How about making a reservoir (clay and board and plaster) and stretch the canal (clay, board and plaster) in the village? The water extractor is limited to buckets. If you try not to cross over the waterway, make a bridge with a wooden plate.
The intention of making the engine well is increased by one, and the labor for carrying water from the well to the cistern is enormous, and automated equipment is indispensable for enlarging the village.
Because automation elements such as engines were born, I think good to advance the automation of agriculture.
溜池（粘土と板と漆喰）を作り水路（粘土と板と漆喰）を村中に張り巡らせてはどうでしょうか？ 水を取り出せる器はバケツに限定するなど。水路の上を渡れないようにしたなら、板で橋を作るなど。
エンジン井戸を作る意図が１つ増えますし、井戸から水槽に水を運ぶ労力は多大で、村を大きくするには自動化された設備が欠かせません。
エンジンのような自動化の要素が生まれたのですから、農業も自動化を進めても良いのではないでしょうか？
