Does anyone know the name of this tv show?

i watched it last year and it was kinda like a reality show where
strangers had to live in an abandoned town and try to survive with no
outside help.

there was an episode where the were eating a pig that was already dead
with bugs and stuff on it. there was also a part where this girl
wasted water to shampoo her hair and everyone got mad at her. And
there was also a part where this guy cut himself on a rusty nail or
something and was scared of getting an infection...don't know if any
of that helped...

im not sure what channel it was on, something on cable.

does anyone know the name of this show?
thankss
