5. AN EXAMPLE: LONDON
UK_WATER SUPPLY UTILITY
15 million customers
2.6 Gl/day drinking water
3 billion $ revenue (2013-14)

6. HOW TO FILL THE GAP?
UK_WATER SUPPLY UTILITY
15 million customers
2.6 Gl/day drinking water
3 billion $ revenue (2013-14)
water demand
available resource

9. THE PROJECT
high resolution water
consumption data
interaction with customers
for socio-psychographic
data gathering
management strategies:
dynamic pricing
rewards
INNOVATIVE WATER

17. WATER CONSUMPTION DISAGGREGATION INTO END USES
Toilet
Shower
Dishwasher
Washing machine
Garden
Swimming pool
ONE MEASURE MANY END USES
Need for fully automated
disaggregation algorithms
overlapping,
simultaneous water
end uses
human-dependent
vs
automatic fixtures

18. A NEW END USE CHARACTERIZATION ALGORITHM
MODEL FEATURES
Factorial Hidden Markov Model
Iterative Subsequence Dynamic Time Warping
MODEL PERFORMANCE
ABLE TO CHARACTERIZE UP TO 4-5 SIMULTANEOUSLY WORKING FIXTURES
