Ho Chi Minh City is considering a $7 million project to construct a substantial underground reservoir beneath the Linh Tay Sports Complex in Thu Duc. The reservoir aims to hold 13,000 cubic meters of rainwater, alleviating severe flooding in the area by reducing submersion of streets after heavy rains. The plan would transform the frequently inundated region by preventing water levels from rising up to two meters.

 

The city’s basin-like terrain, coupled with an outdated drainage system, contributes significantly to recurring floods along vital roads and markets. Situated beneath a football field, the reservoir would span 70 by 50 meters and be 5.2 meters deep, utilizing Cross-wave plastic panels. The comprehensive project also includes a settling pond, pumping system, and necessary drainage components, with the field restored post-construction for recreational purposes.

 

Officials highlight the underground reservoir's multifunctional use of urban space, akin to similar projects in densely populated cities like Singapore and Tokyo. Not only would it reduce flooding, but it also offers potential water storage for firefighting and irrigation tasks. Experts recognize this innovative approach yet caution against the high expenditure and structural complexity involved compared to open reservoirs.

 

Vo Kim Cuong, a former deputy chief architect of HCMC, emphasized the spatial efficiency of subterranean reservoirs beneath existing facilities. Despite their advantages, these projects face high costs and technical challenges, with previous plans for multiple reservoirs delayed due to financial and standardization issues.

 

If approved, the Linh Tay reservoir would substantially surpass the smaller scale project on Vo Van Ngan Street, which was aided by Japan. The city is also pushing for improvements to the Ngoc Thuy canal drainage system, proposing initiatives like dredging and implementing embankment work. Officials aim for a comprehensive strategy that enhances drainage and reduces flood risk across Thu Duc through an array of infrastructure enhancements.

 

Key Takeaways

  • HCMC considers a $7 million underground reservoir to mitigate flooding.
  • The innovative project repurposes space beneath a sports field for water storage.
  • Previous flood-control plans stalled due to funding and technical issues.
