Sanitation
Israel generally has a modern sanitation system particularly in major Jewish towns and cities. However, a report released by the Israel Union for Environmental Defense in 2010 found that 500,000 homes in Israel are not linked to a central sewage system. The vast majority of the 150 communities are Arab communities that are have no sewage hook-up and whose waste is therefore expelled into cesspits or the local environment. Jerusalem and Ariel were reported as dumping some of their refuse into streams. Israel's Water Authority said that Israel is in the "top spot globally" for using treated waste and that only 2.7% of raw sewage flows into streams and none into the sea.
