2015 IN ACTION

Below we describe some of the actions that SUEZ Water Spain companies have undertaken in this area: Aguas de Murcia uses systems for managing water, such as micro-sectoring, which allows real-time monitoring of the state of the network and immediate detection of leaks. Its use of innovative systems in water management meant it was selected by the Ministry of Industry, Energy and Tourism as an example of the development of smart cities. Sorea applied Aqua Freed® technology in 2015 to restore several wells in the provinces of Barcelona and Girona, with highly satisfactory results in terms of flow improvement, providing savings through lower energy costs and water purchasing, as well as improved supply guarantees, lowering the risk of availability problems in the summer. Sorea carried out a reuse action for the Vila-seca wells for irrigation in the municipal area. HIDRAQUA also reuses treated water to restore the Recorral leisure area, helping reduce water consumption. As part of the Water Efficiency Plan, in 2015 Aguas Andinas carried out a series of pilot tests on 170 km of network in order to fine-tune methods and technologies for reducing network water loss. SUEZ Water Spain presented the functions and benefits of its AQUADAPT software, a new solution to optimise operating costs in large supply networks. AQUADAPT improves operations planning for water treatment plants, pumps and valves, thus providing energy savings. The first implementation of the software in Spain took place in the facilities of the Consorci d’Aigües de Tarragona. It is estimated that during its first year in operation it generated between 8% and 10% savings. Aigües de Barcelona improved the efficiency of the supply network and demand management, thus further guaranteeing the water supply in the Barcelona metropolitan area. Since the last drought in 2007-2008, accumulated savings are 42.5 hm3. SUEZ Water Spain implemented an energy use and micro-hydraulic potential calculation project for Emasesa, Empresa Metropolitana de Abastecimiento y Saneamiento de Aguas de Sevilla, S.A. The project includes a specialist technical consultation study on energy efficiency, to analyse the general network operating conditions and thus determine available micro-hydraulic potential. One of the main conclusions is that the pressure

available in the networks could be used to produce energy. In this context, SUEZ Water Spain , under the brand name Sistemas de Generación Hidráulica (SGH), has developed products specially designed to provide optimum energy recovery in sites with hydroelectric potential. Astosam, in conjunction with Cetaqua Andalucía, the Andalusian Water Technology Research Centre, and the University of Malaga, initiated the SEGVERT research project for detecting possible discharges into the sea, with the aim of guaranteeing bathing water quality along the Torremolinos coast. The smartphone app iBeach, developed by SUEZ Water Spain, was chosen by SUEZ as the app for the Marseille beaches, under the title ‘Marseille InfosPlages’. Using the iBeach structure, this new app offers information on the state of the beaches, with a description, photos and a sea and weather forecast for this French location. Through this strategy, the company enables all towns to have their own beach app at a very competitive price. SUEZ Water Spain developed the iBeach app for Aguas de Alicante. As part of the Cetaqua DESSIN project, Aigües de Barcelona injected sand-filtered water (pre-drinking water) into the Sant Joan Despí WWTP well. Refilling the aquifer with sand-filtered water will reduce costs compared to the previous system (Sant Joan Despí WWTP drinking water), thus improving joint management of surface and ground resources. Aigües de Barcelona developed a reclaimed water supply management model in the Barcelona metropolitan area to promote the circular economy, introducing the use of reclaimed WWTP water as a means of using water resources. In 2015, this action involved executing a reclaimed water supply to a company in Zona Franca in Barcelona. EMASAGRA and AGUASVIRA worked to identify sewerage connections in canals through internal inspections with CCTV in the towns it manages, with the aim of drawing up a technical-financial action plan to eliminate wastewater and rainwater connections in the canals.
