In our modern world, we have a pretty good idea of where our water comes from, so in Modern settings this is not something that needs any thought. BUT when it comes to fantasy, historical, and sci-fi settings - this can be a useful detail to know! For this exercise, you need to jot down how plumbing or running water works for your location. IN A FANTASY SETTING: - Is your civilization advanced enough to have running water? - Is there pipes and plumbing? - Does it run on magic or technology? - Where does the water come from? - What is the water quality? IN A SCIFI SETTING: - Is this a world or location with advanced technology? - Is this a space station or ship? - Where is the water stored? - How does the water get cleaned or recycled? - Where does the water come from? There are probably lots of other details you can add in, feel free to get creative or unique!
