Plumber here. Unless we're talking about sky scrapers the grid pressure is generally enough to lift the water to the top floors. As long as it's lower than the city water tower there's no issue. If it's a flat terrain or the building is on a hill then yes, you might need a pump to boost the pressure. Sewage on the other hand is not an issue - gravity takes care of that.

Finally, "shit-ton" would be a legit word. "This high rise produces 8 shit-tons of energy per month!"

(...considering when fuck-ton will have its day as well..)

I guess you could but probably wouldn't be worth the cost of such system.
