ABSTRACT

Solutions for storm sewage discharge from urban areas and waste waters management are presented in the paper. Contaminants carried by fall runoff from drained sites such as roads, car parks, squares, etc. pose a real threat to the natural water environment. The literature data gathered by many researchers has proven the maximum contaminants concentration in the storm sewage to occur in the first phase of the fall that tend to last from 15 to 20 minutes. During that phase observed contaminants concentration, which in general tend to consist of total slurry, COD, and chlorides in thaw periods, can be the order of highly concentrated industrial waste, therefore pre-treatment of storm sewage prior to its discharge into the collectors seems unquestionable. The most favourable and proper ways of storm sewage treatment shall be simple, semi-natural retention and infiltration systems, where processes leading to contaminants reduction are very much alike the ones in the natural water-soil environm

Key words: storm sewage, thaw, first runoff wave, sedimentation, infiltration.
