Your challenges
In a context of increasing urban pressure, growing environmental expectations, and heightened social sensitivity, odor management has become a major challenge for sanitation operators.

Limit the impacts of the wastewater treatment plant on residents
The perception of odor nuisances can undermine the social acceptability of facilities. Documenting and explaining episodes helps maintain trust, improve satisfaction, and defuse conflicts
Ensure traceability in the event of a complaint
When a complaint is filed, having objective, time-stamped, and reliable data makes it possible to qualify the event, provide a clear response, and strengthen transparency with stakeholders.
Anticipate odor nuisances
Sanitation activities and certain industrial processes generate odorous gases that may disturb nearby residents. Local authorities need tools capable of predicting their dispersion and limiting their impact.
How does it work ?
Olfactometric campaigns
Olfaweb® is based on five mobile olfactometry campaigns carried out in different weather conditions. Local residents can be involved to measure odors in real-life situations and identify the potential sources.
On-site meteorological station
A dedicated weather station is installed directly on the site. It provides the algorithm with precise local data, much more reliable than national forecasts, ensuring accurate modeling of odor dispersion.
Site-specific settings
The system takes into account local factors that may influence odor dispersion, such as forests, terrain, or nearby buildings, in order to refine results.
Continuous monitoring and updates
The web platform updates every 15 minutes, offering an intuitive and easy-to-use interface accessible from anywhere. It ensures continuous tracking of odor dispersion in real time.
Traceability and anticipation
Olfaweb® provides traceability in case of complaints, identifies whether the WWTP is involved in nuisances, and helps anticipate the impact of works or exceptional activities on local residents.
Our positive impact
OlfaWeb® stands out with key advantages that make it a valuable tool for municipalities and operators.

Decision Support
Beyond traceability, OlfaWeb® provides municipalities and operators with a concise overview of the olfactory impact of their facilities. This reliable information guides technical choices and helps set intervention priorities.
Intuitive Interface
Accessible through a user-friendly web platform, the tool offers clear and immediate visualization of odor events. Operators thus have direct access to information, without the need for complex training.
Community Engagement
By providing tangible, easy-to-understand evidence, OlfaWeb® facilitates dialogue with local residents and helps build lasting trust around the facilities.
