Scope of work/supply: Turnkey contract for design, fabrication, supply, assembly, installation, testing and commissioning of three treatment plants. The plant capacities total 8 MGD. The Reverse Osmosis treatment plants will use brackish groundwater previously thought to be unsuitable for public consumption. Using this alternative water source reduces the local dependence on surface water from the Rio Grande River. Doosan contracted directly with the plant owner to provide the full turnkey installation of these plants, allowing for one central point of responsibility.
