Reclaimed water in Spain has a new regulatory framework. The RD 1085/2024 aims to guarantee the safety of reclaimed water for various uses and to promote water sustainability. In this way, Spain is aligned with the European standards of quality, control and European sustainability requirements on water reuse contained in the European Regulation 2020/741, and promotes the adaptation of the European Green Pact.In Adasa we lead the use of digital solutions that will help to guarantee the quality of reclaimed water, detect bacteriological contamination and facilitate compliance with this new royal decree.
The ultimate goal of the approval of RD 1085/2024 is to reduce pressure on water resources, promote the circular economy and help mitigate climate change. The main novelties of the new regulation are:
Water quality criteria according to useThe regulation distinguishes five large groups of reclaimed water quality classes according to the concentration of a bacteriological contamination indicator such as E. coli (Escherichia Coli): A+, A, B, C and D and considers that there is an absence of E. coli when its concentration is less than 1 CFU /100 mL.
In all uses of reclaimed water and environmental destinations, and in all quality classes, the frequency of control must comply with the continuous measurement of flow and turbidity.
In addition, it must be taken into account that the different AMVs established in RD 1085/2024 imply that the associated indicative treatment varies according to each quality class:
Microbiological and physicochemical controls are required for each of these use cases, a field of application in which Adasa has extensive experience and knowledge, as well as in the detection of bacteriological contamination.
Validation of SCBAThe new regulation also establishes that Water Regeneration Station (WRS) validation is performed quantitatively to determine indicators of 3 types of pathogens: bacteria (E. coli is the indicator microorganism, whose treatment chain performance target is set at ≥ 5.0), viruses and protozoa.
Compliance with the performance target may be established by analytical control on the basis of scientific evidence for consolidated standardized processes such as published data from test reports or case studies; or tested in a laboratory under controlled conditions for innovative treatments.
Adasa and the quality of reclaimed waterAdasa offers solutions for the identification of bacteriological contamination such as aquaBio, which allows compliance with the requirements of RD 1085/2024 on the reuse of reclaimed water through continuous monitoring and real-time microbiological analysis of water quality indicators and microbiological contamination such as E. coli, enterococci and total coliforms. This system ensures the systematic measurement of E. coli and has the ETV (Environmental Technology Verification) that accredits the reliability of the results compared to the ISO 9308-2 method.
Adasa provides diverse and integrated solutions that combine proprietary and third-party technologies. However, one of our fundamental differentiators is our in-depth knowledge of water quality, highlighting both our experience in the development of sensors and their optimal integration in different contexts and applications. This approach positions us as a benchmark in ensuring the safe use and quality of reclaimed water and in the analysis of bacteriological contamination.
