Every crop needs water to grow based on its water requirements. If there is not enough water, the crop will stop growing and will start to wither. If water is not provided over longer periods of time, the crop can dry out, forcing a premature harvest. Water replenishes during the rain. Later, farms can be upgraded with an irrigation system that can provide water at any time. When nothing is growing on the farm, water will slowly evaporate. Crops can start growing only when soil has some water.
Svaki usev ima svoje posebne potrebe za količinom vode. Ako nema dovoljno vode, usev će zaustaviti rast i počeće da se suši. Ako voda nije dopremljena tokom dužeg perioda, usev se može skroz sasušiti i pokrenuti preranu žetvu. Voda se obnavlja tokom kišnih dana. Kasnije, farme mogu biti unapređene sa sistemom za navodnjavanje koji pruža dovoljno vode bilo kad. Ako se ništa ne uzgaja na farmi, voda postepeno isparava. Usevi mogu početi svoj rast samo ako postoji vlaga u zemljištu.
