Water storage.
You want to allow 2-4 litres of water per person per day for drinking. The variation is in terms of age, activity levels (are you cycling around and sweating or sitting at home?) and medical needs. If in doubt err on the higher end. Also remember to allow for pets. You want another litre of water per day per person for washing and cooking. I'll discuss hygiene in a low water scenario in a subsequent post.
If at all possible you want to be storing water in a dark container, not a white or clear one, to prevent algae growing. We use 20L ex army Jerry Cans for this like https://www.militarykit.com/products/nato-plastic-water-container-20l-black for camps. You used to be able to pick them up for about twenty quid but a quick look today shows the price seems to have jumped to about £40, presumably as a result of everyone panic buying because of the government announcement which is another reason they shouldn't really have gone "lol, fend for yourselves".
