The La Mesa Dam and Reservoir is an earth dam in Quezon City, Philippines. Its reservoir can hold up to 50.5 million cubic meters (1,780 million cubic feet), occupying an area of 27 square kilometers (10 sq mi). It is part of the Angat-Ipo-La Mesa water system, which supplies most of the water supply of Metro Manila.
The La Mesa was built in Novaliches, which was then still part of the municipality of Caloocan due to the sloping topography of the watershed area from Bulacan. The La Mesa dam later became part of a larger dam system with the opening of the Ipo Dam in Norzagaray, Bulacan in 1936, the Angat Dam in the same locale in 1967. The three dams formed part of the Angat-Ipo-La Mesa water system.[1]
The La Mesa Dam was raised in 1959 to increase the reservoir's maximum capacity to its current level.[2]
Damedit
The La Mesa Dam is an earth dam with a height of 24 meters (79 ft). The elevation at its crest is 82.5 meters (271 ft) while the elevation at its overflow section is 80.15 meters (263.0 ft).[3]
Reservoiredit
The La Mesa Reservoir has a maximum capacity of about 50.5 million cubic meters (1,780 million cubic feet). Water from the reservoir spills into the Tullahan River which transports the water to Manila Bay.[1]
The La Mesa Dam is part of the Angat-Ipo-La Mesa water system which supplies water to the population of Metro Manila and surrounding provinces.[1]
The water collected in the reservoir is treated at the La Mesa and Balara Treatment Plants. The La Mesa facility has a design capacity of 2,400 million litters per day (mld) while the Balara facility has a capacity of 1,600 mld. The La Mesa treatment facility serves the western half of Metro Manila while the Balara facility serves the eastern portion of the metropolis.[4]
Whenever the water level of the dam drops below 69 meters (226 ft) or the critical mark, the MWSS, Maynilad, and Manila Water begin to regulate the water supply they dispense to their patrons.[1]
