(Central News Agency, reporter Tsai Meng-yi, Kaohsiung, 19th) In preparation for the upcoming flood season, the Kaohsiung City Water Resources Bureau stated today that it has completed inspections of outflow control facilities for 41 development projects throughout the city. Through case-by-case checks, it is estimated that about 750,000 tons of flood detention volume can be provided, reducing the drainage impact caused by land development.
The Kaohsiung City Water Resources Bureau stated in a press release today that, to date, 41 development projects city-wide have completed the installation of outflow control facilities. As development projects increase, the Bureau will continue to conduct inspections and supervision, urging developers to fulfill their maintenance responsibilities to ensure the facilities operate normally and fulfill their flood detention function.
The Bureau pointed out that through pre-flood season inspections and flood prevention checks, an estimated 750,000 tons of detention volume will be available, reducing the drainage impact of land development on the surrounding environment.
Furthermore, in addition to the outflow control plan, Kaohsiung City has other flood control and regulation mechanisms such as "detention ponds, natural lakes, and reservoirs." Among these, there are 26 detention ponds with a storage capacity of about 4.99 million tons, and 5 natural lakes and reservoirs with a storage capacity of about 10.01 million tons, further enhancing the city's overall flood resilience.
The Water Resources Bureau explained that the Water Resources Agency of the Ministry of Economic Affairs has amended the regulations for outflow control applicable to development projects. The threshold for general development projects has been lowered from 2 hectares to 1 hectare, and for new buildings within urban planning areas, it has been lowered to 0.2 hectares. A one-year grace period is provided, and the new rules will officially take effect on September 3rd this year.
The Bureau noted that in the face of challenges from extreme rainfall, it will continue to strengthen the inspection and supervision of outflow control facilities. It calls on responsible parties of future small and medium-sized development projects to properly maintain facilities and cooperate with inspections to jointly expand flood detention and mitigation benefits and enhance urban flood resilience.
