Using water bladder for clean and gray water tanks

[pengyou]

Is it possible to build an area that is about 90 gallons big and then put 2 ,80 gallon bladders in it? On bladder would first be filled with potable water. As it is used and becomes gray water, it would be pumped into the second bladder. The decrease in the volume of the first bladder should be proportionate to the increase of the second.

Anything is possible ... well maybe electing a Democrat in Oklahoma breaks that rule .... but at a price.

I would worry that it is a disaster waiting to happen should either of the bladders fail. One issue would be that the fresh water bladder would expand to fill the space available on the floor of the enclosure, and it might require significant pumping pressure to force the grey water into its own bladder, and nothing to stop it squeezing right back out again when the pump shuts off.
