With the development of sewerage, conduit stock has increased. In the meantime, the number of accidents caused by facility aging is also on the rise. In sewerage, stock management and remedies for aging facilities are major issues. Therefore, the alteration and repair of facilities must be carried out based on deliberate plans that target those specific issues. Aiming to realize a safer and more secure life and to ensure its sustainability, JIWET has been working on proper stock management in sewerage via joint research.
