Strengthening of the Angat Dam and Dyke in order to ensure its stability and safety to withstand the potential risk posed by possible seismic activity associated with the West Valley Fault.
- Instead of MWSS, the strengthening works of the dam and dyke is being implemented and funded by Angat Hydropower Corporation (AHC), the new Owner/Operator of the Angat Hydro-Electric Power Plant (AHEPP), pursuant to their contract obligation to undertake mandatory rehabilitation of Angat Dam.
However, contract package 2 (dam instrumentation) & contract package 4 (flood protection works) of ADDSP in the total cost of PhP 553.30 Million remains to be the responsibility of the government, thus MWSS, as allowed by the DBM and NEDA, transferred the funds directly to the agency mandated to implement contract packages 2 & 4, which are the National Power Corporation (NPC) and the Provincial Government of Bulacan (PGB), respectively. Corresponding MOAs were executed for the subject transfer of funds and its implementation.
Dam Instrumentation Works = PhP261M
Flood Protection Works = PhP292M
Dam Instrumentation and Flood Protection Works is funded by the National Government in the total amount of PhP 553M
Korea water Resources Corporation (K-Water)
Strengthening Works = Angat Hydropower Corporation (AHC)
Dam Instrumentation and Flood Protection Works = National Government
Status: (as of 30 June 2019)
- Strengthening works:
Construction works 100% completed being undertaken by Hanjin, the contractor engaged by AHC.
- Dam Instrumentation Works:
Five (5) out of the seven (7) contract packages were already completed.
This is being implemented by NPC as per MOA.
- Flood protection works:
Completed as per information from the Provincial Government of Bulacan (PGB). This is being implemented by PGB as per MOA.
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.
