"The quality of drinking water will not change, but there will be a change in the efficiency and the amount of reagents used to purify water, which is extremely important in terms of managing and saving resources"
Francisco Javier Fragoso - Mayor of Badajoz. SPAIN.

Water quality deterioration represents a serious environmental, economic and social problem. One of its uses is the production of drinking water for human consumption, which highlights the importance of extracting water of the highest possible quality at the source, in order to minimise the necessary purification treatment, save resources, reduce the environmental impact and possible effects on the health of consumers caused by the use of chemical products and their derivatives.

In order to address these goals, an automatic system was proposed to monitor quality at reservoirs. This provides a real time assessment at different depth levels, so as to establish the best layer from which to draw raw water and thus optimise and save on drinking water treatment.


· Improving the purification process by determining the best depth to draw raw water from reservoirs, based on the quality of the water catchment.
· Positive contribution to consumer health, by reducing the use of chemical products to yield water that is more natural and of higher quality.
· Saving costs and resources by reducing reagents and energy.
· Increasing environmental and socioeconomic security, by reducing waste generation and carbon footprint.
