How effective is a water pump?
2.4.1 A: A water pump (not next to water) will service approximately 24 to 36 tiles, depending on the weather. An additional 12 tiles (approx.) will be serviced for every water tile that the pump is adjacent to. For example: W W W L P L L L L where W = water, L = land, P = pump The above pump is next to 3 water tiles, therefore, it will provide 60 to 72 tiles with water. I think that each tile requires 600 gallons of water.
