The utility sink that I would dump the lambic into is 1 foot away from where I do all of my bottling. Normally I wouldn't be a stickler and worry much about wild yeast contaminating my future beers, but shortly after I made my first batch of lambic I checked the sump pump hole under the utility sink and it had a pellicle very similar to that of my lambic.
Unless you're dipping your bottles into the sump pump hole it still shouldn't be an issue for bottling so long as you're cleaning and sanitizing your bottles properly. The air all around you is filled with fungal spores, pollen, bacteria, dust, etc. I honestly think you're worrying way more about something isn't an issue. Unless you want the City to come out and talk with you I would not dump anything down the storm drain.
