Water Well
Water wells are excavations providing access to groundwater. Water is drawn up with buckets or water bags by hand. In the country, the well's resultant water is typically pure and sweet-tasting, as within the game era there is little to poison the groundwater. Wells are built adjacent to rivers because the surrounding soil produces a better tasting water. Wells can be built near oceans, even within a hundred yards in some cases, as the soil leaches out salt and enables access to fresh water.
All habitations possess at least one well, even a lone farmstead. In larger habitations, a minimum of one well is needed for every 250 persons. These are carefully spaced out so as to not denude the water table in any one place.
Construction
Wells are sunk by hand digging, with a structure lined with brick or stone as the excavation proceeds. Once the water table is reached, the lower construction floods naturally. Well diggers can expect to encounter water within 18 to 26 ft. at the most, but wells down to 43 ft. are known.
However, it can be impractical to dig wells where hard rock is present, or where the water table is simply too far down. For this reason, settlements are founded on hills only when the water table is high enough. We may assume that the location of settlements and smaller habitations are not accidental, but are demonstrative of those places where access to well water was available.
