Optimized meter management for water supply by EMAYA balearic municipality
Smart Water Metering for Palma de Mallorca
Optimized meter management for water supply by EMAYA balearic municipality
Water
EMAYA
Palma Spain
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.
Meters replaced in line with the
criteria specified by the tool showed 8 times more revenues than meters
replaced using the former replacement criteria, based mainly on age.
23% reduction in metering error
from 3.9% to 3.0% in less than three years.
The identification of a meter brand
registering lower values than the average.
Proof that advanced algorithms can
help facilitate the transition towards smart metering from an economic
perspective.
Monitoring of hardware alarm
information from smart systems, to detect anomalous or even negative
consumption, and to verify that the new meters reduce water losses.
Tool for the analysis of huge
amounts of data as there are daily and even hourly consumptions.
