Station development
City gas plumbing construction had finished safe the day before yesterday, though the worst accident had been in our mind, explosion by some mistake. Engineering plastic is used recently for the big duct connection for quake resistance. This kind of infrastructure construction would be done on electric power supply, water supply and sewerage also from now in accordance with station development. It will take time at least more 10 years from now till the planning would be finished.
