MANILA, Philippines – The water level in Angat Dam has recorded no improvement since October 8.

In fact, its water reserve receded further by more than two meters from 187.53 meters this morning.

“Halos wala lang talagang pag-ulan doon sa may watershed ( The watershed has had almost no rain at all),” noted Ailene Abelardo, a weather specialist from PAGASA.

According to PAGASA, the watershed needs at least three cyclones to replenish Angat’s water supply and reach its normal operating level of 210 meters.

“Hindi naman kailangang doon mismo yung bagyo kung sakop siya noong cloud rain bands niya na doon ibinubuhos yung malakas (The cyclone doesn’t need to be there as long as the cloud rain bands cover the area),” Abelardo explained.

As an effect, Maynilad announced possible water service interruptions among its customers due to the receding water reserve in Angat Dam and in Ipo Dam.

Thus, the water concessionaire advised its clients to store enough supply of water and monitor the agency’s social media accounts for advisory should they decide to impose low pressure or water service interruptions in the coming days. – MNP (with details from Rey Pelayo)

Due to this, the National Water Resources Board (NWRB) is aiming to cut water allocations. According to NWRB Executive Director Sevillo David Jr., they want to manage the water supply in case the water level will not reach 212 meters by the end of the year.

“In order to manage iyong supply ngayon just in case na hindi ganoon ka-favorable iyong mga rainfall na darating sa Angat watershed (In order to manage the current supply in case there will be no favorable rainfall at Angat watershed),” he said.

According to PAGASA, rainfalls are still expected in Angat Dam area before the end of the year.

“Pagpasok ng November may mga dalawang bagyo tayong inaasahan diyan (By November, we are expecting two more typhoons),” weather specialist Edgar dela Cruz said.

The NWRB said they plan to conduct cloud seeding operation but that will only slightly increase the water level at Angat Dam.

Meanwhile, the NWRB will launch a campaign for responsible water consumption by November.—AAC (with reports from Rey Pelayo)

Monsoon rains have slightly increased the water level in Angat Dam.

Water level rose to 159.85 meters around 6:00 a.m. on Monday (July 1) from 157. 96 meters last Saturday (June 29).

The National Water Resources Board (NWRB) Executive Director Dr. Servillo David. Jr. is hopeful that the water level increase will continue. However, he said it is still too early to announce a continuous recovery since the dam’s water level is still below critical level.

“It’s a positive development kasi may mga pumapasok na mga inflow sa Angat Dam. We are hopeful na mag-continue probably start na ito ng pag-recover ng Angat Dam, (It’s a positive development because there is inflow entering Angat Dam. We are hopeful it will continue and will probably be the start of the recovery of Angat Dam),” he said.

David also said water allocation for the Metropolitan Waterworks and Sewerage System (MWSS) will remain at 36 cubic meter per second while they continue monitoring the recovery of Angat Dam.

“Ang tinitignan natin dito iyong requirement din ng security ng water supply for the rest of the year, in order for us to consider kung mase-secure natin iyong pangangailan sa tubig even sa susunod na taon (What we are looking at is the requirement for the security of water supply for the rest of the year, in order for us to consider if we can secure water demand even foe next year),” according to David.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is expecting two to three tropical depressions next month.

PAGASA Hydrologist Elmer Caringal said these tropical depressions will hopefully aid in the recovery of Angat Dam.

“Malaking tulong din ito doon sa water shed ng Angat Dam kasi itong bagyong ito ang maghahatak ng habagat na posibleng magbigay ng malalakas na pagulan sa water shed ng Angat Dam, (This is a great help for the water shed of Angat Dam because these tropical depression will pull southwest monsoons that will provide heavy rainfall in Angat Dam water shed),” he said.—AAC (with reports from Joan Nano)
