SIPIBEL – Bellecombe site


Bellecombe site –Sipibel– was created in 2011 in order to study the characterisation, treatability and impacts of hospital effluents in a urban sewage treatment plant.


It is composed of: :
‐ the CHAL hospital, opened in February 2012,
‐ the Bellecombe sewage treatment plant, with 2 distinct treatment lines allowing to isolate hospital effluents, and
‐ receiving waters, the Arve river.

Two projects are based on the Bellecombe site - SIPIBEL :
‐ the franco-Swiss Interreg project IRMISE Arve aval (2013 -> Juine 2015) focusing on the impact of Micropollutant (and pharmaceutical) Discharges from wastewater treatment plants downstream of the Arve catchment and on the Genevese Aquifer
‐ the RILACT project (Risks and Measures related to pharmaceutical, detergent and biocide discharges in hospital and urban effluents) which started in November 2014 in response to the "Innovation and change in practices: micropollutants in urban water" national call for projects.



A research and observation site

- A field observatory :
which aims to monitor effluents and their impacts on receiving waters, for a minimum period of 3 years following the opening of the hospital, with data banking.

- Research actions,

developed in association with the field observatory – Theses actions are part of the SIPIBEL research programme, divided into 4 themes: 1-pollutants flows, 2-treatment, 3-risks, 4-sociology -

-Coordination and enhancement of the project

with: a website, scientific publications, conferences and press conferences.



The Bellecombe “Syndicat" (managing the sewage treatment plant) and the Alpes Léman Hospital (CHAL) have associated with the Graie, The Rhone-Alps Group of Research on the Infrastructures and Water, to put together a group of specialised scientists, stakeholders of the territory and institutionnal partners.
