Would you be able to survive without plumbing, electricity, or Wi-Fi?

I could survive without electricity or Wi-Fi, but not without plumbing. Our basic need is at least a sink with running water, and you'd need gas too to make your food. But then if I'd say I can live without Wi-Fi, this society is so much based on electricity and Wi-Fi, if you have to look something up in a library you just are most likely not going to find whatever you need... while the internet is so easy to search for answers, about anything.
