The environmental benefits of water recycling and reuse
TLDR
Water reuse increases the available supply of water and enables human needs to be met with less fresh water as discussed by the authors, and water reuse case studies in agriculture, urban areas, industry and water resource supplementation in Australia and other countries.Abstract:
The world's supply of fresh water is finite and is threatened by pollution. Rising demands for water to supply agriculture, industry and cities are leading to competition over the allocation of limited fresh water resources. This paper examines how water reuse increases the available supply of water and enables human needs to be met with less fresh water. The paper is illustrated with water reuse case studies in agriculture, urban areas, industry and water resource supplementation in Australia and other countries. The links between water reuse and sustainable water management are examined. Water conservation and water reuse produce substantial environmental benefits, arising from reductions in water diversions, and reductions in the impacts of wastewater discharges on environmental water quality. Some examples are presented demonstrating the environmental benefits in quantitative terms. The paper also describes the economic and environmental benefits identified in a number of recent integrated water cycle planning studies in Australia.read more

Circular economy model framework in the European water and wastewater sector
TL;DR: In this paper, the authors present a new circular economy model framework in the water and wastewater sector, which includes the six following actions: reduction, prevent wastewater generation in the first place by the reduction of water usage and pollution reduction at source, reclamation (removal), reuse, reuse of wastewater as an alternative source of water supply (non-potable usage), recycling, recovery of water from wastewater for potable usage, recovery, rethinking how to use resources to create a sustainable economy, which is ''free` of waste and emissions''.

Integrated water management: emerging issues and challenges
TL;DR: Water short countries can save water by importing most of their food and electric power from other countries with more water, so that in essence they also get the water that was necessary to produce these commodities and is virtually embedded in the commodities.

Selection and Implementation of Nonpotable Water Recycling in “Silicon Valley” (San Jose Area) California
TL;DR: The South Bay Water Recycling, a non-potable water recycling project in the San Jose, California (USA) area, was commissioned in 1998 to supply up to 60,000 m3/day (15 mgd) of high-quality treated effluent to nearly 200 customers for irrigation and industrial use as discussed by the authors.
