Client: Vietnam Waste Solutions, Inc.
Main Contractor: JPS Engineering & Construction Company Limited
Project Details:
Da Phuoc Integrated Waste Management Facility is located in Da Phuoc Commune, Binh Chanh District ~ south of Ho Chi Minh City, Vietnam.
Da Phuoc Phase 1 Sanitary Landfill with leachate collection, removal & treatment is designed by Vector Engineering Inc. basing on North American standards and receives up to 6,000 tons of domestic waste daily.
Green Cosmos jointly with our local partner JPS E&C constructed the entire 45ha landfill complete with soil improvement works (PVD), field installation of 1.5mm thick single-side textured HDPE liner and 30/30 kN biaxial geogrids, sub-drain & leachate collection system and uni-axial high strength geogrid reinforced embankment construction – all under strict CQA supervision by Vector Engineering, Inc.
Approximate Quantities
Sub-drain sand : 400,000 cum PVD : 1,180,000 linm Sub-drain pipes : 3,800 linm Biaxial geogrid : 310,000 sqm |
Engineered Fill : 90,000 cum Biaxial geogrid : 310,000 sqm Strip drain : 67,000 linm |
