how Jumbo jets maintain their Center of gravity with freshwater and sewage needs on board

Question

So i worked on a ship and i know we had various tanks that could be filled and emptied to modify our CoG

in an airplane that could be extremely dangerous and could have several thousand kilo’s of sewage after a long flight how do they maintain such a critical factor for flight?

EDIT:
I understand that flying is different from floating i was merely using it as an example of a system i knew and how it worked

>in an airplane that could be extremely dangerous and could have several thousand kilo’s of sewage after a long flight

Assuming everyone aboard takes a dump and pee on a 16 hour flight, that’s still maybe half a tonne of sewage at most, spread out between several washroom points.

In comparison, the Boeing 747 variants can hold at least 180 tonnes of fuel, mostly concentrated at the wing area.

That half ton would be nothing, you’ll probably get more CoG shift from half a dozen people getting up from their seats and walking around the cabin. If there is a problem, the pilot or autopilot can just adjust by trimming the flight controls.
