AQUALIA It is one of the leading companies in comprehensive water cycle management in Spain and Europe, with an international presence. Its operations encompass water collection, treatment, distribution, sanitation, and wastewater treatment, serving millions of citizens and public administrations.
AQUALIA operates according to principles of operational efficiency, environmental sustainability, and public health safeguards, and is a key player in the responsible management of water resources in municipalities such as Aldea del Fresno (Madrid), where it has taken action to resolve a serious water quality problem and ensure the future management of the drinking water supply.
Location: Aldea del Fresno (Madrid)
The Aldea del Fresno City Council, through AQUALIA, was facing a serious water quality problem due to the high concentration of dissolved manganese in the groundwater, with values ranging from 500 and 1,000 ppb, well above the legal limit of 50 ppb established by the Royal Decree 03/2023 for water intended for human consumption.
This situation led to months of repeated interruptions in the drinking water supply, with a significant social impact on the population and an ongoing dependence on tank trucks, which entailed high economic costs, a significant increase in the carbon footprint associated with water transportation, and a solution that was clearly unsustainable in the medium and long term.
The challenge was to restore the continuous supply of drinking water, in compliance with health regulations, in a reliable, efficient, and environmentally responsible manner.
From AZUD, and in close collaboration with AQUALIA, the design data provided by the client was analyzed to determine the best technical and economic solution, optimizing the available space and minimizing the consumption of water, energy, and reagents.
The solution implemented was a containerized water treatment plant AZUD, consisting of two 40-foot high-cube containers, designed to treat a flow rate of up to 180 m³/h and specifically designed for the manganese removal.
Each container includes:
The entire complex was designed based on a single concept Plug & Play, thereby reducing civil engineering work and implementation timelines.
Thanks to the solution that was implemented:

AZUD conducted a comprehensive analysis of the project context, taking into account pump curves, head losses, distances, elevations, existing materials, operational limitations, and actual operational needs.
The plant was designed, manufactured, commissioned, and validated by the AZUD engineering team, with follow-up visits and technical support to ensure proper long-term operation.
