When a sharp decline in water quality threatened to cause a public crisis in Jordan's capital city, CDM, USAID, and the Water Authority of Jordan responded immediately to complete treatment plant modifications on a design-build basis as quickly as possible. The fast-track schedule, which demanded completion in roughly half the time of a conventional approach, meant procuring equipment within 3 weeks of the project start, beginning construction at the 60-percent design stage, and adapting as work progressed.
One of CDM's first steps in the $5 million project was to install an interim potassium permanganate chemical feeder at the Deir Alla pump station. Its operation improved water quality almost immediately. The team then implemented plant upgrades, including the construction of a new chemical feed complex with permanent potassium permanganate and chlorine dioxide systems. Other improvements included adding variable frequency drives and installing 2,000 square meters of hypalon baffles in the raw water reservoir.
