Non-conventional source of irrigation - Drainage water

Explanation:
Drainage water is the excess water that is drained out from irrigated fields or from other sources like rainfall, seepage, etc. This water is collected in drainage pipes or channels and is usually discarded as waste. However, in recent times, drainage water is being used for irrigation purposes.

Non-conventional source of irrigation:
Non-conventional sources of irrigation are those sources that are not traditionally used for irrigation purposes. Drainage water is one such source. Other non-conventional sources of irrigation include treated wastewater, saline water, etc.

Advantages of using drainage water for irrigation:
1. Conservation of freshwater resources: The use of drainage water for irrigation reduces the demand for freshwater resources, which are already scarce in many regions.

2. Nutrient-rich water: Drainage water contains nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth. By using drainage water for irrigation, these nutrients can be recycled, reducing the need for chemical fertilizers.

3. Cost-effective: Using drainage water for irrigation is a cost-effective solution as it eliminates the need for constructing new irrigation systems.

4. Improved soil quality: The use of drainage water for irrigation can improve soil quality by reducing soil salinity and increasing organic matter content.

Conclusion:
In conclusion, drainage water is a non-conventional source of irrigation that has several advantages. However, it is important to note that drainage water may contain pollutants, and its use should be regulated to ensure that it does not harm human health or the environment.

Yes, the drinage water is non-conventionl source it is treated defire the use and the drinage system it will all the wastes in the drinage and we can use them in irrigation.
