In a typical house or apartment block there is a cistern. This is a large tank that stores water locally for the building or home.

Dude, I don't know where or what time you're living in but in all the construction, New and remodel out here in california I've never run into one of these. All the water for the entre house comes in through the mains. The only time I've seen any sort of Cistern thing you're descibing in is at a farm with a water tower. This however was filled from the main, and it was sealed. This acted as the pressure source for the property. All the drains are piped to the central main, one pipe in one pipe out.
