It took how many days before the flood went out. There were questions why Manila was flooded for long days when in fact typhoon Ondoy was on it's way out of the country. A geodetic engineer who is an expert said that it is because of the drainage system of Manila. The people who started the project of wrong drainage system did not consult them. Water can't flow immediately through the rivers like Pasig river because of it's narrow drainage and that's why water was block within the area. He compared Manila as a heart which is having a heart attack that blood flows to a section of heart muscle and blocked. The only solution is having a heart bypass, he said, by making drainage through Manila Bay and/or Laguna de Bay. If another typhoon comes, the flood tragedy will not ever happen again.
