Project 1.2 – Characterization of urban stormwater in Israel
Throughout the world, including Israel, urban runoff is considered to be a nuisance rather than a potential water source, and as such, stormwater is transported out of the cities, and eventually flows into streams or the ocean. Many researchers have shown that urban runoff may contain a wide spectrum of both organic and inorganic pollutants, heavy metals and pathogenic bacteria. The runoff is then likely to pollute the bodies of water into which the stormwater flows. The “water sensitive cities” approach that has recently been developed in Australia sees this stormwater runoff as a potential resource that can be an alternative or additional urban water source, for a range of uses within the city (i.e. close to the place where the rain falls). An attempt to adapt this approach in Israel is the motivation of this research.
