Why is waste water used for agricultural purposes?

Wastewater is used for agricultural purposes primarily because it provides a reliable source of water and essential nutrients for crops. Utilizing treated wastewater can help conserve freshwater resources, especially in water-scarce regions. Additionally, it can reduce the environmental impact of wastewater disposal, turning a potential pollutant into a valuable resource for food production. However, proper treatment and management are crucial to ensure safety and prevent contamination.
