As of August 2009, Tel Aviv Municipality is publishing the Water Quality tests being held periodically.

The results are accesible to the public, including the Yearly Water Quality Report, the periodic tests and the Maintenance Procedure for Water systems in High rise Buildings.

About 90% of the water supply in Tel Aviv is provided by "Mekorot", while the rest 10% are self-provided by water wells in the area.

The Water Quality Report for Year 2009 is attached in the link below.
