Do not say correct things in the PDF. I am surprised not to see PDF BD guys have not yet posted many hundred pictures of 5-star hotel and of other areas to prove that Dhaka is the best City in Asia. Many people are like frogs living in water wells without getting any knowledge of the world outside of BD.
Water logging is an engineering issue. It certainly has engineering solutions, although Dhaka is located in a low land. The solution may lie in the construction of a complex system as follows:
- Design and construct a drainage system with proper slopes, width and depth.
- Provide many different discharge points at the rivers like Balu, Buriganga, Turag etc., and to water bodies like Hatir Jheel and Dhanmondi lake. Different discharge points also mean that the city be divided into
many drainage zones depending upon their locations.
- Build pumping stations wherever the depth of a drain goes down too much.
- Build dike/levy along the river banks, so that river water does not inundate the city. Use pumps during rainy season to discharge water from the city to these rivers.
- Build pumping stations, sluice gates and locks wherever needed along the rivers.
I think, the govt should initiate a 20-year master plan to build the drainage system and build it step by step with a well coordinated planning and schedule.
