Monitoring water parameters is key to understanding the evolution of an installation's conditions and quickly detecting any anomalies. In buildings with complex networks, having continuously recorded data facilitates tracking, aids in interpreting changes, and provides valuable information for maintenance.
Regulations, such as Royal Decree 487/2022 and its amendment by Royal Decree 614/2024, mandate the control of various physical-chemical parameters, allowing for some to be monitored using continuous automatic reading systems. The value of these systems lies in the ability to analyze a series of data alongside other installation controls.
Parameters like pH, temperature, and turbidity can be continuously monitored. Temperature, for instance, helps track operational conditions, particularly in domestic hot water systems. pH is crucial when its effectiveness depends on the disinfectant, and turbidity provides an additional reference for water quality. Conductivity is also included in the controls for certain installations.
The selection of parameters to measure should align with the specific characteristics of the installation, the applied treatment, and the control program's objectives, rather than a generic list. Continuous monitoring provides frequent records that can reveal changes missed between spot measurements, offering a broader context for analyzing potential issues or trends.
To ensure data reliability, measurement equipment requires periodic maintenance and calibration, adhering to regulatory requirements for analysis methods and measurement uncertainty. Continuous records are only useful if measurements are reliable and properly interpreted.
Continuous monitoring does not replace established controls. Automatic measurements and laboratory analyses offer complementary information. Integrating these records into the existing control system, considering the location of measurement points in complex networks, is essential for effective water management.
In highly complex buildings, such as hospitals, or installations with water networks requiring specific monitoring, defining control points and selecting sensors must address concrete needs. Monitoring should be integrated into maintenance and treatment programs, aiding in decisions about equipment revisions or process adjustments.
An effective monitoring system requires defining parameters, frequency, measurement points, and action procedures for deviations beforehand. It should not be confused with automatic diagnostics; data interpretation, especially for preventing Legionella or other microorganisms, must complement maintenance, treatment, and cleaning measures.
The utility of continuous monitoring depends on the accurate definition of measurement points, equipment reliability, and the integration of information into control and maintenance procedures. To assess which parameters to monitor or how to integrate records into installation control, Alcora offers personalized studies of the system and specific needs.
