Angat Dam water nears critical level

The water elevation in Angat Dam is now nearing critical level, based on the monitoring of the Hydrometeorology Division of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).

As of 6 a.m. Thursday, Angat Dam’s water level was at 160.73 meters which is lower than Wednesday’s 161.30 meters.

The water at the Angat dam has reached critical level on Thursday morning, based on the monitoring of the Hydrometeorology Division of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).

As of 6 a.m., Angat Dam’s water level was at 160.73 meters down from Wednesday’s 161.30 meters.

Angat dam supplies water to Metro Manila and Central Luzon areas. If its water level drops to the critical level of 160 meters, the supply for domestic use will be slashed.

The National Water Resources Board earlier said that when Angat Dam reaches the critical mark, the allocation for the Metropolitan Waterworks and Sewerage System (MWSS) will be adjusted again to give way to the shutting down of the auxiliary unit.

The NWRB said at least 36 cubic meters per second (cms) will be allocated for the MWSS until the dam further declines to 150 meters if there is no significant inflow in the coming days.

The agency warned this will mean longer water service disruption, and will have considerable impact on the normal delivery of services of concessionaires in Metro Manila and Bulacan.

Concessionaires Maynilad and Manila water have already announced rotational water service interruption schedules in their respective areas.

Last June 18, the NWRB reduced the water allocation for Metro Manila from 46 cms to 40 cms in preparation of the Low-Level Outlet (LLO) as a back-up water discharge and to lessen the effect of limited water supply in the coming days.

The agency continues to appeal to the public to conserve and use water wisely.

Angat dam water level goes up but still below target – NWRB

MANILA, Philippines – The water level at the Angat dam continues to go up, according to the monitoring of the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

As of 6 a.m. Tuesday (December 17), the Angat dam’s water level is at 197.22 meters, which is higher than the 196.67 meters recorded on Monday.

PAGASA said this is due to the rainfall brought about by the recent Typhoon Tisoy (international name: Kammuri) and the effects of the northeast monsoon (Amihan).

The state weather bureau said water levels at the Angat dam usually improve at this time of the year based on historical data.

Despite this, the National Water Resources Board (NWRB) advised the public to still conserve and use water wisely.

NWRB executive director Servillo David Jr. said this is because the target normal operating level of 212 meters for Angat Dam has yet to be reached.

Angat Dam supplies water to Metro Manila and Central Luzon areas.

“Nag-i-improve siya pero ang sabi nga namin ‘yung improvement niya hindi natin masasabing okay na tayo para maging business as usual tayo sa paggamit natin ng tubig. We’re not out of the woods yet,” David said.

“Sabi nga natin, mas mababa siya kumpara sa mga nagdaang taon,” he added.

David warned that water consumers may again experience supply shortage in the next dry season if the normal operating level at Angat dam will not be hit by the end of the year.

“Kapag hindi po kasi siya naka-recover dun sa target natin na 212 meters, then magkakaroon ng impact ito sa water supply natin particularly for the Metro Manila residents at kasama na rin yung sa irrigation which is around 27,000 hectares sa Bulacan at Pampanga,” he said.

“Baka magpapatuloy po, most likely ay magpapatuloy ang kabawasan sa suplay natin sa tubig,” he added.

Parts of Metro Manila and nearby areas are still experiencing rotational water interruption due to insufficient supply.

According to PAGASA, the water level at Angat dam may only reach 200 meters even if the northeast monsoon prevails until February next year.

The state weather bureau has not monitored any weather disturbance that may develop into a tropical cyclone outside the Philippine area of responsibility. – RRD (with details from Correspondent Joan Nano)

Maynilad, Manila Water rate to spike in 2020

Maris Federez   •   December 6, 2019

MANILA, Philippines – Manila Water and Maynilad Water Services will affect a rate hike in January 2020.

This is at the height of President Rodrigo Roa Duterte’s directive to review the contract between the government and the two water concessionaires. 

Maynilad and Manila Water will implement around P3.00 per cubic meter price hike.

Add to this is the increase in the Foreign Currency Differential Adjustment (FCDA) and other foreign currencies that the two water concessionaires use in their loan payment.

In 2018, the Metropolitan Waterworks and Sewerage System (MWSS) has approved Maynilad and Manila Water’s rate increase petition.

For Maynilad, the approved rate hike is P5.73 which will be applied on a staggered basis for five years or until 2022.

Manila Water, on the other hand, had been allowed a rate increase of P6.22 to P6.50.

Meanwhile, with the expected rate hike, water service interruption will still be experienced by Maynilad and Manila Water consumers as the National Water Resources Board (NWRB) has yet to increase Metro Manila’s water allocation despite the rising water level in Angat Dam.

As of Friday morning, the water level in Angat Dam was at 195.03 meters.

This, however, is still far from the dam’s normal operating level of 210 to 212 meters.

Authorities advise the public to continue to conserve water to maintain sufficient water supply in Angat Dam until the next dry season. (from the report of Harlene Delgado) /mbmf

‘Tisoy’ exits PH, leaves more water in Angat Dam

Marje Pelayo   •   December 5, 2019

MANILA, Philippines – Typhoon Kammuri local name ‘Tisoy’ exited the Philippine area of responsibility (PAR) on Thursday at 8:00 AM, according to state weather service PAGASA.

Based on PAGASA’s latest update, ‘Tisoy’ was located at 580 km south of Iba, Zambales.

Though the weather disturbance no longer impacts any part of the country, scattered rains and thunderstorms will still be experienced in Cagayan Valley, Cordillera Administrative Region,and the province of Aurora due to the effects of the tail end of a cold front.

Meanwhile the Northeast Monsoon will bring light rains over Ilocos Region and the rest of Central Luzon.

Metro Manila and the rest of the country, meanwhile, will have partly cloudy to cloudy skies with isolated rainshowers due to localized thunderstorms.

According to PAGASA, Typhoon Tisoy somehow improved the water level in Angat Dam.  

As of 6:00 AM today, Angat’s level marked 1.05 meter-increase to 194.52 meters from Tuesday’s 193.47 meters.

Prior to that, Angat Dam gained more than 4 meters during the onslaught of the typhoon. – MNP (with details from Rey Pelayo)
