Flooding is a perennial problem in Metro Manila, various flood and drainage system projects have been implemented in Metropolis in the last two decades, but it seems only a little have been gained because the flood problems will persist. Flood control and drainage system has yet effectively address due to the inadequate capacity of existing drainage channels in conveying storm water to the dumping stations.
