Colombia is facing a growing contamination of its water resources, since many rivers (near which more than 90% of the total population is settled) are polluted by raw wastewater discharges. Currently, the average coverage of wastewater treatment in the country is around 12%. There is some research work showing that anaerobic systems followed by natural systems are a good technological combination for small municipalities and rural areas. A performance evaluation of the system septic tank (ST) + Anaerobic filter (AF) + Sub-surface Constructed Wetland (SSW) was carried out in the towns of Ginebra and La Voragine, Valle del Cauca region, Colombia.
