Earlier today user made a thread asking why the Mariner doesn't just purify sea water instead of urine to produce potable water.
In the extended Ulysses Cut edition, this question is both asked and answered directly. Here we see Enola (the little girl) and Helen (the woman) having collected their urine in cups. Helen asks the Mariner (Kevin Costner) why he doesn't use sea water. His response: seawater is harder on the filters. In the next shot, he combines their urine, runs it through the filter, and then drinks it.
why do people hate water world? i use to watch it all the time and enjoy it. it's a classic

The best thing about Cable Guy is when Jim Carrys character says that Waterworld is misunderstood and that he's seen it 9 times

>seawater is harder on the filters. In the next shot, he combines their urine, runs it through the filter, and then drinks it Sounds like he's just making excuses for his piss-drinking fetish
