This depends not only on the absolute quantity of water available, but on the scale of irrigated agriculture imposed on a region. In areas where irrigated agriculture frequen

Irrigation with Treated Sewage Effluentswerage systems in the nineteenth century, sewage (domestic wastewater) was used at “sewage farms”, and by 1900 there were numerous sewage farms in Europe and in the United States (Reed and Crites 1984; Sterritt and Lester 1988). Although these sewage farms were used primarily for waste disposal, inc

Drainage Water Treatment and Disposalirrigated lands. It is a common agricultural practice to reuse surface return water or to discharge runoff to local water courses, usually for downstream reuse. However, this practice has limitations for the disposal of subsurface drainage, which contains not only accretions of dissolved salts but a
