I have lived in Lima quite a few years and always experienced low water pressure. We moved in to our home ten years ago, had problems with the water supply and therefor installed a subterranean tank and pumps. This gave us high water pressure throughout our home. I monitored the usage and found there was no change what so ever in usage and cost.

The tanks on top of houses is just a water reservoir, not for increasing water pressure. Some districts with some advantage because of its lower location as Magdalena, San Miguel, etc. in Lima, have better water pressure than others districts located at slight higher altitude as La Molina, etc. It is a universal physical law, as you know.
So in the case of district that cannot get enough water pressure (measured in pounds-per-square inch PSI ) it is necessary to keep a water reservoir at the first floor and then to pump it up using an electric pump or directly using a water pressure system "sistema de agua presurizado" or using both methods at the same
In the past, Magdalena also had water flow problem. Some months ago, there was a replacement of the main water pipeline (“tubería matriz”) and now we have both a natural pressure and an improved water flow
Here at home with only a 1,100 liters black water reservoir is enough. No need for additional water tank at the first floor and no need for “sistema de agua presurizado”
Don’t you think I am a lucky guy ?
