Wawa Dam (also known as Montalban Dam)[1] is a gravity dam constructed over the Marikina River in the municipality of Rodriguez in Rizal province, Philippines.[2] The slightly arched dam is situated in the 360-metre (1,180 ft) high Montalban Gorge or Wawa Gorge,[3] a water gap in the Sierra Madre Mountains, east of Manila. It was built in 1909 during the American colonial era to provide the water needs for Manila.[4][5] It used to be the only source of water for Manila until Angat Dam was built and Wawa was abandoned. Due to insufficiency of water supply for Metro Manila, there was a strong clamor to reuse the dam.[6]
