Assessment of Bacterial Load in Urban Wastewater in Drainage Canals in the Cities of Abidjan, Bouake and Yamousoukro, Côte d'Ivoire

The microbiological quality of urban wastewater presents important environmental, health and political challenges. lack a water treatment system leads to knowledge about the variability in major cities Côte d'Ivoire.
 Aims: purpose this study is assess level pollution drainage channels different agglomerations.
 Methodology: Indicators environmental (mesophilic aerobic germs) faecal contamination (fecal coliforms intestinal enterococci) were analyzed at 14 upstream downstream sites Abidjan, Bouaké, Yamoussoukro during rainy periods dry season.
 Results: Our results show an translated by abundance bacterial indicators which mesophilic germs can reach average loads going from 3x107 cfu/100 mL 7x109 witnesses fecal contaminations 3x105 7x107 for 6x105 cfu/100mL 1x107 enterococci These fluctuate according configuration sewerage systems hydrological conditions. In season, significant dilution certain indicators, precisely enterococcus, be observed. number microorganisms encountered exceeds values indicated WHO guidelines (WHO, 2017) standards force discharge.
 Conclusion: Creation strong manage them before any discharge waterbodies have priority. This could reduce risks point view. cause mild or serious infections.
