Master Tip #3 - Hydration
You are 61% water, so there are few things more important than finding more. Simply put you survive by a law of Threes:
You can survive 3 minute without air (luckily it’s plentiful). You can survive 3 hours without shelter in extreme environments (This is an important one in the wasteland). You can survive 3 days without water (it’s also nearly impossible to find it clean now). You can survive 3 weeks without food (if you make it 3 weeks you’re already lucky).
In most situations clean water is going to be the hardest to find. With the destruction of civilization water treatment plants are gone or non-functional; and most people aren't as well prepared for this as you. They’ll still feel the need to wash themselves in the rivers they drink from. Along with their ball sweat that river will be a soup of radioactive fallout, rotting zombie bodies, alien elements, and feces borne pathogens.
Needless to say it’s a good idea to find alternative sources of water, hopefully un-used and untainted by others. Watch out for surface runoff or anything that contains exposed runoff. Radioactive fallout will be washed and concentrated in these areas. Morning dew from the leaf of a plant would be nice but everything is a hellish dry wasteland and all the plants are stunted and dying.
Best place to get water is anything that was sealed up or stored underground. Water passing underground is naturally filtered and as long as it has been underground for more than 500ft and isn't drainage from a mass-grave or zombie filled city. Underground aquifers should be pretty well protected, the bombs may have vaporized surface water into the upper atmosphere but just a few feet down water would be protected. Aquifers are usually 20-50ft down and will be protected by that much soil above it, keeping out radioactivity at least long enough until runoff filters down to that level (let your kids worry about that). The main thing would be to keep the well clean; try to hide it, and give the water to people who need it rather than let it be self serve. Last thing you need is somebody falling in and contaminating your only water with a corpse or zombie infection.
If digging a 40ft well isn't feasible and you're in an area free of radioactive fallout and contamination then your outlook is much better. Your main contention will be with tiny bacteria that will give you "Montezuma's Revenge". A deadly curse spread to all water bodies on earth by pre-apocalypse people urinating and defecating within 200ft of water.
But there is an amazingly easy way to purify this water with simple,easy to find resources called a Slow Sand Filter. All you need is:
A watertight cylinder, ideally a large bucket or barrel. A length of pipe you can route from the bottom of the barrel to 2/3s up the it's side. Pea Gravel Sand First attach the hose to the side of the barrel as close to the bottom as possible. Route it up the side so the end of the hose some 1/2 to 2/3s up the side of the barrel and curve it over so the mouth is facing down. Rinse the gravel with clean water and sort the gravel into a pile of largest gravel and one of smallest gravel. Rinse the sand as well Put the large gravel in the bucket first, then the smaller gravel, then the sand. Make sure the sand only comes up to 3in below the bottom of the bend in the hose. When filled the water line should stay 3in above the sand. Carefully fill the filter with water, making sure not to disturb the sand and muck on top. As the filter fills water will trickle out the hose mouth without needing a pump. You have to initially cycle the water in the filter for a few days before the water is safe to drink. The organic growing muck on the top of the sand is actually killing the bacteria and needs to be kept moist and alive.
This filter gets rid of all bacteria and particulates that pollute your water but doesn't have much effect on chemically or radiologically polluted water.
