Irrigation with Reclaimed Municipal Wastewater - A Guidance Manual is for use in the planning, design, and operation of agricultural and landscape irrigation systems using reclaimed municipal wastewater. It is written for civil and sanitary engineers, agricultural engineers, and agricultural extension workers and consultants. The manual is also useful as a reference for public works officials, municipal wastewater treatment plant operators, and students at colleges and universities. The text emphasizes irrigation for the purpose of optimizing crop production; therefore, it includes detailed instruction in the calculation of crop water requirements. Furthermore, the benefits and limitations of using reclaimed municipal wastewater for agricultural and landscape irrigation are discussed, as are other topics of special interest, including water management for salinity and sodicity control, and economic and legal aspects of reclaimed wastewater irrigation.
