Water reuse agricultural irrigation

In recent years, efforts have been undertaken to conserve water due to the growing demand for a limited resource. As a result, water reuse is being employed, especially in the Western United States. Water reuse is when wastewater generated from a community is reclaimed for a beneficial use such as irrigation for ornamental or agricultural crops, decorative water features, industrial application and with advanced treatment potable water. The use of reclaimed water may expose the public to chemical and microbial contamination from the wastewater stream. Therefore, for each type of beneficial reuse, treatment standards are being established to protect public health. 

Irrigation return flows. When farmers irrigate agricultural land, water not absorbed into the ground can flow into reservoirs for reuse. This return flow often picks up pesticide or fertilizer constituents, potentially rendering it hazardous. Because this water may be reused on the fields, it is excluded from the definition of solid waste.
