Agriculture accounts for about 75 percent of all world water uses. Agriculture water reuse is an important sustainability, conservation and cost-reduction opportunity. Many national and international organizations have recently recognized benefits of wastewater use in agriculture:
– the associated decrease in pressure on freshwater sources.
– wastewater reuse increases agricultural production in regions experiencing water shortages, thus contributing to food safety.
-the avoided cost of exctracting groundwater resources: energy required to pump groundwater can represent up to 65% of irrigation activities.
-the nutrients naturally present in wastewater allow savings on fertilizer expenses to be realized, thus ensuring a closed and environmentally favorable nutrient cycle that avoids the indirect return of macro-and microelements to water bodies.
