UN: Rising reuse of wastewater in forecast but world lacks data on 'massive potential resource'
Date:9/4/2013

nent data are available, in part because many Latin American countries do not have well developed wastewater collection and treatment systems. In 8 of 15 Latin American countries, less than half the population is connected to wastewater collection and treatment systems

Rapid urbanization without sanitation facilities has caused major downstream pollution problems in this region. The urban population is projected to further increase by 130% in 2025 and by 166% in 2050

In Chile, untreated wastewater was used directly for agricultural purposes until 1992. With widespread occurrence of cholera in Latin America, the direct use of untreated wastewater was restricted in the country.

Water scarcity is not the main driver of wastewater use in most of Latin America. Rather, farmers engage in wastewater use because it provides a low-cost source of plant nutrients. Wastewater use in the region is particularly important, given that the shortages in supply of phosphate and potash fertilizers are projected to increase to 3.5 and 4.1 million tons by 2014.

Europe

Complete information on wastewater generation, treatment, and use is available for only 10 countries in Europe Cyprus, France, Germany, Italy, Malta, Netherland, Poland, Portugal, Spain, and United Kingdom.

Most of this information pertains to the last 10 years. Partial data are available for almost two-thirds of Europe, including Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Greece, Hungary, Ireland, Luxembourg, Kosovo, Monaco, Montenegro, Republic of Macedonia, Romania, Serbia, Slovakia, Slovenia, Sweden, and Switzerland. No data are available for Albania, Finland, Iceland, and Norway.

Most of the wastewater generated in Europe (71%) undergoes treatment.

In southern Europe reclaimed wastewater is used predominantly for agricultural irrigation (44% of the wastewater projects) and urban or environmental
