摘要：The present study was conducted to provide more information on wastewater management in developing country cities, particularly in Korhogo a city in the north of Ivory Coast. Results showed that 23% of the residences discharge their wastewater either in rivers around the city, in pipes intended for storm water drainage, or on the way for laundry, crockery and/or bath water. 43% and 34% release their water through watertight and non-watertight facilities such as septic tanks and latrines, respectively. A factory evacuates its wastewater directly into the environment without any prior treatment. Only the Regional Hospital (CHR) has a lagoon system which is in a very advanced state of dysfunctioning. The city has a sludge treatment site that receives on average between 30 and 34 m3 per day, well below 100 m3 per day (sizing volume), leading to a significant algal development in the biological treatment basins and a fairly average yield of the plant below 55% at the end of treatment.
