EMAYA is a public company, fully owned by the Palma City Council municipality. Its role is to manage the public services relating to the integral water cycle (supply, treatment, sanitation and reuse), collection of urban solid waste and street cleaning. ​ Optimized meter management has been always a priority at EMAYA, which has the only meter testing laboratory in the Balearic Islands. 

• In 2018, EMAYA’s water division began a process of analysis as part of a strategic vision that would lead them to roll out a smart metering implementation project in 2021, with the aim of equipping 100% of Palma with smart meters. 
• Water is a scarce and valuable resource in Palma. Climate change, growing levels of tourism, and the continued development of the island are amongst the factors that are aggravating the water scarcity situation. Desalination plants usually reach the limit of their capacity during summer. 
• The plan for the future was migration to smart metering.

SIWA Meter Data Analytics (MDA)

• Integration of data from almost 100,000 water meters with bimonthly readings. Historical readings of each water meter were included (meter size, meter type, installation date, activity, etc.). 
• The performance of 11,280 replaced meters was studied over a 10-month period, to verify that the advanced algorithms used by the tool could help in the future transition towards smart metering. 29% of the new meters were replaced at the suggestion of the tool.​
