Thinking of adding a water storage tank in my attic while being on a city water system for emergency use. Anyone have any suggestions on how it could be set up?

I'm going to mount over closet after installing additional cross section of deck support. Volume to be determined by biggest tank fitting into 24"x 48" drop stair opening and weight that could be supported.

I'm not a professional., But I did stay at Holiday Inn Express last night.

So no more than 2' around over a closet. You'll be alright as long as the closet don't fall over.
Make sure the container is sealed or it will be putting a lot of moisture into the attic.

I bet you can stuff a pretty big one of these through that opening:

Bladder Water Tanks are designed to provide you with a flexible tank that can safely store your drinking water. Made from NSF 61 and FDA compliant materials, these tanks have stored drinking water for FEMA operations, rural construction sites, residential water storage and more. Sizes range from 2.5 to 210,000 gallons source

Thinking of using regular water well tank. Running all house water supply through tank, with check valve to prevent back flow.

Here's another way to store some water if you know of an emergency in advance.

You do not want a tank with the water surface open to the atmosphere that draws in (non-sterile) air when you use water (and the air escapes when the tank refills).

So nowadays bladder tanks are the best choice. The tank should be positioned with the air valve upwards and the air valve should be left open. Optionally pressurize the tank while it is empty to about 3 PSI and close the air valve.

The higher you prepressurize the tank to, the less water will enter the tank before system pressure (water main pressure or well pump pressure) is reached and the inflow stops. Meanwhile if you let the tank fill up and then close the air valve, a partial vacuum will develop in the tank in time of need and gravity will not be enough to get water out.
