The Almendares River in Havana, Cuba, receives wastewater from over 200,000 inhabitants, resulting in very poor microbiological water quality downstream due to high faecal bacterial indicators (FBIs). This water is used for urban agriculture and recreation, despite not meeting microbiological standards. This study compared FBI removal in three wastewater treatment plants (WWTPs): a conventional facility, a constructed wetland (CW), and a solar aquatic system (SAS). Natural systems (CW and SAS) showed approximately two log units higher FBI removal efficiency than the conventional plant. The large conventional WWTP was found to have a negative impact on the river's microbiological quality.
