(This article belongs to the Special Issue Municipal Wastewater Treatment and Reuse for Irrigation)
The practice of irrigation with municipal wastewater has evolved from avoidance of surface water pollution to beneficial reuse of water and nutrients for crop production. The ability of the soil to filter out pollutants and pathogens has been documented, such that groundwater quality is not degraded where recycled water to irrigate crops used for human consumption. The example of successful practice of the Castroville project in Monterey County, California illustrates safe reuse of recycled water for crop growth, marketing of crops grown into the fresh produce market, and groundwater protection. Impediments to the future more widespread reuse of recycled water for agricultural irrigation are also discussed. Many of the same technological advancements that have supported the development of modern agricultural water reuse projects have also improved the feasibility of various competing urban water reuse applications. The effects from increasing water scarcity has also had an impact on the quality and quantity of water available for agricultural water reuse projects. The historical practice of developing centralized and regional wastewater treatment facilities near a suitable surface water discharge location may need to be modified for better consideration of agricultural irrigation in integrated water resources planning.
