As far as I know, no one gargles with pool water, or at least no one should. Gross.
usually do get the feel of water like the smell, the temperature, or even some swimmers taste the water. The smell so you know what it is going to be like when you get in. Some pools smell different than others. The temperature to not be shocked when you dive in and the taste just in case you get some in your mouth it won't be a shock too.
There were 900 pool swimmers, and 50 open water swimmers.
A pool or water area, swimmers, a towel
The water has chlorine in it to kill bacteria and viruses, so they are really tasting the chlorine, not the water.
If it is just rain, you stay on your tower and guard the swimmers. If there is thunder & lightning, you clear the pool and wait 20 minutes from the last display of thunder & lightning before letting the swimmers back in the water. It is best if the swimmers are not standing on a wet pool deck while waiting for the all-clear to re-enter the pool.

It just depends of the strictness of your pool. Most place will allow them. Just be sure not to disturb other swimmers with them.
The dept of the swimming pool dosnt matter because the swimmers dont touch the bottom at all.
Yes. The water will evaporate, leaving the salt behind. Let the process go on long enough, and you'll have a brine pool of VERY salty water. The only way that salt gets out of the pool is when swimmers track the salt water away as they walk away.
A pool filter is there to remove particles of foreign matter from the pools water. Without a filter to remove this material it would not take long for the pools water to become cloudy and dangerous to the health of the swimmers.
to calm down
The names of the swimmers are only shown on the TV screen, not actually projected on to the water.
