Urban Cycle

Government agencies and public companies, whether municipal, supramunicipal or regional, are, in most countries, the bodies with jurisdiction over activities related to the urban water cycle: supply, sewerage networks, the subsequent wastewater treatment processes and the water’s return to the environment.

Aqualogy, a leading brand in integrated water solutions thanks to the experience it has garnered in managing over 2,000 water facilities worldwide, has the technology and integrated solutions necessary to meet any and all challenges associated with complete water cycle management in the urban environment.

Our value proposition, focussed on improving efficiency and guaranteeing quality, follows a model of customer collaboration and consists of the following solutions:

  • Management of wastewater, desalination and drinking water treatment plants.
  • Efficiency in water networks.
  • Drainage and sewerage network.
  • Design, construction and rehabilitation of water infrastructure.
  • Water company revenue management.
  • Water quality and bio-safety: environmental services and analytical services.
  • Supply of hydraulic materials and water treatment products.
San Sebastián commits to Aqualogy’s advanced sewerage network management system

Innovation, occupational health and safety and advanced technology are some of the aspects that enhance the values of the service Aqualogy is providing in San Sebastián, where it has been responsible for the maintenance and cleaning of the city’s sewerage network since 1 June 2013.

Aqualogy contributes ‘intelligence and technology’ to the maintenance of San Sebastián’s sewerage network, which covers some 786 kilometres and includes 31,600 shafts and manholes and 28,000 drains.

The Galia method, which features innovative and advanced sewerage cleaning management, is a tool that offers high performance, respect for the environment and continuous water recycling.

Aqualogy manages and maintains Zaragoza's sewerage network

Aqualogy manages and maintains Zaragoza's sewerage network

Aqualogy is responsible for the management of Zaragoza’s sewerage network cleaning, maintenance and inspection services. It centres on the technological improvement of the service through the implementation of advanced cleaning management tools such as Galia, WiCast and GISAgua, as well as improving the cleaning and inspection equipment, with a sustainable and technologically advanced approach.

The network covers some 1,134 kilometres and serves a population of 650,000 inhabitants. In addition to network cleaning, maintenance and inspection tasks, Aqualogy is responsible for updating and maintaining GISAgua.

The project also covers the calibration and application of a mathematic model, a technology that proposes improvements and anticipates the behaviour of the network.

Ecociudad Zaragoza, a sewerage and wastewater treatment company wholly owned by the city, has entrusted the management of this service to Aqualogy, Socamex and Ideser for a period of two years.

With this action, Aqualogy is now the leader in the maintenance and operation of sewerage networks in Spain, serving some 9.3 million people.

Aqualogy manages local company SALEAL’s WWTP

Aqualogy manages local company SALEAL’s WWTP

The WWTP treats the wastewater of the association of municipalities of León and its metropolitan area (SALEAL - Mancomunidad Municipal para el Saneamiento Integral de León y su Alfoz), which is formed by León, San Andrés del Rabanedo, Villaquilambre and part of Santovenia de la Valdoncina.

This facility serves 185,000 people in the city of León and its metropolitan area. It also treats the wastewater of León’s industrial estate. In total, the water treated is equivalent to that of a population of some 350,000 inhabitants.

The facility includes a cogeneration system with two engines that use natural gas to produce electrical energy. The exhaust gases from these engines, which are in part powered by biogas from the wastewater digesters, are used to thermally dry the sludge (achieving dryness levels of up to 95%) and maintain the digesters at a constant temperature of 35°C.

Aqualogy started to manage the WWTP in 2011 for a period of 25 years.


Aqualogy’s plant operation activities are undertaken with the aim of optimising the different processes by applying the latest technologies, minimising energy consumption, ensuring treatment performance levels and carrying out analytical controls of water quality, in addition to ensuring correct environmental management of sludge, waste, brine and by-products generated in the treatment processes.

The requirements for the energy or agricultural recovery of sludge mean that end users demand an easily manageable, storable and innocuous product. Accordingly, it is necessary to perform more comprehensive sludge treatments. These treatments are carried out in units and with complex industrial processes, the management of which requires a high degree of specialisation. Aqualogy has become a specialist in the operation and maintenance of these treatment platforms.


  • Hydraulic engineering. Consultancy in hydraulic engineering.
  • Energy efficiency. Integrated service for all energy-related matters: energy audits, comprehensive energy management, energy efficiency projects, and the design, project development and construction of renewable energy installations.
  • Control systems. The Aqualogy solution covers all phases and needs of the project from consultancy and advice to after-sales service, covering supply, installation and commissioning.
  • Dynamic micro-sectorisation. Reduction in the duration of all leaks by early detection through constant, localised monitoring of the entire network.
  • Hydrogeology and groundwater catchment. Full range of activities related to aquifers and groundwater.


To achieve optimal levels both in the technical performance of the network and in non-revenue water (NRW), it is necessary to implement technologies in network analysis, rehabilitation work and leak detection and additional control mechanisms. Implementation projects must be carried out sequentially with a clear methodology to achieve the desired results. The required actions vary, depending on the interim results obtained during the different phases. Information analyses and technical proposals are supported by field experience and historical information and, in advanced phases, the installation of specific equipment is also required. Aqualogy is the ideal partner for undertaking a project of these characteristics, thanks to both its capability and experience.


In this area Aqualogy has developed a methodological and technological proposal called Galia (advanced sewerage network cleaning and maintenance). The key lies in having maximum knowledge of the status of the network in order to determine its actual needs. Our Galia methodology allows us to determine where, when and how often cleaning is necessary. We prefer to act where necessary and increase frequency at the hot spots where action is required. In addition, Galia makes it easier to decide on the most appropriate resources for each requirement, thus obtaining results of the highest quality and a functional guarantee.


Aqualogy has proven and recognised experience in the design and construction of water infrastructure:

  • Wastewater treatment plants (WWTP)
  • Drinking water treatment plants (DWTP)
  • Seawater treatment plants (SWTP)
  • Drinking water supply networks
  • Wastewater sewerage networks
  • Channelling and riverbank defences

Aqualogy offers integrated solutions for a complete facility cycle, and may subsequently participate in its operation, with the guarantee this represents.
