DESCRIPTION:Dr Luca Rossi\, ECOL-EPFL\n... "or why project partners thrown
  in Lausanne's sewer system no longer swims in Vidy Bay".\nDuring rain eve
 nts\, the total amount of the wastewater/storm-water mixture cannot be tre
 ated in the wastewater treatment plant\, and the overflowed water goes dir
 ectly into the environment (lakes\, rivers\, streams). This untreated wate
 r is recognized as an important source of pollution. For this reason\, the
  monitoring of the water flow and the water level is of crucial environmen
 tal importance. However\, the harsh and hostile environment inside sewers 
 systems\, such as constant humidity\, solid debris or hydraulic turbulence
 s\, make traditional water monitoring systems unpractical. \nThe HydroPix 
 system proposes a novel camera based approach to the automatic monitoring 
 of sewers\, targeted at wastewater system managers. The developments were 
 conducted in collaboration with an industrial partner (Etrinex SA)\, the B
 iomedical Imaging Laboratory (LIB) and the school communication systems at
  EPFL. \nThe vision system performs water level and flow velocity measurem
 ents without any contact with the water.  In situ tests in various sewers 
 configurations have shown the ability of the HydroPix to perform accurate 
 monitoring of hydraulic structures. Visual information provides a better u
 nderstanding of the flow behavior in combined sewer overflows and helps de
 cision makers in defining future investments.\nThis talk will present an o
 verview of the project in the context of Lausanne's sewer system\, and des
 cribe its main hardware and software challenges. It will also make a case 
 for the benefits to be drawn from cross-disciplinary approaches.
