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
@WATERNOMICS_EU www.waternomics.eu11
INCREASE AWARENESS - RESULTS• 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)

@WATERNOMICS_EU www.waternomics.eu25
IMPROVE OPERATION - RESULTS
• 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
@WATERNOMICS_EU www.waternomics.eu27
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
@WATERNOMICS_EU www.waternomics.eu28
GALWAY PILOTS - CONCLUSIONS
CONCLUSION COMMENT
High Profile Display of Current Water Usage Number Very Effective
Creating significant discussion andcommentary 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 andinformation 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 awarenessresult from high baseline also in public building motivation for change is less clear
@WATERNOMICS_EU www.waternomics.eu29
