A backhoe dredges decades worth of silt in Manila Bay

MANILA, Philippines — Using the newest machinery, the Department of Public Works and Highways (DPWH) began on Tuesday (March 5) the wide desilting activity in Manila Bay as part of its rehabilitation.

The DPWH will first work on the 1.5-kilometer area from Manila Yacht Club Breakwater to the US Embassy.

It was divided into five sectors, with each part estimated to take three months to clean.

Desilting is a process of removing waste and mire underneath the seabed of Manila Bay. The waste collected by the amphibious trucks will be dried and segregated.

The collected waste will be taken to Navotas landfill while the mire and soil will be dumped in a land in Bicutan, Taguig to check if it can still be used.

DPWH Secretary Mark Villar said they are targeting to dredge around 225,000 sq. meters for this year.

“Kailangan ding i-analyze ang composition ng ide-dredge namin depende kung ano iyong toxicity kung meron man (We also need to analyze the composition of what we are going to dredge, depending on the toxicity if there is any),” Villar said.

Villar also said that the DPWH will assign 50 personnel every day to work on the desilting and dredging activity in Manila Bay.

They will also use a sewer inspection camera to determine which establishments are spewing waste into Manila Bay.

“Malaking tulong ito. Pagpasok niya sa culvert ng mga pipes tapos mayroong unathorized na pumapasok doon na mga tubo coming from non-compliant, nakikita ito. Kapag nakita niya iyan, ime-measure namin kung saan galing, anong building o anong tubo (It will be a great help when it enters the culvert of the pipes because it can detect unauthorized pipes coming from non-compliant establishments. We’ll be able to determine which building or pipe it is),” he said.

The department also estimates that it would take three years to thoroughly clean the Manila Bay seabed. —Aileen Cerrudo (with reports from Joan Nano)

Another coral garden discovered in Maragondon, Cavite

Marje Pelayo   •   June 21, 2021

MANILA, Philippines — The country has yet another natural treasure discovered in the waters of Cavite that is connected to Manila Bay.

Members of the Philippine Coast Guard (PCG) and volunteer divers were having a clean up drive, “scubasurero” and seagrass monitoring activity in Barangay Patungan in Cavite when they accidentally discovered another coral garden coinciding with the celebration of World Environment Day.

“Recently lang po last June 5, na-discover din po namin na meron din pong coral garden sa Cove ng Barangay Patungan sa Maragondon,” said Andrea Panganiban of the Provincial Environment and Natural Resources Office (PENRO) Cavite.

Panganiban said the Department of Environment and Natural Resources (DENR) is currently conducting an assessment on the said coral garden.

On June 15, PENRO Cavite held another “scubasurero” activity in Maragondon and Ternate in Cavite where they installed marker buoys within the area covering the newly discovered coral garden and within the Maragondon Fish Sanctuary.

It can be recalled that on May 17, over 169 square kilometers of coral garden was discovered at the core zone of Ternate Marine Park within the vicinity of Barangay Sapang Uno and Barangay Bucana.

“Ang nangyari po noon, kami po ay nasa project na maglalagay ng marker buoys para palatandaan kung hanggang saan po ang boundary ng ating core zone upang mabigyan ng impormasyon ang ating mga mangingisda na hindi sila pwedeng pumasok doon. Then kasama po natin sa paglalagay ang mga volunteer divers po natin na gusto nilang makatulong sa pagdodokumento ang proseso po ang ating proyekto,” Panganiban said.

“Nung natapos po natin iyon, nag-scout sila sa ilalim ng dagat. At ayun nga po nadiscover na meron pa tayong napakagandang coral garden sa core zone natin,” she added.

The coral garden measures about 20 meters away from the shoreline of Caylabne and approximately 26 meters in depth.

These new discoveries will contribute greatly to the province’s tourism industry.

“Kasi kung io-open po ito as diving site at kung i-offer po ito as a tourist destination ng management board, magkakaroon po ito ng magandang epekto. Malaki pong potensyal ang lugar pag na-open po siya sa turismo. Magkakaroon po ng pagtaas ng pagkita ng mga mamamayan doon aside from that matutulungan po ang ating community ng fisherfolk na kumita na hindi na nila kailangan magextract sa dagat.” Panganiban noted.

“Posible rin na mabawasan ang mga ilegal fishing sa area dahil sila na mismo ang mangangalaga sa lugar dahil iyon ay pinagkakakitaan na nila,” she added.

PENRO Cavite calls on the public to properly manage disposal of waste in their areas to prevent water pollution.

“Sa lahat ng mga mamamayan na nakapaligid po sa Manila Bay, isakatuparan lang po natin ang tamang pagtatapon ng basura dahil ang basura po na nagmumula sa taas yan po ay napupunta sa dagat,” Panganiban said.

“Kahit po mga simpleng pagtatapon ng balat ng candy, malaking katulungan po iyan sa atin na hindi na mapupunta pa sa dagat,” she added reminding the public to observe safety health protocols to fully experience safe and fun travel in the new normal.

DENR calls on sea vessel owners to explain dumping of waste in Manila Bay

MANILA, Philippines — The Department of Environment and Natural Resources (DENR) will summon the owners of sea vessels that dock at the Navotas Fish Port in Baseco, Manila through the Anti-Pollution Task Force.

The DENR, along with the Philippine Coast Guard (PCG), conducted an inspection at the Navotas Fish Port on Friday (June 4) to check for metal content, fecal coliform, and grease present in the water.

According to DENR Usec. Benny Antiporda, several sea vessels docked at the Fish Port are dumping waste in Manila Bay.

Antiporda said the department will summon the concerned individuals to explain the issue.

“We will talk to them immediately after this kasi ipasu-summon natin sila sa Anti-Pollution Task Force para magkaroon ng dialogue between sea vessels and the government,” he said.

According to the captain of one of the cargo vessels, Angelito Balitaan, there are instances that they would throw waste in Manila Bay because their vessel does not have a sewage system and they do not have enough funds for sewage repairs.

“Starting na natuto ako nang ganiyan iyan na kinagisnan ko, minana na din iyan wala pang implementation ng mga sewage sewage,” he said.

Meanwhile, the test results of the water samples will be released in a week.  AAC (with reports from JP Nuñez)

CAGAYAN, Philippines — The dredging of the Cagayan River is set to begin on February 2, according to the Department of Public Works and Highways (DPWH).

The government aims to remove the sandbars along the narrow area of the river to prevent severe flooding in the Cagayan Valley.

The DPWH said the three sandbars cover around 235 hectares and a volume of seven million cubic meters. They are located in Magapit Narrows which the DPWH noted as a constriction point in the center of the Cagayan River.

The sandbars are specifically located in Barangay Bangag in Lal-lo and in Barangay Casicallan Norte and Dummun in Gattaran.

The DPWH will coordinate with other agencies to speed up the process of dredging the river. AAC (with reports from Grace Doctolero)
