This piglet was having a grand time in the mud next to the outhouse I was using in the Sacred Valley in Peru. The ground you see surrounding the piglet is pretty similar to what I saw inside the outhouse, except that the outhouse has a hole dug into the dirt. I have pretty decent balance, which is a good thing. You certainly wouldn't want to slip and end up with a foot in the hole.
Many Peruvians are upgrading their pit latrines to flush latrine. Instead of a dirt hole, there is a tile with a hole in it. The tile hole leads to a pipeline that's up to 5 meters long and ends in a sanitary pit. This set up is sort of a long-distance outhouse that keeps the smells and insects at bay. You might think that a flush latrine has running water piped in like we do in the US. That's not necessarily the case. One of the flush latrines that I used had a bucket of water for manually flushing.
The big advantage over flush latrines from the one I used next to the friendly piglet, is that having water available for flushing means you also have water available for hand washing. Clean hands prevent disease!
