Combined sewer overflows (CSOs) have been recognized as one of the major causes of surface water quality impairment, particularly drinking water supplies. Occurrence of CSOs as a discharge of an untreated mixture of wastewater effluents and stormwater into waterbodies upstream of drinking water sources may potentially deliver high amounts of fecal loads to downstream intakes, causing periods of elevated concentrations. The CSO-induced peak periods at the intakes must be characterized with regards to the level of microorganisms during these periods while treatment processes in drinking water treatment plants must effectively reduce concentrations by the required amounts.


Les débordements d'égouts unitaires (DEU) sont reconnus comme l'une des principales causes de dégradation de la qualité de l'eau de surface, en particulier des sources d'approvisionnement en eau potable. Lorsque les DEU, des rejets combinés d'eaux usées non traitées et d'eaux pluviales, se produisent dans les sources d'eau potable, ceux-ci peuvent momentanément augmenter les charges de contamination microbienne à l'eau brute des usines de production d'eau potable. Les concentrations de micro-organismes doivent être évaluées afin d'assurer une réduction adéquate des concentrations acceptables à l'eau potable.
