Meimei Hadarom Agricultural Cooperative Society, one of Israel’s oldest and largest utilities, has successfully implemented Arad’s water management solutions.
With the implementation of Arad’s Multi Jet type and Octave water meters integrated with the Dialog 3G system, Meimei Hadarom succeeded in substantially improving its water management abilities. The water utility can now remotely collect data on the water consumption of each customer and improve leakage detection, thus saving significant amounts of water and energy.
The project has resulted in a sharp rise in the corporation’s revenues (an increase of more than $1 million annually since the project began). Moreover, water loss has dropped from 8% in 2006 to only 2% in 2012, which translates into overall savings of 1.2 million c/m a year.
The overall operational effectiveness of Meimei Hadarom has significantly improved as the company managed to substantially increase revenues, reduce the non-revenue water dramatically and improve its relationship with customers.
“Arad’s system has drastically improved information availability over water managed by the cooperative. Previously, apart from monthly readings of our water meters, we did not collect data at all,” said Yoav Cohen, CEO of Meimei Hadarom. “Today, thanks to Arad, we are constantly updated on a day-to-day basis on water consumption, alerts, tampering and leaks, and can respond immediately to every problem that occurs.
Meimei Hadarom, based in central Israel in the city of Ramla, supplies water for both residential and agricultural purposes. The utility provides services to some 44 kibbutzim and agricultural communities. It purchases some 20 million cubic meters a year, which is the equivalent of almost half of Tel Aviv’s water purchasing. Despite that, the average annual consumption per meter in Meimei Hadarom was extremely high and stood at 1,538 c/m, some 30 times higher than Israel’s average of 60 c/m per meter).
In an area which is dominated by both urban and rural communities and high levels of water consumption, Meimei Hadarom needed a solution that would allow it to accurately measure water consumption, improve leakage detection and support water, energy and money savings.
Meimei Hadarom faced some serious challenges, including a high percentage of water loss (8%), equal to more than 1.2 million c/m a year. In addition, it suffered from high levels of non-revenue water and a relatively high number of unread meters located in isolated, hardly accessible locations, and old meters which could not be found. The utility also faced water theft and dissatisfied consumers who complained about the service level and low transparency.
In 2006, Meimei Hadarom started to install Arad smart meters and systems. This included replacing the old, existing consumer and bulk water meters with new Arad 3G meters. The system was optimized, ensuring that the meter’s size matched the actual usage and oversized meters were replaced. The project included upgrading the overall water infrastructure and the replacement of old and unsuitable water pipes.
In addition, every community was divided into a few sub areas called DMA (district metered area). In each subzone, the Arad MDM software compared water consumption as measured by the main meters with consumption of sub meters. Once a difference was tracked, the system immediately alerted the control center.
“The service to end users has substantially improved since we introduced the new system. We have notified our clients about leakage in their homes that previously had gone unnoticed for months and years. We have saved these users much money and we have received a very positive response since we introduced this service, which is carried out solely by the system,” Cohen said.
To date, 37 villages and kibbutzim are using Arad’s solution and by 2014, the project will be completed.
