Zero absorption equals floodsLast Monday, I passed by the San Francisco del Monte district in Quezon City, and I was surprised that the Grab driver took a different route, avoiding the road along a creek. Imagine how much worse the situation would have been if San Miguel Corporation had not voluntarily undertaken the river dredging and clean-up of the Pasig River system, Tullahan River, Bulacan River system, San Juan River, as well as the San Isidro River in San Pedro, Laguna. According to published data of SMC, the Pasig River clean-up was 26 kilometers long and produced 1,185,207 metric tons of waste and silt. The Bulacan River system was 70.36 kilometers in length and had 4,041,523 metric tons of waste and silt removed by SMC. The perennial headache Tullahan River is 10.9 kilometers with 1,124,183 million metric tons.
