The Rheticus® cloud-based geoinformation service for monitoring displacements of the sewerage network in Milan, Italy.

The public sewerage network of Milan runs for approximately 1500 km. MM SpA, the managing company of Integrated Water and Wastewater Services of the City of Milan, has used the Rheticus® platform to identify possible surface movements caused by structural defects of its collector. Rheticus® services are available worldwide through a growing network of Authorized Distributors.

Land and infrastructure monitoring is a key activity to ensure people’s safety, environmental protection and the safeguarding of assets at all stages of the life cycle of infrastructure design, production and management.

Traditional campaigns for the regular monitoring of large and remote areas, however, employ considerable financial resources and time and are often complex to implement. The use of satellite technology allows overcoming these limitations and obtaining frequent, accurate and accessible information thanks to the wide availability of spatial information, even in open data mode.

The public sewerage network of Milan runs for approximately 1500 km. MM SpA (former Metropolitana Milanese SpA), the managing company of Integrated Water and Wastewater Services of the City of Milan, had been searching for a method to quickly detect ground surface movements caused by the structural defect of its collector that could affect the area above the primary network and adjacent areas.

Satellite radar interferometry was considered the most accurate and affordable survey method to prevent and identify possible failures of the sewage system, even in relation to the high traffic volume of metropolitan cities like Milan.

Thanks to the Rheticus® platform and its geoinformation service Rheticus® Displacement, which processes the interferometric data of Sentinel satellites, 50 points with sensitive sub-vertical movements on 24 roads with heavy traffic were identified and will be investigated in a detailed field survey.

The Rheticus® cloud-based platform provides continuous monitoring services of the Earth’s surface, ranging from the stability of infrastructures (dams, roads, pipelines, etc.), slope stability and subsidence, quality of coastal waters, forest fires, and anthropic changes to the territory.

The Rheticus® Displacement geoinformation service offers monthly monitoring of millimetric displacements of the ground surface, landslide areas, the stability of infrastructures, and subsidence due to groundwater withdrawal/entry or from the excavation of mines and tunnels.

Rheticus® Displacement provides a yearly historical analysis with monthly updates.

This service was adopted by numerous customers in various application areas after only its first months of operation.

Two success stories:

  • ANAS S.p.A.: (National Autonomous Roads Corporation): analysis of slope stability to support the planning, design and monitoring of roads.
  • MM S.p.A. (former Metropolitana Milanese): analysis of the instability of roads overlying pipelines for the detection of leaks in the water and sewage supply network.
