The San Roque Dam is a large dam on the Agno River in the Philippines . The dam is 210 meters high and 1,130 meters long the largest in Southeast Asia and around the twelfth-largest rockfill dam in the world.

The dam project in the province of Pangasinan in Luzon is San Roque Multi-Purpose Dam Project (SRMDP) called. It is used to irrigate 87,000 hectares of land, flood protection and power generation . The reservoir holds about 850 million cubic meters (another source gives 990 million) and is 12.8 square kilometers. It extends as far as Itogon in the Benguet province . A hydropower plant with an output of 345  MW is operated with the stored water .

The dam, which, according to other sources, can also be 200 m high, consists of rubble material. It was built between 1994 and 2004 near San Manuel and San Nicolas 200 km (other source: 500 km) north of Manila . The actual construction work began in May 1998. The normal storage target is 280 meters above sea level, but in the event of a typhoon , the storage system can withstand a storage height of 290 meters. In August 2002, the filling of the reservoir began.

The dam has a flood relief system with six independent closures to prevent overflow of the dam. It was designed for a 100-year flood with a discharge of 12,800 m³ / s. It is 800 meters long, 100 meters wide and overcomes a height difference of 165 meters. From 1999 to mid-2002 it took the necessary soil to be excavated to a stable rock. After that, 530,000 cubic meters of concrete were poured over two years.

The two associated tunnels for water supply and drainage are each over 1200 meters long.

Criticism of the project

The agno has always been considered sacred by the indigenous Ibaloi people of Benguet. The river valley is their cultural heartland and has been home to their farms, houses and small mines for at least 500 years. The San Roque Dam will permanently destroy the home, community and livelihood of the Ibaloi. That is why most of the 35,000 Ibaloi, as well as the Kankanaey and Kalanguya who also live there, are the strongest opponents of the dam. They are also concerned that there will be increased floods and sediment transport in the catchment due to mining activity, flooding their homes and burial grounds and negatively impacting water quality.

So far, more than 600 families have been expelled to make way for the reservoir. Many are struggling to survive in the new settlements in the new quarters and have no land to support them. Another 200 families had to make way for excavation at the dam construction site. They were forced to leave their country. According to the guidelines of the project developer, the Japanese bank Japan Bank for International Cooperation (JBIC), the resettled must receive funds to support themselves, but those affected by San Roque do not have it. The dam should not the recommendations and principles of many things World Commission on Dams match (World Commission on Dams, WCD).

It is planned that the dam will be put into operation after the construction of the San Roque Power Corporation (SRPC) . This company is a joint venture of mainly foreign companies. The whole project is financed by Japanese banks. The terms of the contract are allegedly designed so that the Government of the Philippines bears too much risk and responsibility in relation to the benefits. The Philippine electricity consumer NPC has to pay, it is said, a fixed monthly price of more than 10 million dollars for the provision capacity, regardless of whether electricity is produced or not.
