Payatas dumpsite

Originally established in the 1970s,[1] the former open dumpsite was home to scavengers who migrated to the area after the closure of the Smokey Mountain landfill in Tondo, Manila.

[2] After the Payatas landslide happened in 2000,[3] the newly passed Ecological Solid Waste Management Act mandated the closure of open and controlled dumpsites.

[2] People residing in the Smokey Mountain landfill in Tondo, Manila who worked as scavengers migrated to the Payatas dumpsite after the former's closure in 1995.

[2] On July 10, 2000, the Payatas landslide caused the deaths of 232 people residing within the landfill,[3] which prompted the passage of Republic Act No.

[3] In 2000, a geologist from the University of the Philippines raised that there might be a possible leakage of leachate from the dumpsite to the La Mesa Dam and Reservoir.
