This massive, gravity-fed water jug promises to filter enough bacteria, viruses, and parasites from 100,000 liters to qualify as municipal drinking water. Newly arrived souls in Pescadero are frantically stockpiling these things, treating it as proof that they are more resourceful than the locals who just know where the good spring water is. Possessing this 'virtually indestructible' behemoth instantly convinces your neighbors that your survivalism is scientifically sound and spiritually elevated. It will, of course, fail spectacularly because the sheer weight of the finished, purified water will make the thing a monumentally impractical, overly heavy decorative boulder.
