Smart Water 4 Europe

• Collaborative EU project

• UK demonstration in Reading

• Vitens, ACCIONA Agua, LILLE 1

• 20 partners total

• UK focus on leakage, energy and

customer interaction

Syrinix PipeMinder devices.

4

PipeMinder-S

• Battery powered (5 years)

• 128 samples/second

• Transmits significant events

• Compatible with pulse output flow

meters

• Display data on RADAR portal

• GPS for accurate positioning

• Other types

− PipeMinder-C (rising mains)

− PipeMinder-T (trunk mains)

What we get.

5

Loads of time series data

• 17 PipeMinder-S devices

• 4 DMAs

• Jan 2016 – May 2017

− 10,572 transients

− 30,000 obs. per transient

− 316 million obs.

− 6.13 GB in CSVs

What we’ve done.

6

Using R (free, open source):

• Scrape data via RADAR

• Pre-processing

• Resampling ^

• Similarity measure ^

• Clustering algorithms ^

• Classification ^

• Visualisation

• Reports/documentation

^ Parallelised

How it’s used.

8

Classification

• Focus on customer

• New transients are transmitted

by PipeMinder devices

• Pre-processing

• Distance to each cluster

calculated

• Assigned to ‘closest’ cluster:

− If meets a tolerance threshold

− Else it is ‘new’ and a point of

interest (POI)

Opportunities

• Instrument a wider area

− More comprehensive

dictionary

• Confirmation

− Engineered scenarios

− Investigate POIs

• Show transients over network

map in a dashboard

• On board processing

− Saves radio use and battery
