The agreement will see the construction of the new Tamarguillo Drinking Water Pumping Station (DWPS) and the upgrading of different sections of the Puerto outfall sewer, with maximum expenditure of 93.5 million euro. The agreement between the Guadalquivir River Basin Management Authority and the Empresa Metropolitana de Abastecimiento y Saneamiento de Aguas de Sevilla, S.A. (EMASESA) is part of ongoing actions to upgrade treatment at Seville WWTPs in the sensitive area around Doñana.

The Spanish Cabinet, on the proposal of the Ministry for Ecological Transition and Demographic Challenge, has authorised the Guadalquivir River Basin Management Authority to enter into an agreement with Empresa Metropolitana de Abastecimiento y Saneamiento de Aguas de Sevilla, S.A.
