Suez, the largest water-treatment company in the world, has entrusted the detailed engineering for the expansion of the Juan Díaz waste water treatment plant (WWTP) in Panama to Ayesa.
This project forms part of an ambitious sanitation programme for the capital and the Panamanian Bay, affected by the dumping of waste and which serves a population that is growing at an annual rate of 2%. The first phase of the Juan Díaz WWTP began in 2009 and once the expansion is complete, the plant’s capacity will have doubled to reach 475,000 cubic metres a day. The current investment stands at nearly 200 million euros.
When the work is finished, the plant will serve two million inhabitants. It is equipped with the latest treatment technology so that the purified water can be discharged into Panama Bay, complying with the national quality standard. Additionally, it is energetically self-sufficient, as it incorporates a biogas production system which uses mud and renewable energy.
Ayesa will carry out the detailed engineering for Suez for all the structures (pre-treatment; biological treatment of mud and odours; the handling of biogas; and electric control rooms) and the Interactive Centre and Environmental Education building.
