SMART water distribution networks

The art of the possible

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..

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

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%

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?

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 BIG QUESTIONIs the water industry supply chain ready to leaves their egos at the

door and deliver this to UK water plc?
