Increases in water treatment technology have made water recycling a viable engineering solution to water supply limitations.

In the face of intensifying stresses such as climate change, rapid urban population growth, land use change, and public concern with rates and use restrictions, water management is becoming increas

The sustainability of urban water systems is often compared in small numbers of cases selected as much for their familiarity as for their similarities and differences.

Combined Sewer Overflow (CSO) infrastructure are conventionally designed based on historical climate data.

Ensuring future water security requires broad community support for changes in policy, practice, and technology, such as those involved in delivering alternative water schemes.

Training and capacity building are long established critical components of global water, sanitation, and hygiene (WaSH) policies, strategies, and programs.

Low-cost by-products from agricultural, household and industrial sectors have been recognized as a sustainable solution for wastewater treatment.

This article highlights the winning proposals of the first edition of the Elsevier Foundation Green & Sustainable Chemistry Challenge. The winning proposals were chosen for their innovative green chemistry aspects and their large positive impact on the environment, contributing to SDGs 6, 12 and 15.
