Michael, urine is essentially sterile so there isn't actually anything to kill in the first place," biochemist Stuart Jones wrote in SAS' Celebrity and Science 2012 review.
"Urine is largely just salts and water with moderate amounts of protein and DNA breakdown products. Chlorine just prevents bacteria from growing in the pool.
"So you're basically right - peeing in a swimming pool, even if all swimmers do it simultaneously, has very little impact on the composition of the pool water itself. An Olympic-size pool contains over two million litres of water and a single urination is somewhere in the region of 0.2 litres."
"To have any significant effect on the overall composition of the pool water you'd need a serious amount of peeing," concluded Jones.
So you have that going for you.
