The Biofilter project, already in its fifth year, is continuing to progress and prove its effectiveness in dealing with a water problem most urbanized areas are facing. The project is being carried out by KKL-JNF and Monash University in Melbourne, with the support of JNF Australia.

With increased construction and development in cities, rain water is not absorbed into the ground, which is covered with cement and asphalt, and the rain flows along the streets before draining into the sea, rather than being harnessed as a resource that can benefit cities and neighborhoods.  Sometimes, as little as five percent of rainwater enters the water table in urbanized areas because of this phenomenon.  

In addition, Israel faces the challenge of non-operational fresh water wells due to sea water seeping up to one kilometer into the aquifers along the coastline, making the water saline and unfit for use.

The first engineered green water-treatment system in Israel, the Kfar Saba Biofilter pilot project harvests and treats polluted water. It consists of a shallow basin with a multi-level filter system composed of sand, gravel, and especially suited vegetation which have been selected for their pollutant removal capacities. The entire filtering process can take two hours and the water at this stage can be used for irrigation and sanitation needs.
