Extension of the wastewater treatment plant in Burgos
In order to improve the treatment of all of the wastewater produced by the city of Burgos and the surrounding area, the city’s wastewater treatment plant is being extended.
The aim of the project is produce effluents of a sufficiently high quality that they can be discharged with minimal impact on their final receiving environment, the Arlanzón river. Once the extension is complete, the wastewater treatment plant will have the capacity to treat 150 000 cubic metres of water a day, providing a huge benefit to the estimated 180 000 inhabitants of Burgos and the surrounding villages.
Improving treatment, measure by measure
From a technical perspective, the project is broken down into several measures.
A new water treatment line in the new plant will be created to receive wastewater through two pipelines from a capture system in the main sewer. This water treatment line will comprise: pre-treatment, primary sedimentation, bioreactor, secondary sedimentation and discharge of effluent.
Additionally, a new sludge treatment line will be created and the water treatment line in the existing plant will be refitted. Meanwhile, the current biological treatment facility will be refurbished and will go from one to two lines, with a 20% anoxic area in order to eliminate some of the nitrogen.
The refitted sludge treatment line to be shared by the new and existing wastewater treatment plants and, after dewatering, the sludge from both plants will be treated together. A new dewatering facility will be built next to the thermal drying facility.
The effluent will then undergo tertiary treatment so that only disinfected water can be discharged into the river.
The average volume to be treated in the enlarged facility will be approximately 150 000 cubic metres of water per day, which is approximately an increase of 50% on the existing facility.
Benefits for the inhabitants and environment of Burgos
The project, which is scheduled to be complete by December 2013, will have a significant impact on the environment of Burgos and improve the city’s environmental sustainability by improving the quality of effluent so that it can be discharged into the Arlanzón river with minimal impact.
Meanwhile, the estimated 180 000 connected to the sewerage system will benefit from a 50% increase in the plant’s treatment capacity. Finally, the project is expected to directly create 36 jobs during the implementation stage and 13 during the operational stage thus benefitting the local economy.
