MWSS conducts an Executive Briefing of the Angat Dam & Dyke Strengthening Project (ADDSP) for the President on 22 July 2015 at the Angat Dam in Norzagaray, Bulacan. The President was guest of honor and delivered the keynote speech. Other officials who graced the occasion were DPWH Secretary Rogelio Singson, DOF Secretary Cesar Purisima, Bulacan local officials led by Gov. Wilhelmino Sy- Alvarado, PMS head Julia Abad, San Miguel head Ramon Ang, K-Water officials and Manila Water Group head Geodino Carpio.

The Project involves the strengthening of the Angat Dam and Dyke to withstand the potential risk from possible seismic activity of the West Valley Fault (WVF). A splay/local fault of the WVF lies 200 meters east of the Angat Main Dyke. The Dam is located in Barangay San Lorenzo in Norzagaray, Bulacan.

With the PHIVOLCS pronouncement on the dangers posed by the WVF, the MWSS initiated and signed a Memorandum of Agreement (MOA) on October 2011 with PSALM, NPC, NIA, PHIVOLCS, PAGASA, OCD and the Province of Bulacan to identify, prioritize and implement a project that will ensure the safety and reliability of the Angat Dam and Dyke from geological and hydro-meteorological hazards.

Immediately after the MOA signing, a Safety Study was undertaken and the results of the study recommended, among others, the strengthening of the Angat Dam and Dyke and the construction of an auxiliary spillway to accommodate the updated Probable Maximum Flood (PMF) of 12,000 cms, giving birth to the Angat Dam and Dyke Strengthening Project (ADDSP, the “Project”).

The Project with a cost of Php 5.719B was approved by the NEDA Board on 04 September 2012 after which the bidding documents were prepared for implementation by MWSS. However, in the light of the Supreme Court decision on 09 October 2012 declaring the award of the Angat Hydro-Electric Power Plant (AHEPP) to Korea Water Resources Corporation (K-Water) – now known as Angat Hydropower Corporation (AHC) – as valid and legal, the implementation of the ADDSP was handed over to K-Water.

With the decision, MWSS held discussions with K-Water leading to the resolution of all remaining issues regarding the transfer of the implementation of the project to AHC (formerly K-Water).
