Project Description

JNF is helping to install an innovative stormwater bio-filter system in a highway near the city of Ramla, 20 km southeast of Tel-Aviv-Jaffa.

The biofilter collects, purifies and recycles urban runoff, which is then used for greening the city and recharging Israel’s coastal aquifer. The pilot project includes monitoring, following the implementation of the project.

  • To test models for stormwater harvesting and purification technologies in Israel.
  • To test new stormwater harvesting technology on roads.
  • To quantify recharge capacity of the treated water to the coastal aquifer.

The city of Ramla, in cooperation with JNF, Monash University in Australia and universities in Israel, has installed an innovative, pilot biofilter system along a major highway. The biofilter is a modular system that harvests stromwater from roads, roofs and other conduits and treats the water through the use of filters and biochemical reactions, removing pollutants from stormwater.

Following filtering, the water quality is monitored, tested and the data analyzed in comparison with other biofilters in Israel. The filtered water greens the city, provides an inexpensive supply for gardening, prevents the pollution of groundwater and promotes aquifer remediation, clean beaches and streams and improves the micro-climate. This pilot system together with those in Bat Yam and Kfar-Sava serve as the main research platform to establish policies and processes that will lead to the widespread adoption of cutting edge, stormwater harvesting technologies in Israel

Your donation to the Ramla Biofilter Project will involve you in a state-of-the-art pilot project that aims to create healthier Israeli cities through the optimal reuse of urban runoff. You will be a partner in the innovative and exciting bio-filter technology, with promising ramifications for Israel’s densely populated cities and you will be involved in leading the country towards an environmentally sustainable future.

JNF, the largest green organisation in Israel, leads the country in environmental projects. Where water management is concerned, biofilter technology is a key element in the vision of Water Sensitive Cities, an interdisciplinary applied science program for sustainable urban environments through water management. It is the first of its kind in Israel, introduced by Australia’s Monash University. Israel’s coastal aquifer, an important source of water for domestic use, has deteriorated in recent decades due to over-pumping and the consequent, continually increasing intrusion of seawater. As a result, there is a dearth of water and the quality of potable water has sorely deteriorated.

The biofilter, a unique system for draining and purifying runoff will redress this situation. The pilot project involves the installation a biofilter along a major highway and concomitant research, which includes monitoring the production and quality of the purified water in terms of the system’s efficacy in removing toxic metals, gasoline and oil from vehicles, industrial chemicals and pathogens from sewage.

Monitoring will also determine the system’s economic benefits, such as the reduction in the cost of water for municipal use. The ancient city of Ramla, one of two cities chosen for this pilot project, has been beset by neglect, financial problems and a negative public image. In the long-run, the benefits ensuing from this pilot project are sure to improve its citizens’ quality of life.
