No. Here only tank water, this means bacteries from bird shit.
Still not sure if you're joking, or paranoid, but I'll play along.
I've made over 300 kit brews with tank water (tank is on shearing shed, surrounded by cypress trees), complete with bird shit, possum shit, dirt, cypress needles, and the odd dead rat.
Also, I usually rinse bottles after drinking, and store them upside down, (sometimes for months) then just fill. (unless they have spiders in them).
I've only ever had 2 brews that I felt I had to tip out, and I'm pretty sure they were brews that I had forgotten about, and had sat there with a dry airlock for about 6 weeks.
Now that I'm AGing, I do take a little more care, only because of the extra time involved, I don't want to waste any beer, and because of the waiting time while mashing, I can spend some time getting those stains out of the bottles.
All in all, if you've got plenty of time, and are at all worried, just keep cleaning.
Good luck.
