I've gone to the point of having a contingency plan in case I even lose my pants! 
I where a paracord bracelet made with about 18' of paracord. I have Ranger Banded to this a Victorinox Classic SAK and a Boy Scout Hot Spark ferro rod. I figure with the Ranger band, spark, knife and cord, I at least have something to work with.
As far as a water container, that would involve having something on a belt or in a pocket, which is not part of my last ditch contingency plan, but perhaps you could tote a quart Ziplock freezer bag or a Platypus 1L canteen "bag." I have one and have kept it in belt kits before. The freezer bags have worked for me as well.
Just some ideas!
