Spanish state company Aguas de las Cuencas de España (ACUAES), which belongs to the Ministry for Ecological Transition and Demographic Challenge, has invited tenders for a contract valued at €9,220,985 for the operation of water supply services to Zaragoza and the Ebro Corridor as well as the population centres of the Lower Ebro Basin in Aragon.
The contract has a duration of two years, with an option for two one-year extensions, up to a maximum of four years.
The works carried out to improve water supply to Zaragoza and the Ebro Corridor have enabled optimisation of the supply to 850,000 residents of Zaragoza and the surrounding area, through the intake of quality water from the Pyrenees by availing of water surpluses from the Yesa reservoir.
The project was carried out in four stages: the sections from the La Loteta reservoir to Zaragoza, the section from the Sora canal to La Loteta, the Eje del Ebro, Jalón, and Huerva branch lines, and the supply lines to Magallón, Cuarte, Cadrete and Villanueva de Gállego. Total investment in this infrastructure amounted to €163.4 million.
Since going into operation in 2009, the system has supplied 365,998,863 m3 of drinking water, 43,912,965 m3 of which was supplied last year.
The work on the supply infrastructure to the population centres of the Lower Ebro Basin in Aragon required investment of over €21 million. This infrastructure includes an intake structure in the Sástago Canal, two regulation ponds with a capacity of 400,000 m3 and the pipelines required to supply the localities of Villafranca, Nuez De Ebro, Pina De Ebro, Gelsa, Velilla De Ebro, Osera, Alfajarín, Quinto, Alforque, Alborge, Sástago, Cinco Olivas and La Zaida.
A total of 19,997,278 m3 has been supplied to these localities to date, with 1,767,354 m3 corresponding to 2019.
