Underground pipelines to be upgraded
China will upgrade old and massive underground urban pipelines in five years to reduce potential risks in expanding cities.
The massive pipelines running underground play a major role in urban development, carrying the water, sewage, gas, electricity, telecommunications, cable signals and other necessary supplies for daily life as well as industrial production.
With the rapid urbanization in China, larger cities with fastgrowing populations witnessed more accidents with severe economic losses and casualties.
An explosion in a gas line in Qingdao, Shandong province, in November killed 62 people and injured 136. Leakage in a petrochemical pipeline contaminated the water supply in Lanzhou, Gansu province, in April. On May 11, a torrential rain hit Shenzhen, Guangdong province, flooding more than 2,500 roads in the city and causing an economic loss of about 80 million yuan ($12.9 million).
