Excellence is one of our goals, therefore we work tirelessly to improve and respond to the demands of the environment. We continuously strive for innovation, safety and ever more efficient technology. We also offer our customers a team of highly qualified professionals to resolve their most frequent doubts.


Environmental conservation and respect are present in all business decisions. Firmly following our company policy, which focuses on preserving the environment, it has been deemed right to comprehensively certify our processes.


The main meaningful environmental aspect in 2017 was the generation of sludge from the WWTPs under our management. A volume of 17,770t was reached, which meant an increase of 20% on the previous year. This was fundamentally due to the incorporation of new facilities and the expansion of the existing sanitation network.


The evolution of sludge generation in recent years has been as follows:


2016 > 14.727,36 t


2017 > 17.770,13 t


2018 > 17.017,68 t


The total amount of sludge produced in the past year, 2018, was 17,017.68 t. The figure is similar to the result of the previous year, owing to the unchanged number of operating facilities. However, a relevant fact is that there is an average increase of 2% in dry matter over the total fresh sludge generated, which has resulted in a decrease in residue (water present in the sludge) of approximately 50 t. This reduction has meant, in addition to a logical saving in the costs of sludge transportation and management, a decrease in the volume of generated waste.


This has been possible thanks to a number of factors:


1º.- WWTP personnel who are in charge of the tasks of drying and dehydrating the sludge enjoying greater involvement and the streamlining of the equipment for the treatment of sludge in the plant.


2º.- Laboratory level tests followed up by on-site tests on the new ranges of state-of-the-art coagulants, mainly of “reticulated” polymers, in the WWTP.


3º.- Monitoring of the measures taken and analysis of the results obtained by the plant’s Operation Technician.


100% of the sludge generated in 2018 has been appraised, and its journey’s end was as follows: compost (68.5%), elaboration of artificial soils (30%) and agricultural fertilizers (1.5%).


Our occupational health and safety philosophy is based on raising staff awareness; on the fact that work safety is also the responsibility of each person. We make it clear that everyone is equally responsible for safety and for the people who depend on us. This culture, aimed at the effective implementation of all the established health and safety measures, has led to very low rates of work-related accidents.


Collaboration with the contractors working within our plants is one of the cornerstones upon which our companies’ health and safety policy sits. The group is effecting an ambitious audit and training plan for contractors, aimed at guaranteeing the quality standards established by the company. The focus is directly aimed at minimising risks at our work centres.


Water Cycle


Complete water cycle, is the expression that defines the whole life of water, from its catchment in nature as a raw material to its availability in our homes as drinking water, and back to nature after treatment.


From its catchment in springs, wells, reservoirs, etc., and after going through the treatment stations that purify it, where it is object of stringent controls, water is transported to storage tanks built in towns and then, through the distribution systems, arrives to the user.


Once used, it is channeled through the sewerage network to the wastewater treatment plant, from where it returns to the natural environment with all guarantees.
