The Department of Environment and Natural Resources has ordered the National Mapping Resource and Information Authority, one of the DENR’s attached agencies, to prepare maps that will help identify the esteros or canals that dispose of wastewater directly into Manila Bay. The maps will be used in the rehabilitation of the bay, DENR Secretary Roy Cimatu said in a news conference in Quezon City yesterday. “We have to start early. We have to hit the ground running since Manila Bay’s cleanup will be a difficult task,” Cimatu said.
