Combined sewage colifonn bacteria are important as II1dicators of pathogenic microorganisms and of their possible discharge into tbe environment Whilst specifYll1g limits for viruses, most legislation recognises the difficulty of enumerating such organisms and also prescribes limits for coli forms. Despite the importance of these organisms, little IS known about their numbers and behaviour 111 sewerage systems. A data coUection progranune IS descnbed which has momtored dry and wet weather sewage coliform bactena and also sediment bactena These data are used to revIew recent UK recommendations for assessing bacteria numbers 111 stonn dIscharges. It IS concluded that relationshIps between hactena numbers and otber physicaIlchemicai parameters may be developed during DWF, but are seasonally and catchment dependent. Extension of DWF measurements to predict stonn bacteria may be possible with more data.
