The Regional Government of Andalucía awards Befesa the contract to condition Jerez de la Frontera Wastewater Treatment Plant (WWTP)

Empresa de Gestión Medioambiental, S.A (Egmasa), responsible for management and execution of water supply and treatment works in Andalucía, has awarded Befesa the more than nine million euro contract to execute the expansion and upgrading works at Jerez de la Frontera (Cádiz) Wastewater Treatment Plant (WWTP).

Jerez WWTP treats all wastewater from the towns of Jerez, Guadalcacin, Estella, Los Albarizones, La Corta, and El Portal, prior to their discharge into the river Guadalete. Given the environmental importance of the river and as part of the river recovery works, the awarded works will improve final quality of the discharge, in preparation of the foreseeable declaration of the river Guadalete as a "sensitive area", by conditioning the WWTP to the demandable discharge parameters for these types of areas.

The sizing of the work has been based on a population equivalent of 525,000 and an average daily flow of 70,000 cubic meters. The project includes the implementation of an advanced biological process capable of eliminating nitrogen and phosphor. Of note is the enormous flexibility with which this biological process has been planned as different reaction chambers have been designed and fitted with the necessary elements to allow each one to operate as an anaerobic, anoxic and oxic reactor. During the course of the upgrading works, the plant will continue to operate to ensure prevention of non-treated wastewater discharge into the receiver channel.

This project will benefit a population of more than 250,000 and will be added as a reference to the vast experience Befesa has already accumulated in treatment works. In Castilla La Mancha, Befesa is currently executing the single wastewater treatment plant for the towns of Bargas, Olias del Rey, Mocejon, Villaseca, Cabañas de la Sagra, and Magan (Toledo), which will serve a population of approximately 100,000.
