DPWH sets rules for river dredging

Public Works and Highways Secretary Rogelio Singson has issued Department Order 139, which sets the rules for all river dredging activities for flood-control and quarrying.

Under the new rule, possible ecological damage can now be avoided as all projects now need a series of soil investigation and analysis, which include actual on-set bathymetric and the topographic and hydrographic surveys (in accordance with the department’s Design Guidelines Criteria and Standards).
