ACCIONA Agua’s activity is focused on safely and efficiently delivering all aspects of the water cycle to people. ACCIONA Agua is an industry front-runner in water treatment providing the design, construction and operation of drinking water, desalination, municipal wastewater, industrial wastewater and tertiary treatment plants, including those for water reuse.
ACCIONA Agua also offers end-to-end service management covering each step of the water treatment process, making water fit for human consumption, delivering it to the consumers, treating urban and industrial wastewater, and billing end-users.
The Research Development and Innovation (RD&I) Department’s support in all phases of the water cycle sets ACCIONA Agua apart from others. In desalination, the ACCIONA Agua works with the state-of-the-art membrane models and new energy recovery devices and is continuously researching new water treatment techniques. The RD&I team provides technical support and are world leaders in the concept design of large-scale desalination plants.
ACCIONA Agua cooperates with universities and public research centres in national and international research projects, positioning the company at the forefront of technology and attach it as a leader in the sector. ACCIONA Agua has developed various RD&I projects which have been selected by the European Commission to form part of the LIFE+ programme, such as OFREA, aimed at improving the quality of treated water to foster reuse in coastal areas, implemented together with ESAMUR.
ACCIONA Agua is also partnering with this agency on the RENEWAT project. This project aims to adapt several sources of renewable energy such as solar panels and small wind farms to a wastewater treatment plant and integrate them with a smart management system to coordinate water treatment processes with available energy. Another LIFE+ project coordinated by the RD&I centre is BRAINYMEM, which focuses on reducing the energy dependence of the wastewater treatment plants by 20% to 50% through advanced biological process control systems. The research carried out has resulted in more than 19 patents related to desalination technologies, membrane bioreactors and reuse, including:
ACCIONA Agua has a highly qualified team with more than 30 years’ experience in applying RD&I to water treatment and the use of membranes, from the most basic laboratory techniques to industrial-scale studies in pilot plants.
In 2014, the RD&I Department identified 51 innovative projects with a turnover of more than €18M.
Drinking-water treatment or purification process consists of a series of actions to treat the water in order to make it “potable”, suitable for human consumption.
ACCIONA Agua offers a range of innovative solutions designed to overcome the problems associated in the treatment of water to provide safe drinking water. ACCIONA Agua has built over 100 drinking water plants l, with a total capacity of more than 7million m3/d, enough to satisfy the water needs of nearly 26 million people.
Wastewater or Sewage treatment consists of a series of processes that remove or reduce the physical, chemical and biological contaminants from water coming from the public or industry to achieve the quality and required effluent characteristics.
ACCIONA Agua delivers efficient wastewater treatment solutions at minimum “whole of life” costs. The company operates and maintains more than 300 wastewater treatment plants with a total capacity of 13.2 million m3/d, which meets the needs of a population equivalent of nearly 54 million.
Desalination consists of a series of processes to remove part or all salt and other minerals from brackish water or seawater to transform it into suitable for irrigation or drinking purposes. The desalination process is known as Seawater Reverse Osmosis (SWRO).
ACCIONA Agua is a leader in Reverse Osmosis, for both sea and brackish-water desalination. The Company has a very broad experience covering the entire project life-cycle: design, build, commission, and O&M.
ACCIONA has built more than 70 desalination plants, producing a total of over 2.3 million m3/d, supplying potable water to more than 10.5 million people.
ACCIONA Agua runs WTPs and WWTPs with its sights set on optimising all aspects of the treatment processes by applying cutting-edge technology, minimising energy consumption, carrying out ongoing tests to monitor water quality, and efficiently managing the sludge, waste and by-products generated by the treatment processes.
ACCIONA Agua applies a policy of sustainability in the operation and maintenance of its facilities, for example by minimising emissions of odours and noise, reducing energy consumption, whenever possible using renewable energy and reusing effluent water in the preparation processes for reagents.
The original G&AWS scheme was developed in 1895 when C. Y. O'Connor engineered a scheme to deliver 23 MLD of untreated water to the Goldfields region through the construction of the Mundaring Weir, 530 kilometres of 30” pipeline, and delivered using eight steam-driven pumping stations. A world class engineering feat of the era! Since then this water system has been progressively upgraded, the new Mundaring Water Treatment Plant and pumping stations being the latest of these improvements to be implemented.
The desalination plant is a key part of the South Australian government’s Water Proofing Adelaide Strategy. It can provide Adelaide with half of its annual water usage and is powered by sustainable energy sources.
