Excerpt

A drinkable water supply in Latin America is a major problem due chiefly to a concentration of population in a small land area. Sixty percent of the people live in cities of over 279 million and this population is concentrated in 20% of an area with only 5% of the region's water resources.

In Latin America, 71% of the population has a drinkable water supply but only 38% have sewer service. Nineteen percent of the wastewater receives some type of treatment while only 8% receives a secondary treatment. According to the World Health Organization (WHO) (1997), 567 m³ s^−l of untreated urban wastewater is disposed of in surface waters. If, by the year 2010, this type of disposal service were expanded to 90% of the population, more than 100 million m3 of sewage would be produced, seriously aggravating the water contamination problem (CEIPS 1997).
