The Angat Dam and Dyke had been in operation for about three decades when PHIVOLCS (Philippine Institute of Volcanology and Seismology) announced in 2002 that the West Valley Fault (also known as Marikina Fault), is potentially active.  PHIVOLCS  are of the opinion that the West Valley fault runs 200 meters East of the Main Dyke and any movement may affect the local fault.

Considering the often occurrence of earthquake nowadays thus the need to strengthen the Dam and Dyke to ensure its safety. Since the Angat Dam and Dyke safety is indeed a national security concern which needs to be addressed immediately, the urgent need now is to establish immediate contingency measures and remediation works.

The Project was approved by the NEDA Board on 04 September 2012 in the total Project Cost of PhP 5.70 Billion to be funded by the National Government. The Project is ready for bidding, however, in light of the recent Supreme Court decision confirming the validity of the award of Angat Hydro-Electric Power Plant (AHEPP) privatization to Korea Water Resources Corporation (K-Water), discussion is on-going with K-Water regarding the subject strengthening works under the term of its bid to undertake mandatory rehabilitation of Angat Dam.
