Aqualogy invests in innovation and the application of state-of-the-art technologies, as well as quality in the execution of its different business areas.


Active management of networks is a basic element in the correct optimisation of infrastructure. To obtain optimum levels in both technical performance and non-revenue water, a network manager (urban supplies, irrigation, associations of municipalities or others) has a number of technology-based management techniques and methods, both for network analysis and restoration work and leak detection/location, which enable high admissible values to be obtained, depending on the conditions of each operation.

This solution incorporates specific control mechanisms and technologies, which permit this ratio to be raised to higher levels in an environmentally friendly and economically profitable way. The combination of the most advanced technologies and applications with the knowledge, experience and analysis methodologies in each network, make this possible.


Activities throughout the drainage and sewerage field, from the design of systems to their active operation. These solutions consist of high added-value services, including: discharge control systems, real-time management, sewerage network cleaning and master plans. The environmental approach, an important technological contribution and extensive resources and geographical coverage constitute a guarantee for the proposed solutions.


Wide offering covering the whole range of possible needs in the field of irrigation. The Aqualogy offering touches upon all aspects, including important areas of company knowledge and know-how. We can intervene in any of the implementation phases of an irrigation system (engineering, construction, system engineering, management, technology implementation, etc.), presenting complete or specific proposals, depending on the customer's needs.
