EMASAGRA (Municipal Water Supply and Sanitation Company of Granada, SA) works in the environmental sector, managing all the processes of the integral water cycle: from collection, treatment and distribution, to collection, treatment of used water and return to the natural environment.
EMASAGRA provides its services in 15 municipalities in the metropolitan area of Granada: Alhendín, Armilla, Cájar, Cenes de la Vega, Cúllar Vega, Churriana de la Vega, Gójar, Granada capital, Huétor Vega, La Zubia, Las Gabias, Ogíjares, Otura and Pinos Genil and Pulianas, with a population currently served of 383,030 inhabitants.
Within the project of the II Extension of the EDAR SUR of Granada, all the motor control panels have been renovated and all the existing processes have been automated and added in this phase.
The action has involved the expansion by almost 50 percent of the purification capacity of said station, built in 1990 and which was at the limit of its capacity. In total, the expansion of this treatment plant benefits more than 400,000 inhabitants of the southern area of Granada capital, part of Armilla and La Zubia, Cenes de la Vega, Pinos Genil, Huétor-Vega, and in the future to another 6 municipalities of Cájar, Gójar, Barrio de la Vega de Monachil, Ogíjares, Dúdar and Quéntar.
From the Scada of the control station, 233 electromechanical equipment are supervised and controlled, grouped in motor control centers CCM1 (Pretreatment), CCM2 (Sludge dehydration, CCM2B (Centrifuges), CCM3 (Biological, settling), CCM4 (Cogeneration), CCM5 (Biological Instrumentation), CCM (Digestion), controlled and supervised each of them by several PLCs communicated with each other and with the control center by a fiber optic ring of more than 1 km.
