Aguas de Burgos − a company owned by Burgos City Council that directly manages services related to the end-to-end water cycle – has awarded ACCIONA the maintenance, conservation and operation of the wastewater treatment plant (WWTP) at Villalonquéjar. It treats the wastewater from the locality’s industrial estate and the city of Burgos and the surrounding area.

The contract –valued at €18.2 million− will run for four years, plus a one-year extension.

The company will work on the water treatment, sludge, gas and cogeneration lines with the aim of guaranteeing a quality water service to the city and optimising the energy consumption of the plant.
