Beijing has allocated 3.5 billion CNY (580 million USD) to improve drainage on 43 major overpasses in areas prone to flooding.
However experts say that in addition to these improvements, the capital needs to incorporate the underground drainage system into an integrated urban development plan to protect residents during the flooding season.
Lianhua Bridge on the Third Ring Road required the most complex improvement plan.
The Beijing Drainage Group, which is responsible for the work, has built a new pumping station to increase capacity and provided another 180 pipes and four storage ponds that can hold more than 11,000 cubic meters of water.Â
