Department of Environment and Natural Resources (DENR) Secretary Roy A. Cimatu (3rd from left) checks on the map of Calumpit River with DENR Region 3 Executive Director Paquito Moreno, Jr. (2nd from left) during the recent visit of the former in Bulacan . The more than eight-kilometer river will be desilted and grubbed of waste materials to reduce flooding of low-lying areas in the region. The Calumpit River is a tributary of the larger Pampanga River, and the town of Calumpit is a natural catch basin for flood waters coming from Nueva Ecija and Pampanga. The massive cleanup will hasten the rehabilitation of the Manila Bay areas in Central Luzon. ###
