Why does israel treat and reuse industrial wastewater?

ANSWER:

Israel treats and reuses industrial wastewater because it faces water scarcity.

EXPLANATION:

Israel was in fact one of the first nations to encounter the problem of water scarcity when its main sources became exhausted because of overuse and rising population. Because of this, Israel did not have enough water for irrigation and the farmers had to find another water source. Water recycling was the best way that could meet the needs of water for irrigation purposes. Today, all industrial units in Israel need to have an in-house water treatment plant so that wastewater can be treated and effluents can be removed before this water is discharged into the sewage and eventually reused for irrigation purposes.
