INCREASE AWARENESS - RESULTS
• Pre and post intervention surveys undertaken at pilots to measure water
conservation behaviour;
• Pencil and paper questionnaires developed based on Norm Activation
Model (NAM; Schwartz, 1977) to explain altruistic pro environmental
behaviour;
• NAM looks at problem awareness (PA), ascription of responsibility (AR) and
outcome efficacy (OE) and how these relate to personal norms and
behaviour;
• Responses measured on 5 point scale where respondents chose a
response from strongly disagree (1) to strongly disagree (5) to a statement;
• Also measured – Personal Norms, Existing Behaviour, Intention to
Participate in promotion

• Example of question to measure PA (1 of 3 Relating)
• Example of question to measure OE (1 of 5 Relating)
• Example of question to measure AR (1 of 4 Relating)

at NUI Galway developing real time monitoring
solution for existing mechanical meters (OCR /Pulse);
• Project planned in March 2017 to construct laboratory
model of building potable water network to examine
effect of retention time on water quality under various
conditions;

Biggest Water Consumers – MAINS WATER SUPPLY (MWS)
60 - 75 % of
CWS supplies
rainwater tanks
25 - 40% of
CWS used for
Taps & Showers
Flow Signature Application - Eng Building Showers – 15-20 showers per day approx. Average shower
time is 5.8 minutes with a min and max of 1.5 - 15 minutes respectively. Average shower uses 200 litres
with a min and max usage of 50 and 660 litres respectively.

Baseline Water consumption established at
Coláiste na Coiribe Pilot Jan-June 2016

Coláiste na Coiribe – Faults Identified
Exceedance of Baseline/Unexpected Flow

• Significant usage identified on MWS (WM001) at approximately 15
m3/day (0.64m3/hr) - Continuous Flow
• Treating the water mains as a dendogram, each water main meter was
investigated using a top-down hierarchal rule-based approach to identify
the continuous flow signature.
• Continuous flows signature of Fault 1 was detected in the rainwater
harvesting top-up line.
• Greywater tank supply to the building was found to be continuous during
this period. Suspected to be a leak/faulty toilet cistern.
• Fault was reported to management in mid-March and was resolved on
the 31st March.
• Fault coincided with a dry period resulting in the use of costed mains
water as opposed harvested rainwater (239.24m3) .

LINATE-CONCLUSIONS
CONCLUSION COMMENT
Waternomics Information Platform
Very Effective
Increase awareness among the airport
managers and staff of normal usage -
usage enabled identification of potential
problems
Managers are interested in the
Waternomics Information Platform
Interest in maintaining the platform for
the Linate airport
At Linate interactions with Public
Dashboard touch screen displays was
very successful
More than 2000 users attracted.
Personal water footprint calculated and
feedback released
Great interest in Fault detection and the
possibility to perform hydraulic
simulation in a easy way
Staff at Linate acknowledge that useful
for detecting faults at an early stage
saving water and money

THERMI - CONCLUSIONS
CONCLUSION COMMENT
Increase in awareness confirmed
by end users
The apps helped in understanding their water
consumption
Users started thinking changing
specific behaviours
In some cases users reported that it affected
some of their decisions (especially the choice
between washing dishes in the dishwasher or
by hand)
Users became familiar with
different water usages and their
effect (e.g. water footprint)
Although challenged that we are looking only
at water and does not include other
environmental dimensions such as energy
Relative peace of mind for faults If measurement was in the mains supply it
would be even better
Increased interest in adopting
more smart home technologies
Especially for power consumption which is
more expensive
In busy households water is not
a high priority
Water is inexpensive and therefore not high on
the list that affect the budget of a household

GALWAY PILOTS - CONCLUSIONS
CONCLUSION COMMENT
High Profile Display of Current Water
Usage Number Very Effective
Creating significant discussion and
commentary from staff and students are
aware of scale of volume
Managers are interested in concept and
outputs of platform but cannot prioritise
above emergency issues
Ensure that access to dashboard and
information is as easy as possible –
desktop icon/ weekly update
At NUIG and Coláiste na Coiribe,
identification of faults very successful
Faults that would otherwise remain hidden
are now being identified, limitations on
maintenance budgets is issue
Consider water usage as Operation or
System controlled and User controlled
In a public building behavioural change in
staff and students will be overshadowed
masked by system controlled consumption
Water awareness baselines are high and
post intervention results show increase
only in junior cycle students
May be difficult to increase awareness
result from high baseline also in public
building motivation for change is less clear

FINAL REMARKS
• Operational alert system in place for water retention
exceedance in potable water network NUIG
• Public dashboard to be maintained in NUIG Pilot and
developed as part of water/energy studies
• Significant faults identified in CnaC Pilot (3) and Engineering
Building Pilot (2)
• Extension of piloted systems from Linate Airport to Malpensa
airport
• Flow signature methodology developed & applied
• Some gains in awareness with secondary school students
