Arad Metering Technologies Conserves Water via Battery-Operated Drones

The word drone may sounds related to any contemporary sci-fi flicks, or images of attacks carried out remotely on hostile lands, or even your high-school biology teacher’s voice. We don’t expect a drone to help us save water, but that’s what Arad Metering Technologies intends to do. The Israeli company’s battery-operated drone is one of the novel tools it’s deploying to help consumers and companies conserve H2O — and to make money.

Such an idea would come out of Israel is no coincidence. The country is poor in water and rich in tech innovation, much of it born of constant military conflict. Israel pioneered the use of unmanned aerial vehicles after it lost many fighter jets in the 1973 war. But Arad’s drones don’t fight: They read data from the company’s patented water-meter system to detect leakage or, in irrigation systems, drought.

The World Bank estimates that water wastage costs utilities $14 billion a year worldwide; in developing countries, 200 million more people could be served by the water lost to leaks and theft. Arad CEO Dan Winter says this is largely a consequence of how the business works in places where water is cheap or untaxed: “You train people to abuse water because they pay very little.”

With this innovation, instead of meter reading – it can provide real time monitoring of water supply infrastructures. Its technology can find irregularities — a pipe failure, an unusually low flow rate, or a too-constant one that could indicate a leak — in a few hours, rather than every 60 days as with a typical meter reading.

Arad’s system is built around what looks like a standard meter. The difference is on the inside, where you’ll find 3G wireless technology, a microcontroller, and 20-year batteries. Every 11 to 30 seconds, the system transmits data, which can be picked up by a drone (best for quickly covering big distances in remote areas) or by a drive-by or fixed-base reader. The data are then analyzed by computer to gauge how much water has been consumed, how much was lost, and even where tampering may have taken place. As a result, companies can save both water and man hours.

The possibilities for Arad’s services go far beyond water should be covering abilities to monitor everything from municipal infrastructure, such as traffic lights, to security-camera networks — basically any complex system prone to localized failures and waste. Arad has its own way, to proof drones could be associated with saving, not destroying; life, not death.

Automated rain barrel watering system

To some crowds, irrigating a small garden is a relatively relaxing and sometimes therapeutic activity, well if you are a botany/biology nerd or desperately really need a hobby – but going away for any length of time can present a problem. The simple solution of course is to purchase a hose-bib/timer package from Home Depot for about $30 and set up a small drip system to efficiently water each plant or row of plants (rather than a wasteful sprinkler system). Going along with conserving water is using a rain barrel collection system to capture rain for later use thus eliminating or more likely reducing treated water consumption.

Adding a rain barrel complicates the system significantly as there isn’t much water pressure at its spigot compared to a standard city spigot which has somewhere around 40 psi. Also, if the barrel is empty, you don’t want your plants to die and thus you need to be able to detect that the barrel is empty and switch to city water.
