The gap between water supply and demand is growing
worldwide, especially in nations such as China that
are undergoing rapid economic development. Wastewater
reuse offers a potential solution to help alleviate this
crisis, essentially providing a "new" source, i.e.,
reclaimed water, for industrial production and agricultural
and landscape irrigation while decreasing the
pressure on high-quality supplies.
A wastewater reclamation system was designed for
the Taocheng District of Hengshui (TDH), China,
which is suffering both a water crisis and financial
limitations. The project incorporates a sewage treatment
plant, natural waterways, and constructed wetlands.
In addition to providing treated effluent for use
as cooling water at a power station, the proposed
system would help revitalize the existing wastewater
treatment plant, enhance the local landscape with a
wetland environment, and promote land values in the
area. A cost-benefit analysis indicates the economic
and noneconomic benefits of the project make it a
viable and sustainable solution for TDH and other
regions facing water shortages. Includes 25 references, tables, figures.
