A moat or pulley system of irrigation is one that involves pulling water up from a well or other water source in order to water plants and other crops. It is not often in use as it can be time consuming and may not always be as efficient as other methods of irrigation. On the other hand, it does not cost a lot of money to install a moat or pulley irrigation system as it does not require vast technology or machinery invested in it.
This method will also help a landowner conserve water and only use what they need to use. In this respect, resources will be saved and there will also be financial savings too as the water is not being wasted where it is not needed. In areas that suffer from long, dry summers this method of irrigation may be a worthwhile investment as it will help the landowner conserve the water until a time when they need to give the land a little helping hand.
This system may be used when the land is affected by drought or sustained strong sunshine. The land has become too dried up and in order to give the plants and crops a better chance of survival, an irrigation system may need to be used.
