Opened in 1976, the Prima Deshecha Landfill features 1,530 total acres, with 697 acres for waste disposal. The site averages approximately 1,400 tons per day, with a daily maximum permitted tonnage of 4,000. The Prima Deshecha site has a projected capacity to serve residents and businesses until approximately 2067.

In August 2016, the La Pata gap extension opened, consisting of a road build through the landfill property, connecting San Clemente and San Juan Capistrano. Construction of the new road required excavation of 800,000 cubic yards of waste and the installation of tunnels to accommodate landfill vehicles and safe wildlife crossing. The Prima site is also home to a landfill gas-to-energy plant, which powers 7,500 homes and is managed by the Foristar Methane Group.
