Do you re-hydrate your yeast ? I would not, given this problem.
My suggestion is to throw out any suspect plastic items such as fermentor, airlocks, auto-syphons (if you use one to transfer to the fermentor)
Use star-san at regular strength and DO NOT rinse it off.
I turn my fermentor sideways (better bottle) about 1/4 filled and rotate it about 90 degrees every 10 minutes or so. I also splash the star-san all over in there to make sure all surfaces are sanitized.
My guess is it is brewing practices and not the water.
Try this (above) and if it does not work THEN it IS your water.
On another note:
I have well water with high iron content and cannot use it. It sucks to have to buy 10 gal of water every brew day, but for $10 or so, you know the beer will come out good. Cost for my average 5 gallon all grain batch is about $30 but that's still about $.54 per beer. Cheaper than going out where I pay $4-5 in my area at the clubs. Good luck !
