Beneath the Under Xikeng Reservoir Viaduct stands a testament to Shenzhen’s intricate water management. This viaduct overlooks a crucial element in the region’s water infrastructure. The city relies on reservoirs like Xikeng to meet its water demands. Shenzhen has no large rivers. It depends on rain-fed rivers and streams. These are small and prone to pollution. They have a weak self-cleaning ability.
The Under Xikeng Reservoir Viaduct offers a unique perspective. It highlights the connection between infrastructure and water resources. Shenzhen has constructed 183 reservoirs. They hold a total storage capacity of 973 million cubic meters. The water surface area totals 81.84 square kilometers. This accounts for about 4.1% of Shenzhen’s land area.
However, Shenzhen faces water scarcity challenges. Its per capita access to water resources is limited. In 2019 it stood at 154.54 cubic meters. This is about 1/13th of the nationwide average. The city depends heavily on external sources. About 85.40% of its water is diverted from the Dongjiang River.
The Under Xikeng Reservoir Viaduct isn’t just a bridge. It is a vantage point. It shows the scale of Shenzhen’s water management efforts. The reservoir plays a vital role. It ensures water supply for the city’s residents and industries.
The viaduct stands as a reminder of Shenzhen’s vulnerability to natural disasters. The city is prone to typhoons and rainstorms. Rainfall is unevenly distributed throughout the year. Most precipitation occurs between April and September. Brief heavy rainfalls and extreme rainstorms are frequent. The multi-year average precipitation reaches 1935.8 mm. The annual average rainfall days number 144.
From here, observe how Shenzhen balances development with environmental concerns. The city has designated 26 water conservation zones. These cover 361.6 square kilometers. This is 33% of the areas within the basic ecological control line. First-grade and second-grade classifications occupy 115.91 square kilometers and 134.49 square kilometers respectively.
The Under Xikeng Reservoir Viaduct provides more than just a crossing. It reveals the story of Shenzhen’s struggle for water security. It is a story of innovation. It is a story of resilience. It is a story etched into the landscape. As you stand here, consider the importance of water. Appreciate the engineering that makes it accessible in this dynamic metropolis. The Under Xikeng Reservoir Viaduct is a unique place to contemplate Shenzhen’s future.
