This is terrific! Thank you. Parenthetically, I recently started using a wonderful mod called Improved Aqueduct district, which gives the district a number of buildings (such as bath, sewer, water purification, etc) each yielding Amenity and/or Housing benefits, making it a lot more satisfactory to use a valuable hex for an Aqueduct. The mod gives an additional way to take the population cap pressure in mid game. Again, great article thank you OP
