The National Water Resources Board (NWRB) said lower water allocation will last until June.

READ: Angat Dam water level drops further to 159.43 meters

The NWRB has recently announced that they will further reduce the water allocation to 36 cubic per second after the water level in Angat Dam dipped lower than the critical level of 160 meters.

On Monday (June 24), officials of the Angat Technical Working Group agreed to maintain the low water allocation until June.

“At least for the month of June, although we monitored a low pressure area but this might not bring significant rainfall within Angat water shed,” NWRB Executive Director Dr. Sevillo David Jr. said.

The NWRB also estimates that water level might dip to 157 meters which will be the lowest in history.

Meanwhile, the group Bukluran ng mga Manggagawang Pilipino has called on the government and water concessionaires to limit the use of water in several facilities and business establishments such as watering of golf courses and filling up swimming pools.

However, several businessmen, like the resort and function hall in Malate, Manila, oppose this idea.

According to Adora Espiritu, the admin officer of the said resort, they have already reduced the frequency of water replacement in their swimming pools due to the limited supply.

“Hindi kami masyadong nag a-accept ng events ngayon gawa ng water shortage. Kung dati po once a month, gagawin naming once every two months iyong sa chlorine and sa vacuum. (We don’t accept events for now due to the water shortage. Instead of using chlorine and vacuum once a month like before, we’ll just do it once every two months), she said.

Meanwhile, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) confirmed that there will be rainfall at the Angat shed this week which is seen to increase water level.

PAGASA also explained that it will take four months of rainfall to fill the water level in Angat Dam to 180 meters. This is the normal operating level of Angat Dam.

“Kung magkaroon tayo ng significant rainfall for July which is in a period of 1 or 2 weeks then paunti-unti na pong dadami ang recharge, (If we have a significant rainfall for July which is in a period of 1 or 2 weeks of rainfall, then water level will increase),” said PAGASA’s weather specialist, Junie Ruiz.—AAC (with reports from Joan Nano)

Angat Dam water level further dropped from the 160-meter critical level.

From the water level of 159.78 meters last Saturday morning (June 22), it slightly dropped to 159.43 meters as of 6:00 a.m. on Sunday (June 23).

Due to this the National Water Resources Board (NWRB) said they will again reduce water allocation in Metro Manila to 36 cubic meters per second (cms).

Customers of water concessionaires in Metro Manila will have to experience longer water supple interruptions.

Maynilad posted on Facebook their advisory on water interruption schedule in several areas. Some of these places will experience water interruption for as long as 15 hours. Manila Water on the other hand can take up to 17 hours.

Both water concessionaires said they will continue implementing water interruptions while waiting for rains that can resolve the problem in Angat Dam.

According to the NWRB, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has reported that there will be possible rains at Angat Dam by July.

“Base po sa latest projection ng PAGASA ngayong July magkakaroon po ng ,ga significant rainfall sa Angat Water shed but we are hoping that in July dating po ng mas maaga iyan para po, makapabalik na makapag-recharge iyong tubig sa Angat Dam at mag-increase na iyong level (Based on the latest projection of PAGASA this July, there will be a significant rainfall in Angat Water shed but we are hoping that it will come earlier so the Angat Dam can recharge and increase its water level),” according to NWRB Executive Director Dr. Servillo David Jr.

PAGASA estimates that two to three typhoons are needed to fill the Angat Water shed.—AAC (with reports from Joan Nano)

NWRB further reduces MM water allocation as Angat Dam runs dry

by Marje Pelayo   |   Posted on Saturday, June 22nd, 2019

MANILA, Philippines – Metro Manila residents will have to race each other for water rations as taps may dry out due to the continues drop in Angat Dam’s water level.

According to NWRB Executive Director Sevillo David, the reduction of water allocation for Metro Manila from 40 cubic meters per second to 36 cms. takes effect today Saturday (June 22).

