Sando Agua is the Sando company dedicated to the design, construction, maintenance, conservation and operation of infrastructures related to all phases of the water cycle. Committed to the environment, it leads projects to optimise the management of this vital resource, providing quality, experience and continuous innovation.

The company develops solutions for each of the phases of the integral water cycle: collection, treatment, distribution, sanitation and purification, decarbonisation, waste management and recovery. These solutions include actions such as the construction of drinking water treatment infrastructures, distribution and sanitation networks, treatment plants (EDAR), drinking water treatment plants (ETAP), or desalination plants (EDAM).

As a Sando company, a commitment to innovation is in its DNA. It manifests in adopting the technological perspective as the cornerstone of its operations. To this end, Sando Agua integrates the SmartWater Cycle into its water infrastructure management, an innovative approach to water management. This cycle integrates advanced information and communication technologies (ICT) to collect real-time data and optimise water management.

Through this technological application, the company implements IoT (Internet of Things) devices or uses sensors to collect data on water quality and quantity in real-time at each stage of the water cycle to minimise water loss in the distribution or prevent contamination.

In addition, aware that efficient and sustainable water management involves investing in R&D&I, it is launching research projects to study alternative solutions for improving the quality and safety of actions or in the circular economy and energy recovery.

One of these research projects is ENBIO, which seeks to evaluate the capacity of biogas obtained in the anaerobic digestion of sewage sludge from a wastewater treatment plant (WWTP) to generate biomethane.

Subsequently, its potential as a source of renewable hydrogen production can be developed through oxidation with renewable oxygen obtained through electrolysis.
