Problem with water pressure

My aunt and her family who lives in the province couldn't have water in their house.Normally there's already a water line but since they live in a higher place,the pressure is not enough for the water to go up.Some of their neighbours already have some commercial pumps and are having water in their houses.They don't have a choice but to buy a pump.It will be very convenient for them to have it.

Here in France,they have what you call a "chateau d'eau" where it helps to provide water pressure to elevated places.We are living on the top of the hill but we don't have any water pressure problem.