As of 6:00 a.m. Saturday (June 22), Angat Dam’s water level has dropped further below critical mark by 0.50 meters to 159.78 meters from 160.28 meters on Friday.

David confirmed that if Angat’s water reserve dips further at the rate of 0.50 meters per day within the next five days, it will break the lowest level recorded at 156.57 meters in July 2010.

On June 18, the NWRB reduced the water allocation for Metro Manila from 46 cms to 40 cms to lessen the effect of limited water supply in the coming days.

Nevertheless, state weather bureau PAGASA’s weather specialist Chris Perez said some parts of the country including Metro Manila may expect rains next week.

“Possible po kasi na mid next week hanggang weekend may mga pagulan (Rains are possible by mid next week until weekend) over some parts of Central and Southern Luzon and Visayas because of a possible habagat episode,” Perez said.

Water storage urged as Angat Dam’s reserve dips near critical level

by Marje Pelayo   |   Posted on Monday, June 17th, 2019

MANILA, Philippines – Water level in Angat Dam is nearing critical level, according to the National Water Resources Board (NWRB), despite state weather bureau PAGASA’s announcement of the onset of the rainy season last Friday (June 14).

Thus, customers of Manila Water and Maynilad are advised to store water in the days to come in preparation for possible water problems.

“We wanted to clarify na sa ngayon hindi pa ganuoon ka-komportable ang sitwasyon kung ang pinaguusapan natin ay ang suplay ng tubig sa metro manila,” explained NWRB Director Sevillo David Jr. said.

(We wanted to clarify that we cannot be that comfortable with the current situation in terms of water supply in Metro Manila.)

“Kasi po sa ngayon is way below normal po and natatanggap nating tubig sa Angat Dam,” he added.

(It is because the (water supply) we receive for Angat Dam is still way below normal.)

As of 6:00 a.m. Monday (June 17), Angat Dam’s water level is at 162.39 meters, only about two meters high that its critical level of 160 meters.

According to the NWRB, Angat Dam can still supply the water requirements to Metro Manila, Cavite, Rizal, and Bulacan even with only 160 meters to 155 meters water reserve.

However, the public will have to work on a very limited supply of water if that happens.

The NWRB said Angat Dam’s reserve may dip up to 155 meters if rains will be scarce until the third week of July.

PAGASA said the El Nino phenomenon may persist up to October this year and the only way to increase water level in Angat Dam is through the entry of tropical cyclones.

“Actually, itong mga dams naman natin talagang mapupuno ito. Two to three bagyo lang puno na iyan (Actually, two to three cyclones are enough to fill our dams),” said DR. Esperanza Cayanan, Chief of PAGASA Weather Forecasting Division.

Maynilad and Manila Water started implementing low pressure to no water during peak hours to their customers since last week.

But if Angat Dam’s water level reaches the critical level, the water concessionaires will opt to implement water service interruptions during peak hours.

The water distributor assured, however, that they will give their customers enough time to store water for their domestic needs prior to service interruptions.

“When that happens na mareach natin ang 160 meters sa Angat Dam then we would have to implement officially this time yung rotational service interruptions na and it will be implemented mararamdaman during peak hours,” said Jennifer Rufo of Maynilad.

(When that happens that Angat Dam reaches 160 meters, we would have to implement officially the rotational service interruption during peak hours.)

“Ang standing order namin is as much as possible gawin natin sa gabi. Pero siguro may mga pagkakataon yung ibang ibang areas depending on the design of the distribution network may ibang tatamaan na during peak,” said Ferdinand Dela Cruz of Manila Water.

(Our standing order is to implement it as much as possible in the evening. But there would be instances in some areas depending on the design of the distribution network that the interruptions would be during peak hours.)

If Angat Dam’s water level reaches 155 meters this year, it will be the lowest in history according to the NWRB as compared to 157 meters, the lowest recorded in 2010. (with reports from Joan Nano)
