Learning outcomes
Students will acquire good theoretical knowledge on trenchless technologies used for the laying and rehabilitation of belowground network, with focus on aqueducts and sewerage.
The course will also deal with the aims of the 2030 Agenda for Sustainable Development Goals. Some topics and management approaches are consistent with:
Goal 6: Ensure access to water and sanitation for all.
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy.
Goal 8: Promote inclusive and sustainable economic growth, employment and decent work for all.
Goal 9: Build resilient infrastructure, promote sustainable industrialization and foster innovation.
Goal 11: Make cities inclusive, safe, resilient and sustainable.
Goal 12: Ensure sustainable consumption and production patterns.
Goal 15: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss.
Course contents
Condition of national hydraulic infrastructures, with particular focus on the aqueduct and sewer networks in operation.
ARERA’s Regulatory framework .
The course will describe the use of trenchless technologies from the inspection techniques, planning and design, to the final test.
Trenchless technologies framework
Existing hydraulic infrastructures issue and damage classification. Leak detection techniques; assets management; investments in water networks.
Classification of trenchless technologies; fields of application; environmental and social benefits; current regulatory framework.
Methods for measuring and evaluating the environmental advantages and benefits of trenchless technologies
LCA analysis (life cycle assessment), integrated by final calculation and critical evaluation of circularity indicators, in terms of improving durability and reusability, reducing carbon and environmental footprints, guaranteeing the performance of existing hydraulic infrastructures.
INSPECTION TECHNOLOGIES
Preliminary investigation in urban and extra-urban areas and selection of the best appropriate technology to be applied.
Closed Circuit Television (CCTV) video cameras and GPR (ground penetrating radar); mapping of belowground hydraulic infrastructures; trenchless application in BIM (Building Information Modeling).
