Waterlogging and salinity control
Drainage of irrigated land is required to reduce waterlogging and soil salinization that inevitably accompanies waterlogging in arid zones. At present, about 20-30 million hectares
of irrigated land are seriously affected by salinity.

Water quality management and environmental effects
Agricultural drainage water must be properly managed to prevent deterioration of water resources by salts, toxic elements, sediments, fertilizers and pesticides. Water conservation, re-use, safe disposal and eventually water treatment are the major components of drainage water quality management.
Additional water resources can be available for irrigation through treatment and re-use of wastewater. The fertilizer value of wastewater is also an agricultural benefit. Since nutrients are removed from the water cycle there are additional environmental benefits.
