CERN’s sewage water is treated in public wastewater treatment plants. Water from various sources is released through the site drainage into nearby watercourses: cooling water, infiltration water pumped from tunnels and precipitation runoff. The HSE Unit operates water monitoring stations at 13 water release points on the sites’ drainage system.

Prior to release, ensure that the HSE Unit has granted the permission to release a definite volume of water. Please fill in a request prior to discharge at the following address: SNOW.
