In rural areas without running water, how to drink clean water?

My hometown in the countryside, are drinking well water, when I was very young, is the home to build a well, and then is the water bucket water stretcher, the family pick water to drink! There are also people who buy the kind of water pressure, a hard pressure, out of the water. But sometimes it is not good to use, you need to put water into it before water can come out, but it is much better than picking water! After that, there is a water pump, install a good pump, electricity, the water pipe treatment, as long as the pull the gate again or press the switch, so that the pump is energized, the water from the well through the water pipe into the tank, so it is very convenient, in addition to electricity, are better, the family is also more relaxed, and a lot more convenient! Although these are not running water, they are also more convenient. In addition, the water quality problem, in fact, to be honest, when I was a child, water is also different, that is, there are springs, there is alkaline water, a village each home well water may be different, alkaline water is not good to drink, there was no way to do so before, and now a lot of homes installed water purifiers, so it is also a lot better!
