ANSWER:
Israel treats and reuses industrial wastewater because it faces water scarcity.
Step-by-step 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.
