backgroundreasons to install

As part of its Green City initiative the Municipality of Ashkelon (a city in southern Israel with a population of around 100,000) included water conservation as one of its primary objectives. Drought is an ongoing nationwide problem and the Ashkelon Municipality recognized its responsibility to combat water wastage through undetected leaks and inefficient usage. Another goal was to immediately cut the cost of water consumption. Schools were identified as a major culprit in water wastage as children do not close faucets properly and there is generally low maintenance of infrastructure, especially after school hours, on weekends and during vacation periods. While looking for the most cost effective solution, the Municipality was introduced to the Triple+ CLM™ system which they decided to install in their schools. The Triple+ system, which is based on IoT technology, was chosen as it met various criteria. The battery operated, wireless shutoff valves assure immediate installation without the need for costly cable trenching. The shutoff units are programmed to certain opening/closing hours according to the school schedule. Additionally, the shutoff units are connected to the Hub that communicates with the Triple+ Cloud.
This enables 24/7 monitoring from a central location for real time status updates via a mobile phone or the municipality command and control room. The Triple+ device fully met the Municipality’s checklist of requirements topped by tight budgetary constraints. As water is saved immediately when the shutoff system is programmed for set hours, a ROI (Return on Investment) is achieved within days of installation. Longevity of the device was another concern as it needed to be placed outdoors in a harsh climate. The Triple+ device guarantees full operation in all weather conditions as it is manufactured from UV supported, solid reinforced plastic.

the solutionhow did it work

At Municipal School D, the Triple+ CLM™ system was installed in the plumbing system of the agricultural studies area. The valve shutoff was automatically set to operate from 20:45 p.m. to 5:00 a.m.
As a result the amount of water used daily went down significantly from 23,760 to 18,480 gallons. Accordingly, plumbers were called in to detect water leaks. After a leak was detected in a pipe situated 6’ under ground, the water consumption was significantly reduced from 23,760 to 6,600 gallons a day. This immediate reduction of 17,160 gallons of water per day resulted in a monetary saving of 68$ per day or over 2,000$ per month – a ROI (Return on Investment) accomplished within a matter of days.

The Triple+ CLM system was also installed outdoors at Municipal School A and the valve shutoff set from 7:00 p.m. to 7:00 a.m. This resulted in a reduction in daily water consumption from 19,800 to 10,500 gallons. A leak was detected by the system and after repairs were made the water consumption went down further to 5,200 gallons a day. This immediate reduction of 14,600 gallons of water per day saved the Municipality US$58 per day or over 1,700$ per month.

The results of the pilot program were conclusive and accordingly Triple+
was requested to install their systems in all the Municipality’s school system.
Evaluating the success of the pilot program in the initial two schools, the municipality reported a significant drop in the amount of water expenditure as a result of the system’s efficiency in these two locations.
Mr. Avi Buskila, Manager of the Energy Efficiency Department of the Ashkelon Municipality expressed his appreciation for the successful cooperation between his department and Triple+ to improve water conservation in his city and lower expenditure.
