I am planning to supply drinking water only (not bath or sanitation or washing) from a tank on a 10-storey building.
The problem is that if a gravity feed is used, then the pressure will be different on each floor. For example, the estimated PSI will be only 7 on the top floor and 46 on the bottom. Ideally we want to have a PSI of 40 PSI on every floor. How can this be accomplished?
