MADRID, Spain – Spanish companyAqualia has won a €3 million four-year contract to operate the wastewater treatment plant (WWTP) in Burgos, in the region of Castile and León, Spain.
Aqualia will manage a WWTP designed to treat an average daily flow of 156,000 cubic metres per day (m3/day), involving managing the wastewater of more than 1,000,000 equivalent inhabitants.
In its assessment process, the organisation requesting the tenders, Aguas de Burgos, rejected two financial tenders from other participants that it considered “recklessly low”, according to Aqualia.
The new plant ensures the treatment of all the waste of the city of Burgos and its surroundings before discharging into the River Arlanzón.
The WWTP consists of three physical and chemical treatment lines, laminar clarifying, ozonising, filtration and disinfection to re-use the water for services.
The facility also incorporates a thermal hydrolysis process in its sludge treatment before the anaerobic digestion of the sludge and treatment to remove nitrogen in run-offs that optimises the quality of the treated water.
In total, Aqualia manages 48 treatment infrastructures in Castile and León.
