SMART water distribution networks
1. Do “we” want them?2. What qualities does UK water plc want? 3. What might it look like? 4. Why, and why now?5. How do we begin to get there?

SMART water networksIndustry is on a flightpath towards SMART
The water industry is awash with talk of SMART water networksSensing, data collection, data analysis are fundamental to this journey

Could a SMART water network look a bit like this?
SMART water networks
Why now?
The stars have aligned..
The stars have aligned..
Cloud based data storage is cheap, secure and readily availableCloud based platforms offer massive connectivity possibilities
The art of the possible
The art of the possible
Communications are faster and more reliableNB-IoT, LoRa
5G is coming and its going to be fastGetting data from where its measured to where its analysed will be quicker, easier
The stars have aligned..
The art of the possible
Processing power is growing and now enables processing of massive data sets real timePower grows more each HOUR than it did in the first 90 years……
The stars have aligned..
The art of the possible
Powerful models and algorithms existMachine learning is mature
AI is advancing rapidly
The stars have aligned..
The art of the possible
SMART water networksWhat’s the missing part in the specific case of water quality data?
Data comes from sensors
The art of the possible
SMART water networksUntil recently network water quality monitors were:
❖ Relatively large❖ Expensive❖ Power hungry❖ Maintenance intensive
2008
The art of the possible
SMART water networksNow they are:
❖ Much smaller❖ Less costly❖ Power efficient❖ More reliable
2018
Future possibilities. Hydrants within DMA
Future possibilities. PRV installs
Micro turbidity as precursor to event
The art of the possible
1. Small non normal turbidity eventsNot an issue in isolation but….
2. Occurred two weeks before a burstMost likely cause was a transient causing an NTU spike, fractured pipe which then burst
3. One smaller water company has an ODI 10 minutes per customer per year interruption. £483k penalty. Equates to 5 million minutes. Just one recent 5 hour interruption to 1000 homes was 6%
The art of the possible
How useful would it be to have real time pipe condition monitoring, flow meter calibration?
Location Peak Value ppm Time of peak Time difference hh:mm
2390 0.97 23:52 00:00
2590 0.93 00:22 00:30
2690 0.85 01:13 00:51
4701 0.73 03:41 02:28
Residual chlorine as a tracer and pipe condition monitor
The art of the possible
1. Peak to peak can be used for time/flowUseful for model calibrationValidating flow meters, replace flow meters
2. Cl2 values can be used for chlorine decayChanges in decay give insight into condition of pipeOptimise models
3. Feedback to WTW to optimise dosing 4. And, and , and………????
SMART water networksHow are we going to bring this together?
1. Collaboration2. Business model innovation3. Collaboration4. Openness5. Collaboration

The art of the possibleSmart Water systems are within reach
All the technologies are already in use
The platforms are safe and reliable
The analytics tools are there and just need data to be improved
We have a good idea what we want
We understand the benefits
The art of the possible
THE BIG QUESTIONIs the water industry supply chain ready to leaves their egos at the
door and deliver this to UK water plc?
