Aqualia has been awarded the contract to operate the Burgos WWTP. The specifications required the delivery of a very advanced and innovative technical offer, in line with a sustainable and coherent economic proposal, and this was precisely Aqualia's great asset. The tendering entity, Aguas de Burgos, in its evaluation process has dismissed two economic offers for being considered "reckless casualties".
Thus, the company will manage an EDAR designed to treat an average daily flow of 156,000 cubic meters, which involves managing the wastewater of more than 1,000,000 equivalent inhabitants. The new plant ensures the purification of all the discharges of the city of Burgos and its alfoz, producing effluents with a sufficient quality for its later reutilization and with a minimum incidence in the Arlanzón river, to which the purifier pours. The contract lasts for four years, renewable for another two, and an overall portfolio (value) of almost thirteen million euros.
The WWTP has new purification technologies such as the treatment of excess flow in rainy season, which can also be operated in dry weather as a tertiary treatment, which consists of three lines of physical-chemical treatment, lamellar decantation, ozonization, filtration and disinfection for reuse as service water.
In addition, a process of thermal sludge hydrolysis prior to the anaerobic digestion of the sludge is incorporated into the sludge treatment, and a nitrogen removal treatment in the drains that will allow the optimization of the treated water quality.
Aqualia manages 48 purification infrastructures in Castilla y León, which makes it, by treatment capacity, the undisputed leader in this Autonomous Community.
