Gameplay balancing potential: Large Tank (50 000 litres) Vs Vertical Tank (31000 litres) From size estimation, something is not logical. Either the vertical tank holds too much volume, or the large tank should hold way more than 50 000 litre. However note that at 6 litre/s per well, it would take 1 year to fill the large reservoir. Unless there is something else coming in for water well and water hauling, the large tank is somewhat overkill at the moment. Thanks for reading!
