STREAM 2 – Technology and Innovative Infrastructure Solutions:
Stolen, lost, forgotten…and now the drought
How Water Authorities can take better care of their water.
$
• 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
TECHNOLOGY CAN HELP YOU...
• IoT makes cost effective data collection more accessible than ever• Innovative deployment solutions• Network-wide smart metering solutions now affordable
• 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
NEW TECHNOLOGY – ULTRASONIC METERING
PROACTIVE LEAK DETECTION
• Identifying leaks fast and effectively
• Reduce long term waterloss that costs money
• Avoid infrastructure damage
• Upgraded outdated technologies

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?
