Monash University has been experimenting with biofiltration methodology for nearly a decade. Under the leadership of Professors Tony Wong and Ana Deletic and with an incredible team of engineers, town planners, and social scientists and in collaboration with other universities, government and semi government departments and industry, Australia now leads the world in the technology of capturing and purifying storm water run off.
In Israel, rainfall in winter accounts for approximately 70% of the total water consumed domestically. Most of the water falls on built up areas and is captured in storm water drains and unlike years gone by, instead of slowly penetrating the surface and replenishing the aquifers it flows out to sea.
By introducing Biofiltration it is intended to:
• Capture, purify and pump storm water back into the aquifers
• Pump up polluted water, run it through the biofilter and re-pump it back into the aquifers for use.
Our first experimental biofilter has been completed in Kfar Saba and is due to commence operating in September 2010.
In addition to replenishing the aquifers the advantages of biofiltration over other forms of water purification are:
a) Prevention of pollution by storm water flowing into coastal areas
b) Greening of built up areas resulting in micro climatic change by reducing summer temperature by up to 4-5C, thus reducing demand on electricity and increasing the “life” of roadways
c) Aesthetic improvement to built up areas
The introduction of biofiltration is a preliminary step in radical improvement to 21st century town planning to improve quality of life for all Israelis. It is intended that it will play a role in bringing to Australia Israel’s world leading use of rural use of water.
