A case study on why IoT water metering makes sense, even in remote NZ

Arthur D. Riley & Co Ltd (ADR) is one of New Zealand’s most experienced fieldsmart technology companies for the Utility industry. This is the story about the challenges and benefits of one of their first IoT projects.

New Zealand is generally not short of water, so not the first place you would think of for monitoring water consumption. However some areas of the Country experience water scarcity, especially in the hot summer months. This is the case for Duvauchelle, a small town of mainly holiday homes situated at the head of Akaroa Harbour on Banks Peninsula, an area service by the Christchurch City Council (CCC).

As a beach-side holiday town the population of Duvauchelle triples in the summer months, and so does the water consumption. To the point where water is brought in by truck to cover the essential needs of the inhabitants, at a very high cost to the CCC.

Clearly the town was under “water stress”. With the advent of IoT and the SIGFOX New Zealand National Network there was technology available with near real-time metering of the water consumption, enabling the CCC to better understand demand and potential water leaks. ADR was appointed to help with designing and implementing this smart technology.

The objectives were very clear: previously water meters in the settlement were read once every two years. The CCC now wanted six reads per day to better identify potential over-consumption patterns, high users and leaks. Overall, they wanted to get greater visibility of water usage as well as share the data with wider stakeholders (community and water utilities).

A few challenges presented themselves with project. The area is quite remote with limited cellular coverage, so the use of IoT technology required the installation of a wireless network base station in the right location to cover for the hilly terrain. Also, the water meters were below ground level  and had to be secured under heavy duty plastic or metal lids (reducing radio reception quality of wireless sensors). To add to the difficult, the project had to be completed in difficult weather conditions.

water meter installation sigfoxWorking in conjunction with ADR, Thinxtra installed a solar powered Sigfox base station on an ideal high point in Duvauchelle. ADR then retrofitted 266 water meters in town with IoT pulse dataloggers, and started monitoring consumption data from each water meter via ADR’s bespoke water management platform.

Within a few weeks, ADR were getting some interesting insights, which needed to be checked live. For example, sites with hidden connection to the main pipes, householders diverting pipes before the meter, people removing their dataloggers, trucks passing by and refilling from CCC water tanks, overflowing water tanks, and the usual 10% leakages.

From the beginning of the project, based on the difference between sourced water and the captured water from the meters, 60% of the water was missing. By going through each individual meter consumption insights and determining the real issues on site, and at the same time fixing them over a three month period, they were able to reduce the unaccounted water figure to 30%. This 30% unaccounted water loss will reduce further as more leakage issues on the network are identified and fixed.

Bruce Franks from A.D.Riley commented: “From now on, not only are the users properly allocated their consumption, but Duvauchelle doesn’t require as much water to be brought in by truck during summer, a previously highly inefficient and costly exercise for this small, remote place. From this early experience in dealing with IoT smart metering, ADR and the CCC have gained a lot of insights on consumer water consumption in Duvauchelle, such as previously unknown major leaks, unaccounted for home and commercial excess water usage – gains that could be easily replicated to larger scale projects in an even shorter period. “ Additionally – “This project also enabled ADR to develop PowerBI dashboard for analytics which has been instrumental in solving leakage and loss identification”

Mandurah (WA) is Sigfox Ready to Detect Water Leaks

The City of Mandurah, a Liveable Community award winner and one of the most advanced regional city in Western Australia, is now fully covered with Sigfox LPWAN network, installed, monitored and managed by Thinxtra Australia at no cost to the city.

Among the first IoT projects implemented by the City of Mandurah, to maintain that status of liveable city, is better monitoring water consumption and detecting water leaks by visualising water flow rates in water meters located at Council facilities.

The solution includes Sigfox ready dataloggers retrofitted via reed switch to the water meters, the data is sent via Sigfox IoT network to the WaterGroup data analytics platform (Envisi) to visualise the data with the ability to alert staff if water leaks are detected or if deviations in normal water consumption occur.

The potential benefits are obvious: improve water use in the City’s facilities, reduce water usage cost and nearly remove time consuming water meter inspections.

Sean Hutton, City of Mandurah, commented “In this case it means we can react to water leaks and abnormal water consumption as soon as it happens, instead of having to wait for the next utilities bill to discover an issue. This project aligns perfectly with our Waterwise council program in improving water use efficiency within council facilities and the community, and also has a direct benefit to council in reducing water usage costs.”  

Guenter Hauber-Davidson, CEO of Watergroup, the provider of the solution, also added “It’s always great to work with a client ‘who gets it’. Mandurah is one of those instances where a Council has clearly seen how WaterGroup’s Sigfox based smart water metering solution creates real value for them. By fully embracing the system and from initial results received so far, the City expects the system will be paid back in the first year. For those who do not have these types of house resources available on a consistent basis, there is the WaterGroup AWARE Service. Here the company actively monitors a client’s water use and chases up abnormal use or leaks.”

Such project was made possible in a very short time thanks to the support of Thinxtra who covered the city with the Sigfox wireless network within few weeks via its Smart Council Program. “By enabling councils to trial new solutions risk free, they can experiment with new services and gain real- life experience and understanding of IoT. Clearly, the Smart Council Program brings numerous benefits. There is no catch: At worst, councils will learn about IoT opportunities. At best, councils will create efficiencies and benefits for their citizens.” said Regis Berdaa, BDM Smart Councils at Thinxtra
