Dear Drainage Services Department,
I would like to ask whether there are any measurement data of outfall discharge of storm water drainage system. Such kind of data is valuable for learning about the capacity of the drainage system, espacially duirng some extreme weather events such as super typhoon. Is it possible for DSD to provide some measured data of outfall discharge of the drainage system (best hourly data) during historical typhoons for reseach purpose?
I refer to your application for access to information dated 17 February
