• [X] I have searched all issues to make sure there isn't a request for this icon.
• [X] I have searched the current library to make sure the icon doesn't already exist.
• [X] I understand that brand icons are no longer being added and I can use SimpleIcons for my brand icon needs.
• [X] I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

To flag for water content or not in a water tank.

Give us an example of what this icon might look like.

This could be a good example: Source: https://iconscout.com/icon/water-tank-17

For water tank alert an exclamation mark "!" could be added to the left of it as I've seen in other icons, e.g. icon "water-alert".

A simplistic icon like this would do for me. Maybe, like we have with battery, a 75% 50% , 25% and empty version as well.

I have lots of rainwater water storage tanks and would be nice to have nice icon for them on HA.
