Sure you can do that, for safety( and it is really easy ). But I think the larger goal here is to develop methods for filtration; it doesn't use electricity, machinery and uses local water.

I think this is the best example of what a project on kickstarter is supposed to be.

You'd still need chlorine to keep the swimmers' bodies from fouling up the water, unless you're substantially refilling continuously.
