Two fifths of the world’s population faces water shortages. During the coming decades, water scarcity is expected to rise as a result of a rapid increase in the demand for water due to population growth, urbanization and increasing consumption of water per capita. In addition, climate change is expected to influence the supply of water, modifying the regional distribution of freshwater resources.

Governments should foster water recycling, value-oriented water reuse and enforce quality standards.

Water recycling and reuse should be standard practice. Rapid technological development has increased the efficiency and reduced the cost of recycling water. For example, in Israel more than 50% of annual irrigation water supply comes from recycled water. The positive and negative value of substances in (reusable) water needs a market. It is an economic opportunity to use the “waste.”

Governments play a central role in promoting water reuse and enforcing quality standards. Water recycling should be widely promoted not only to preserve water availability, but also as a measure to protect the environment. To give water a price could also accelerate the implementation of water recycling and water reuse schemes and technologies.
