The Graie, an internationally-regarded hub for waterwise territories, is an association that mobilises and connects stakeholders in water management, aquatic environments and urban development.

Created in 1985, the Graie has over 300 members: public and private professionals, local authorities, companies and research laboratories.

The Graie's action aims to develop a shared culture, based on knowledge and the exchange of experience, in order to improve water management practices.
In this way, the Graie contributes to the uptake of knowledge and to the evolution of practices and regulations on water. The organisation of the Novatech and I.S. Rivers conferences is one of a key way in which Graie pursues its mission.

The OTHU (Observatoire de Terrain en Hydrologie Urbaine) is a research laboratory "outside the walls" for the observation of urban discharges and their impacts on the receiving environments. It has a particular focus on stormwater, and onthe Lyon region, and aims to propose new solutions for the design and management of stormwater and urban sanitation.

It is a research federation (FED 4161) bringing together 9 research establishments, 12 laboratories [100 researchers], the Graie and numerous operational partners.

Lyon Metropolis is a model in terms of sustainable stormwater management. For more than 30 years, it has been developing numerous experiments for a more permeable city and nurturing close partnerships with the research community. In order to improve the functioning of sewage systems, limit runoff and fight against heat islands, the management of rainwater on a parcel basis has become the basic rule in urban planning documents. 

Lyon Metropolis brings together 59 municipalities and is very involved in the daily life of its 1,300,000 inhabitants. On January 1, 2023, drinking water management will be transferred to public control with the creation of Eau publique du Grand Lyon (Greater Lyon Public Water).
