That thing has a MEGA footprint. You seriously need to rethink the geometry of that thing. It would be better as a wall hugging shape like a rectangle.
You should put an extra tank with the brine water for washing, so there is zero waste. Anyways that tank would need to be 3 times bigger than the other one. Also I suppose that is a chlorine resistant CTA (Cellulose Triacetate) membrane instead of a TFC (Thin Film Composite), cause I see zero prefilters, not even sediment ones.
