Valencia: water technology capital

EMIVASA combines Big Data, smart meters, sensors and digital twin technology in the management of the drinking water supply network. Current consumption figures during the lockdown are similar to those for a typical Sunday. When people go to their balconies to clap, there is a resulting drop in consumption, similar to that of halftime in a big football match.

Technology at the service of people and their wellbeing. This is how the network of smart sensors in the city of Valencia is conceived. The GOAigua technological solution assumes great importance in the current situation. EMIVASA deploys this technology. Smart meters and sensors, Big Data and our digital twin enables us to act on the network from our control centre, 24 hours per day.

And this technology is also enabling the measurement of public spirit and solidarity in terms of water consumption. And what are the results? Valencians are staying at home and paying heed to the COVID 19-related lockdown measures. Substantial changes are not being recorded in areas in which people commonly have second homes and, at 20h, a drop in consumption is appreciated as the people take to their balconies, like during halftime in a big football match

Every day is Sunday

The change in consumption patterns reveals that people are getting up later. “The first peak of demand is now between 9h and 10h, when it is normally between 7h and 8h on weekdays”, says Juan José Pérez Palomar, Director of Drinking Water Services at Global Omnium and a Director of EMIVASA, the utility responsible for water supply in Valencia. Following this peak of demand, water consumption plummets until midday or lunchtime. “The same trend occurs around dinner time, and water consumption continues for longer as people are going to bed later”, he adds.  

Water consumption figures also reveal that the main beach areas outside the city centre have not seen a significant increase in consumption. “Valencians have not gone to their second homes. They are complying with the lockdown, according to remote reading data”. Pérez Palomar also praises the “responsible consumption” of water being registered, without increases in the average volume. “People are not showering four times a day”.

Going out onto the balcony at 20h has a similar effect to the halftime break in a cup final.

How many people are taking to their balconies every day to pay tribute to health workers? A lot. So many that water consumption falls significantly for a few minutes and rises again when most people begin to prepare dinner or have a shower. “We only note variations of this type at halftime during big football matches”. Speaking on the drop in consumption at 20h, the EMIVASA Director points out that “this was noticeable from day one”.
