What I do is to drain the tank then refill, adding a couple of ounces of
household bleach.  I drive around a few days with that sloshing around in
the tank, then drain it and re-fill.  Drive with that a bit, then drain
and  fill again...and use that water as "good water"....I sometimes make
coffee from that tank, I even drink it (rarely) when I am really thirsty
and out of other water...  Depending on how long I've gone between fillings
of the tank, I repeat the bleach douche before I really trust that water
for human consumption..

  I usually keep my drinking and cooking water in gallon bottles, filled
from good sources and kept fresh.
