Household need

Water

Work out how much water your household needs, where to store it and what to do during an interruption.

Start here

Work out the amount before buying containers.

Water is heavy and storage space matters. Begin with a household target, then choose a manageable mix of sealed bottles or suitable containers.

Water library

Start with a realistic drinking-water target, then account for cooking, hygiene, pets and household-specific needs.

Estimate drinking water or broader household water needs, total weight and practical container combinations.

Compare manageable container sizes, record stored drinking water and see the gap against a household target.

Compare sealed bottles and reusable containers, understand their weight and choose a manageable mix for your home.

Understand what common water-treatment methods can and cannot do, when official instructions take priority, and which product claims matter.
