design, engineering and construction

Aqualogy, the global brand providing integrated water and environmental solutions and technologies for sustainable development, is a benchmark in the design, engineering and construction of water infrastructure.

Services offered include design engineering, technical advice, civil works, equipment supply, electromechanical assembly and commissioning of facilities. We have experience in building all kinds of water and environmental infrastructures:

  • Industrial effluent and wastewater treatment plants
  • Desalination plants (seawater and brackish water)
  • Arsenic treatment plants
  • Water reuse and supply networks
  • Industrial effluent and wastewater treatment and sewerage networks
  • Sulphate treatment and metal recovery
  • Irrigation modernisation

Aqualogy offers supplementary solutions for infrastructures with the aim of providing a comprehensive approach to the field of water and reuse of water resources, as well as participating in their operation:

  • Design and engineering
  • Construction
  • Start-up and operating tests
  • Operation and maintenance
  • Accredited specialists in improving the efficiency of facilities


Aqualogy’s experience in building wastewater treatment plants is backed by 506 facilities operating worldwide, with a treatment capacity of over 4,222,153 m3/day.

Some of the notable facilities in recent years include the Mapocho blackwater treatment plant in Santiago de Chile, with a treatment capacity of 570,000 m3/day, the Torrevieja blackwater treatment plant, designed to treat 60,000 m3/day, and the Arroyo de la Miel blackwater treatment plant in Malaga, with a capacity of 40,000 m3/day.


Drinking water treatment plants (DWTP) designed and built by Aqualogy use both conventional flocculation–filtration–chlorination treatments and state-of-the-art drinking water production technologies (membranes, microfiltration, disinfection using CO2, etc.).

Our proven experience in building DWTPs can be seen in the 250 drinking water treatment facilities in operation all over the world, with a total treatment capacity of 6,020,657 m3/day.
Our most recent and significant works include those for the project to improve the reverse osmosis water treatment at the Sant Joan Despí DWTP in Barcelona, with a capacity of 206,000 m3/day.


Although Aqualogy’s main business in the field of infrastructure is the design and construction of all kinds of water treatment facilities, we have a team of technicians who specialise in executing water infrastructures in general:

  • Drinking water supply networks: catchment, pumping stations, pressure pipes, reservoirs and water tanks, distribution networks and network renovations
  • Wastewater treatment and sewerage networks: pressure pipes, collector sewers, outfalls, storm tanks, etc.
  • Channelling and riverbank defences


Aqualogy offers a solution for the production of high-quality water, regardless of the source of the water to be treated (sea or brackish water from aquifers).

Notable among our 17 desalination plants in operation is the seawater treatment plant for the Barcelona metropolitan area, with a drinking water production capacity of over 200,000 m3/day.


Arsenic (As) is a chemical element present in the environment and highly toxic in its inorganic form.
According to the World Health Organisation (WHO), prolonged consumption of water rich in arsenic represents a significant threat to public health.

In dealing with this problem, Aqualogy and AdEdge Technologies provide institutions, water companies and industrial processes with specific, clean and profitable solutions that guarantee the removal of arsenic from water and compliance with local regulations.

Aqualogy’s offer integrates the design, development, manufacture and supply of innovative technologies. The AdEdge equipment is an unbeatable offer, with technically proven technologies and a significant Spanish and international presence. To date, over 400 removal projects have been implemented worldwide.
