MALOLOS
CITY—Recent disasters in the Visayas kept dam operators and local officials in
Bulacan preparing for possible Angat Dam Break.
Liz
Mungcal, head of the Provincial Disaster Risk Reduction Management Office
(PDRRMO) said that before the Bohol earthquake struck, they have been meeting
with dam operators.
This
includes operators of the Angat, Ipo and Butos Dam, along with officials of the
Metropolitan Waterworks and Sewerage System (MWSS), and the Common Purpose
Facilities (CPF).
“We
have to prepare in anticipation for disaster that will be brought by possible
break of the Angat Dam,” said Muncgal in the sidelines of the meeting of members of the Angat Dam break technical working group at the La Mesa Dam in Novaliches, Quezon City
on Tuesday, November 12.
Mungcal
noted that Angat Dam break can occur anytime if
case of movements in the Marikina
West Valley Faultline (MWVF).
The
same was echoed by members of the TWG who noted that the disaster woild be
unimaginable.
To
prepare for such possibilities, Mungcal said the provincial government in
coordination with the National Power Corporation (Napocor) and the Engineering
Development Corporation of the Philippines (Edcop) had prepared an emergency
action plan (EAP).
The
said EAP will be presented to Bulacan and Pampanga mayors and disaster officers
next week.
Some
of the inputs on the said EAP is the establishment of early warning system
(EWS), evacuation routes and possible mass evacuation center.
Some
of the evacuation areas identified are located in the upland areas of Bulacan,
Pampanga and Nueva Ecija.
Based
on simulation study conducted by Tonkin & Taylor International and Edcop, a
wall water rising to 10 to 30 meters will rush out into the Angat River within
hours in case of a dam break.
The
said on rush of water is said to wipe everything on its path that will make
damages left by earthquake in Bohol and typhoon Yolanda in Visayas as a thing
of the past.
Disaster
officials said that it will initially damage Bulacan, but the long term effect
will be in Metro Manila which will ran out of water for months.
This
is due to the fact that Metro Manila is drawing 97 percent of its potable water
requirement from Angat Dam. Dino
