Grey Water: A New System to Conserve Water in Israel

June 2, 2009




The leftover water from showers, sinks and washing machines, also known as grey water can be reused in toilets or to water gardens with the correct treatment.  The Jerusalem Post reported that a new project has begun to determine if grey water recycling systems will be effective in conserving water in Israel.  Extensive tests must be done before implementing the system publicly, and a variety of factors will determine if it will be efficient and safe.  In it’s efforts to conserve water, Israel’s Water Authority has been behind the idea for this project for a long time now.

…a study in 2003 that showed that with 20% to 30% of households [not just public buildings] utilizing such systems, the potential annual savings were between 25 million and 50 million cubic meters of water per year. That’s the equivalent of a small city’s
annual water use…

Two different technologies will be tested, one for smaller use and another for larger systems.  The initial testing phase of the project will be in the showers of a Jerusalem mikve.  If successful, the system will then be put in dorms and hotels.  The goal of using a mikve as the first test site is to bring together Judaism and the environment and introduce new groups to environmental issues.  

This unique collaboration of so many different sectors could lead to a great contribution to saving water in Israel. It will add a lot of information not available today and a lot of real-world experience…
