Cutting-edge technology for pipeline and connection diagnostics
For all maintenance operations on your pipelines and connections, as well as before the handover of construction work, Séché Assainissement has all the equipment and expertise required to inspect, examine and map your networks.
We detect leaks, seepage, corrosion and other defects to provide you with a report and pictures that identifies, categorizes and locates any anomalies, which is essential to be able to plan targeted and effective repair and maintenance work.
Video inspection
- Cameras mounted on carts, rafts or drones to assess your pipes
- Portable cameras with a range of up to 30 meters suitable for small-diameter pipes
- Satellite cameras to inspect connections from the main pipeline
- Visual inspection vehicles
As an authorized “network detection” contractor, Séché Assainissement uses 3D plotting technology and is certified to define the positioning of sanitation networks and facilities. This process is essential as the reform made to the Planned Work Declaration and Declaration of intention to start work requires simplified street plans for all underground systems before January 1, 2026.
Backfill must be suitably compact to ensure new or renovated sanitation networks continue to operate effectively over the long term. Séché Assainissement uses a constant-energy penetrodensitograph mounted on caterpillars and able to operate on all types of terrain to conduct compression tests and ensure the backfill complies with the required standards.
Depending on the characteristics of the structure (gravitational or pressurized, circular or rectangular) and the level of the water table, we carry out impermeability tests using air or water to verify the impermeability of your networks. The findings are compared with industry benchmarks (COFRAC).
