Large Scale ATO Question

So here's my question, we can all agree that setting up an ATO for an aquarium is pretty easy and straightforward. However here is my situation.

Inside building 1 I have 1 75 gallon and 1 100 gallon (both tanks include sump water volume).
Inside building 2 I have 1 65 gallon, 1 75 gallon, and 1 20 gallon. Also inside building 2, I have a 75 gallon salt and fresh water reservoir. The fresh water reservoir is fed by a 4 stage RO/DI system. Both reservoirs are attached via plumbing to each other with internal pumps and ball valves to prevent the salt water back flowing into the fresh water.

The two buildings are separated by a distance of about 50'.

As you can imagine, topping off all aquariums is no doubt a task.

What I'd like to do is design an ATO which can be fed by the fresh water reservoir and top off each system independently from each other as needed.

Looking for ideas to accomplish this. Thanks.

Yeah however big of storage container you need and float switches and pumps for each system.

On my 120 I have a float switch on my rodi that continually fills my container as needed.
