A variety of KKL JNF projects related to water were presented at the CleanTech exhibition, the annual international conference for clean water and energy technology, which took place in Tel Aviv this week.  Participating in the event were about 150 companies from Israel and abroad presenting new developments in green technology - solar energy systems, facilities for recycling gray water, motors for more efficient use of energy, facilities for recycling waste, and many more new innovations, which place Israel at the forefront of technology for environmental protection.
There were forums and seminars at the conference on topics such as renewable KKLenergy, water shortage, reduction of greenhouse gas emissions, green construction, recycling, green motor vehicles, and so on.  Among the many highlights at the fair was KKL-JNF's impressive booth, which showcased the organization's work for the benefit of Israel’s water economy: construction of reservoirs and dams, biological water purification, wetlands, water wells and tourism projects.
The many visitors who stopped at the KKL JNF booth were given explanations about the reservoirs all over Israel that were constructed by KKL JNF, which provide about half of the water used for agriculture in Israel today.  The reservoirs also solve the problem of what to do with effluents after treatment, and they also leave more natural freshwater for domestic use.  KKL JNF's river rehabilitation projects include the removal of pollutants, landscape rehabilitation, soil preservation and park development for the benefit of the public.  Among the rivers restored and rehabilitated by KKL JNF, with the assistance of its friends all over the world, are Nahal Alexander, Nahal Kishon, Nahal Harod and Nahal Besor.
KKL JNF has been pioneering in the application of an innovative technology KKLcalled the biofilter, a facility for treating rainwater with biological means.  Runoff from city streets is purified by layers of plants.  This water may then be salvaged for irrigation and reintroduction into the aquifer.  There is already one facility in operation in Kfar Saba, which was contributed by friends of KKL JNF from Australia in conjunction with Monash University, and two more facilities are planned for construction next year.
Another unique project presented was the wetlands project in the Yarkon riverbed.  The effluents from the water treatment facilities in Hod Hasharon and Kfar Saba are purified in a series of pools that serve as habitats for microorganisms that decompose the remaining toxins.  The clean water is then drained into the Yarkon, providing the stream with a constant source of high quality water.  This project is also being undertaken thanks to the support of friends of KKL JNF in Australia, with the participation of the Yarkon River Authority.
A number of new water facilities that KKL-JNF is promoting were also presented at the booth. These include the Shamir Well in the Upper Galilee, which will produce water from an aquifer that has not been utilized until now, and the construction of a manmade lake in Nahal Beersheba Park, with recycled water from reservoirs KKL JNF has constructed in the Negev.  These two projects are being financed by friends of KKL JNF in the USA.
Moshe Cohen, director of KKL-JNF's Projects Development Division, said that water projects are a crucial part of KKL JNF’s work, especially in view of the extended drought Israel has been undergoing.  “It is not by chance that the KKL JNF symbol contains the color blue, which represents our work in water technology,” said Cohen.
