Formentera Water Smart island Daisee Aguilera, Councillor for the Environment – Formentera Island Council Ángel Encinas, Project Manager, Innovation Dept. – Aqualia Formentera needs your green side Background • Increasing population every year ➢ Since 2005 the # passengers has doubled to 1,800,000 in 2017 • More than 4 times the population in the summer season

ANNUAL POPULATION (2002-2017)

Balearic Islands FORMENTERA

• No water policy • Exploitation of aquifers to the limit • Limited production of drinking water which only comes from desalination plants • It’s not a custom to drinking tap water • The island suffers a severe drought due to the lack of rain

Critical situation of water resources Alliance for Sustainable Water Management

• Made up of representatives from public institutions, private entities, social and agricultural sectors • Overall goal: An integrated freshwater islands management

Source: http://www.alianzaaguaibizaformentera.org/en/) Awareness-raising campaign

• Alliance members jointly support and promote awareness campaigns, information and training workshops designed for specific audiences with tailored messages • In 2015 Aqualia launched a Communication Plan in Ibiza and Formentera with the aim of promoting a responsible use of freshwater. This plan was based on a proactive strategy actively involving citizens, administrations, and the private sector making be a part of a unique goal • Since 2016 the Alliance has led the campaign “Enjoy the island, Save water”, which has a positive message aiming to raise awareness about the value of water supply among the final user: residents and tourists Remote smart metering system: the case study of Sant Ferran (Formentera) Sant Ferran (Formentera) • 230 domestic water metres with remote reading • 8 municipal metres • 1 district water metre supplying water to town

This remote reading system allows a smart control of the water consumption through the domestic metres of each user and the water provided to the distribution network Remote smart metering system: the case study of Sant Ferran (Formentera) Water metres Radio Aquacity network coverage FORMENTERA

Sant Ferran

Sant Ferran (Formentera) Remote smart metering system: the case study of Sant Ferran (Formentera) Basic overall operation

This remote reading system enables the combination of several means of communication and the implementation of different protocols in the reception of data, becoming a universal system: - Multi protocol - Multi frequency - Multi manufacturer Remote smart metering system: the case study of Sant Ferran (Formentera) The remote reading system is a versatile and advanced system that enables to read metres from various manufacturers

Water meter manufacturers

The software is available for the local government for better water management Remote smart metering system: the case study of Sant Ferran (Formentera) • Manual readings in the 2,301 water metres in Formentera island in 2016: 9,204 • Remote readings in the 238 water metres in Sant Ferran in 2017: 2,084,880 Advantages: • No need to access residential buildings or individual homes for metre readings • No need to estimate readings when access is not possible • Fast water leakage detection inside residential homes → No high bills to end consumer Remote smart metering system: the case study of Sant Ferran (Formentera) Functions ➢ Alarm activates in case of: • Excess flow (undersized metre – operating at maximum range) • Water return • Metre tampering (water fraud) • Stopped metre • Leakage ➢ Synchronized reading every hour: • Real time reading minimizing unregistered water Remote smart metering system: the case study of Sant Ferran (Formentera) Continuous water leakage detection (end user): Remote smart metering system: the case study of Sant Ferran (Formentera) Continuous hydraulic balances (Sant Ferran network):

Hourly control of unregistered water in the network: Leakage + Fraud + Uncontrolled consumption (irrigation, street cleaning)

UNREGISTERED WATER ASSESSMENT ANOMALY DETECTION IN THE NETWORK By determining the user consumption profile, Early detection of anomalies enables preventive it is possible to act on the different variables actions avoiding unnecessary water loss of the network, minimizing water leakages Remote smart metering system: the case study of Sant Ferran (Formentera)

Formentera case study: Leaks detection not possible with traditional methods. Unregistered water can now be reduced Remote smart metering system: the case study of Sant Ferran (Formentera) Advantages for municipal services: • By analyzing the 24 daily values of all the metres, useful information is available, providing valuable services to the municipal service indicating possible anomalies in the supply network, small and large leaks, reverse flows, etc... • These data enables the municipal water service analyze hydraulic balances, determining the performance and therefore, acting for the system optimization • Supports town water management plans Remote smart metering system: the case study of Sant Ferran (Formentera) Advantages for end users: • Awareness of water metre behaviour and alarms 24 hours a day • Sant Ferran Residents have remote water consumption monitoring through a mobile App designed by Aqualia (Smart aqua) Formentera Water Smart island

During 2018, this remote reading system will be extended to 2,158 domestic water meters throughout the rest of the island Thank you for your attention
