DENR to conduct nationwide waterways dredging project, evaluates Laguna Lake

MANILA, Philippines – Environment Secretary Roy Cimatu wants an immediate assessment of the major waterways like rivers across the country to determine which of them needs to undergo dredging.
Environment Undersecretary Jonas Leones said the Department is planning a dredging operation in the Cagayan River which carries water from Nueva Ecija to Appari.
The recent onslaught of Typhoon Ulysses caused the river to overflow its banks and submerge nearby areas like Cagayan and Isabela.
In his last briefing with President Rodrigo Duterte, Cimatu said the government will not shell out any amount for the project but it will gain from it instead.
“It will be really a request of the governor to allow a contractor to clean or to dredge the river and at the same time in exchange of that, he has allowed to sell this sand,” Cimatu said.
“But they have to pay as much as what the mining company is paying for – 4% excise tax as a revenue of the government,” he added.
Meanwhile, the Laguna Lake Development Authority (LLDA) is studying the proposed plan to rehabilitate the lake.
According to the agency, the Laguna Lake is now about 2.5 meters deep as compared to 5 meters that the locals used to observe in the past.
According to LLDA Department Manager III Emeterio Hernandez, they have to remove at least 2 meters of sediments or silt from the lake, especially at the opening section and the western section to make space for water flowing from nearby waterways like Marikina River.
“Ang ibang common term dyan is parang batya na sinasahod niya lahat ng ulan na nanggagaling sa ating mga watershed,” Hernandez said.
[The common term for that is like a basin that catches the rain coming from the watershed.]
“So kung ang batya natin ay medyo mababaw na, so ineexpect natin na kaunting dagdag lang ng tubig mag ooverflow siya,” he added.
[So if the basin becomes shallow, with only a small amount the water will overflow.]
No government funding will be required for the dredging operation, Hernandez said.
Once approved, the project is expected to commence next year and will be completed hopefully within the next 3 to 5 years. MNP (with reports from Rey Pelayo)
