Service Oct 28, 2026 | The Federal Office for the Environment (FOEN) operates a hydrological measuring network with 260 measuring stations on rivers and lakes throughout Switzerland. Groundwater levels and spring discharges are measured at 70 additional measuring points. At these measuring stations, continuous series of measurements are created automatically.
In addition, the water quality is monitored according to defined sampling plans. The quantitative data is automatically collected at the measuring stations and fed into WISKI via the query center (AZ). The purpose of this procurement is to evaluate a provider who is able to reimplement, configure and further develop the new HydroSys system for collecting, validating and maintaining Switzerland's hydrological data in accordance with the technical, organizational and professional specifications on the basis of standard software, and to ensure operation, maintenance and support.
