Stolen, lost, forgotten…and now the drought
How Water Authorities can take better care of their water.
“IT'S SO DRY THE TREES ARE BRIBING THE DOGS.”
WE’VE BEEN THERE BEFORE…
BUT WHAT HAS CHANGED?
$
• We’re still losing 10% of our water in our networks and thinkthat’s “normal”
• We’re still checking our water meters only once every 3 months
• We still have leaks and other abnormal use going undetectedfor months in our facilities and buildings
• We still complain that we can’t do better because “it’s tooexpensive” – when in fact it isn’t
So what next?
THERE’S A HOLE IN MY BUCKET PLAN
FIX IT…
SMART MONITORING OF WATER THINGS WITH IOT
• IoT is revolutionising the water industry
• Water Industry is all about the reliable and safe management and distribution of water
• Huge assets, few monitored
• Focus has been on treatment plants, but what about pipes and networks?
• Water ‘things’ often difficult to access
• Historically lacked economically viable 24/7 monitoring solutions
LOW POWER + LOW COST = EASY (AFFORDABLE)
Water ‘things’ typically don’t have power available
LPWAN ideal for smart water metering:
- Low power consumption
- 2 to 10km range (urban)
- Signal penetration
- Optimal data packet size
- Low capex and opex
THINK LONG TERM, NOT ‘DROUGHT TERM’
TECHNOLOGY CAN HELP YOU...
• IoT makes cost effective data collection more accessible than ever• Innovative deployment solutions• Network-wide smart metering solutions now affordable
OUT WITH THE OLD…
Smart Water MeteringTraditional Metering
• No moving/wearing parts = less faults
Faults are expensive due to high labour costs
• Higher accuracy = reduced NRW
• Additional 2% to 5% of water use recorded.
For a larger utility, this is $ millions of additional revenue
• Integrated register and communications = no reading errors
• Smart water metering requires electronics and batteries.
There are cost efficiencies in combining smart metering and ultrasonic metering

LG NSW WATER DIRECTORATE AMR GUIDELINE
• Now easier than ever to interoperate various technologies.
• 3G and NB-IoT essentially same benefits but NB-IoT far cheaper.
• Cost advantage for technology where network is there already.
• Establishing a network adds a significant cost, especially in country.
• Based on cost only, manual meter reading remains cheapest as “honest” annual O&M costs of AMR/SM systems are similar.
Thus: Comes down to Benefits.
• Single Vendor and LoRaWAN systems are similar in capital and O&M costs and benefits to those of Sigfox.
• Closed Single Vendor systems do not provide significant smart city benefits such as flexibility, expandability and interoperability.
• Drive by systems offer little to no cost advantage with few additional benefits. It could thus also be considered a technology whose time has passed.
• GPRS/3G is no longer a cost competitive technology. NB-IoT offers a no-compromise solution to digital water metering

BUILDING THE BUSINESS CASE
If Smart Water Metering costs $1.00, where will you find the value?
• Avoided leak rebate xcx cents
• Reduced non-registered water xxx cents
• Improved customer engagement / satisfaction / business reputation (PR value) xxx cents
• Defer the time where you run out of water – more chance for rain to fill the dam again. Benefit: xxx cents vs new sources
• Deferred capacity upgrade costs (marginal cost benefit) xxx cents
• Deferred peak flow upgrade costs xxx cents
• Cheaper way to get pressure readings xxx cents
• Reduced NRW xxx cents
• Reduced OHS risk xxx cents
• Net savings from AMR v manual v annual comms cost xxx cents
• Improved billings – better cashflow, less arguments xxx cents
• Exceeding deliverables from grants (higher savings locked in forever as opposed to 3-6 months roving) xxx cents
• Net O&M cost impact (savings due to less troubleshooting, no moving loggers, setting up a new etc.) xxx cents
• What else?
