A brief review of the characteristics of storm and combined sewer flows is followed by a general discussion of the purposes for and requirements of a sampling program. The desirable characteristics of automatic sampling equipment are set forth and problem areas are outlined. A compendium of over 60 models of commercially available and custom designed automatic samplers is given with descriptions and characterizations of each unit presented along with an evaluation of its suitability for a storm and/or combined sewer application. A review of field experience with automatic sampling equipment covers problems encountered and lessons learned. A technical assessment of the state-of-the-art in automatic sampler technology, and design guides for development of a new, improved automatic sampler for use in storm and combined sewers are presented.
