In the coming period, the world facing different choices about the role of different societies in protecting environment, encouraging green cities development, and supporting social justice.
Green cities aim to preserve nature resources and the human element more efficiently, while creating healthier, high-performance structures, homes and communities that conserve natural resources.
Wastewater reuse is one of the major resources to provide future water supply in different areas of the world, especially in arid and semi-arid zones, where this can assist to reduce freshwater consumption and availability.

REUSE WASTE WATER AND
GREEN CITIES DEVELOPMENT

2. Introduction
• In nature, water (as energy) is neither formed nor
destroyed but is converted from one form to another .
Only about 1% of global water occurs as liquid freshwater.
More than 98% of the freshwater occurs as groundwater,
while less than 2% is available in streams and lakes, so the
liquid freshwater is a finite and limited resource.
Water scarcity and water pollution are crucial issues in
today’s world. One of the ways to reduce the impact of
water scarcity and pollution is wastewater reuse.

• In the coming period, the world facing different
choices about the role of different societies in
protecting environment, encouraging green cities
development, and supporting social justice.
Green cities aim to preserve nature resources and the human
element more efficiently, while creating healthier, high-
performance structures, homes and communities that
conserve natural resources.
Wastewater reuse is one of the major resources to provide
future water supply in different areas of the world, especially
in arid and semi-arid zones, where this can assist to reduce
freshwater consumption and availability.
24. The reuse of wastewater in green cities reduces human
consumption of fresh water, which conserving fresh water
resources; it also provides environment protection and extent
reduces the level of pollution and thus contributes to the
achievement of sustainable development.
There are different fields of waste water reuse in green cities
such as the agricultural sector, the urban sector as well as for
industrial purposes.
Wastewater can be used in the agricultural sector, such as
"planting forests, irrigation landscaping areas and bio-fuel
trees"
The reuse of wastewater in green cities could avoid the water
crisis in different regions of the world by preserving sources of
fresh water for human use, as well as protecting the environment
from different hazards and achieving sustainable development.
25. Conclusion
• Water conservation and beneficial reuse can reduce
freshwater diversions from streams and improve
downstream water quality.
• Water reuse increases the available supply of water and
enables greater human needs to be achieved with less
fresh water, thus lessening mankind’s impact on the
world’s water environment.
