List 3 main parts of irrigation and drainage

The three main parts of irrigation and drainage systems are:

1. Water Source: This is where the water for irrigation originates. It can be a natural source like a river, lake, or groundwater aquifer, or a man-made reservoir or canal.
2. Distribution System: This part conveys the water from the source to the fields. It includes canals, pipes, pumps, and control structures like gates and valves.
3. Application/Collection System: This is how water is applied to the crops (irrigation) and how excess water is removed from the fields (drainage). For irrigation, this can involve sprinklers, drip emitters, or furrows. For drainage, it includes ditches, tile drains, and surface drains.
