Acciona has been constructing the ‘La Pradera’ pumping station for the future Wastewater Treatment Plant (WTP) at Las Esclusas, in the city of Guayaquil since mid-2017. After almost a year, the building work is 55% completed and the plant is expected to be commissioned in the first semester of 2019.
The project, awarded to Acciona by the Municipal Company of the Potable Water and Drainage System of Guayaquil, will help to modernize the present wastewater treatment network of Ecuador’s biggest city through a program called ‘Universalization of the Sewerage Network’ for the benefit of one million people who live between the center and the south of the city, almost one-third of its residents.
The new pumping station will be able to deal with water flows of up to 6.4 cubic meters per second. The structure that will house the equipment has 26-meter-deep walls, and the digging and construction of the slabs to be placed at the bottom have already been completed.
The main equipment is currently being manufactured. It includes 7 vertical centrifugal pumps, odor control systems and valves and cranes, among others. The new station will be powered from a substation that is under construction, including a transmission line around 1 kilometer long that will connect the substation and the pumping station.
La Pradera has been financed by the European Investment Bank and will be constructed by ACCIONA through its subsidiary Acciona Agua under the turnkey formula. The total estimated investment for the project is 22 million dollars (around 20 million euros).
