For Water, I have the store bought bottled water that I use and rotate but I also have the SOS emergency water packets ready to go on my bug out bag. I just recently found out about the Blue can water; where it has 50 year shelf life and stocked a few of those as well. It's on the expensive side (shop around online for cheapest price) but for long term, for me its worth it so i don't have to keep replacing and rotating. Get the Survivor Filter as well to go along with your water supply, it filters better than lifestraw.
