Developing multipurpose underground conduits
Multipurpose underground conduits are situated under roads and house electrical and telephone cables, gas piping, and water supply and sewerage lines in single bundles. This precludes the need to dig up roads, which in turn minimizes interruptions to traffic flow and maintains a stable supply of essential utilities when disaster strikes.
Five lines of such conduits measuring 11.2 kilometers in total have been completed in the city of Osaka.
