We are committed to the change in the management and maintenance of urban wastewater treatment plants

Traditionally, the objective of wastewater treatment was to protect the health of users of the channel who were downstream of the discharge point. Over the past few decades, the additional objective of protecting surface waters from nutrient pollution has been added, bringing Wastewater Treatment Plants (WWTPs) to technologies for the removal of nitrogen and phosphorus from wastewater.



Despite the growing need to consider wastewater as a resource, most public water management services continue to focus more on the collection and treatment of wastewater than on the recovery of the resources it contains. To implement resource recovery processes in WWTPs, water management utilities must extend their engineering expertise towards resource recovery.  In Laboratorios Tecnológicos de Levante S.L. (LTL) we have a long experience in the control of the operation and maintenance of WWTPs, which can allow you to assist public agents in this work of reengineering urban treatment plants.



It must be guaranteed that the wastewater that is received maintains its urban character, since the processes of resource recovery that are implemented will have as a starting base that quality of the water received, and this will be critical in its performance. Here LTL is alsoable to provide valuable help to the managing bodies of these new facilities, since we have been collaborating with different administrations for many years in the inspection and characterization of industrial discharges to protect the operation of urban WWTPs.



The most precious resource contained in urban wastewater is water itself. Wastewater reuse can provide an alternative source of water particularly in our region, where we can expect an intensification of periods of drought due to climate change. It is possible that in the future the legislation that regulates the quality of water for its different uses will be much stricter, requiring the elimination of emerging contaminants. In 2019 LTLconcluded, together with other collaborators, the LIFE-EMPORE project, in which different combinations of new technologies were tested in order to find the optimal processes for the elimination of emerging contaminants.


Finally, it should be noted that in LTLwe have a wide scope of accreditation that covers not only the analysis of water, but also that of sludge and other waste generated in WWTPs, being particularly important the microbiological analysis of sludge, whether fresh or composted, which allows to check if they have been properly sanitized before use.


Are public water management services prepared to conceive of urban wastewater as a valuable resource rather than a waste? We still have to overcome technical, economic and environmental problems in order to take advantage of the potential of resources that wastewater has that could make us a more sustainable society.
