Better understand to better manage

This outdoor laboratory plans to acquire reliable data on urban wet weather effluents on their impact on receiving water, in order to provide results, knowledge, and methodologies to assess the sustainability of urban water system and to propose some support for operational decision making.

	A research teams Federation 8 Universities and Engineering Schools 13 Research Laboratories, 80 Researchers Operational partners: Urban Community of Lyon, Water Agency, Ministries of Equipment, Ecology and Research; Rhone-Alps Region
	A long term and multidisciplinary approach Climatology, Hydrology, Hydraulics, Soil science, Chemistry, Biology, Hydrobiology, Social science, Economy
	Research actions linked to end-users needs - Hydraulic and pollutants loads in urban catchments during dry and wet weather - Impact of discharges on soils, waterbodies & aquifers - Interaction between urban and rural areas - Development of strategies for sustainable urban water management
	An original instrument of observation based on long term monitoring systems,with on-line monitoring sensors and samplers, dedicated to the global assessment of rainfall impact 5 experimental catchments in Lyon agglomeration, representative of : - Urban and peri-urban areas, - Combined and separate sewers systems, - CSOs, retention and infiltration tanks, - Impacts on small periurban watercourses and aquifers.
	A strong effort devoted to results dissemination - Web site - Technical sessions for operators (technicians & decision-makers) - Scientifc international workshops - Periodic meetings between OTHU researchers - Scientific and technical publications
