Special Issue Information

Dear Colleagues,

Water resources are under increasing pressure to meet the demands of an ever-growing world.  The disproporsionate natural availability of water resources creates uneven access for many populations.  This, combined with the effects of climate change and the cumulative effects of pollution on the natural environment, have pushed some communities to the brink of water security.  The sustainability and vibrancy of many populations are directly tied to the availability of clean water at the household, commercial and industrial levels.

The focus of this special issue will be to highlight the state-of-the-art research being undertaken to improve the access to and use of water, while reducing the pollution footprint associated with human activity.  This will include a link to the socio-economic aspects of water.

The scope of this special issue will include the full cycle of water use, including tbe protection and enhancement of source-water, innovative and efficient public and private water systems, the built environment, and sustainable wastewater treatment.  In addition, efficient industry water taking and re-use, as observed in commercial process water and agricultural irrigation will be included.  Finally, the link to human populations, both with respect to water governance as well as on a health and socioeconomic level will be covered.

This issue will invite a range of papers which include novel reviews of existing literature, laboratory and field-scale studies, as well as qualitative investgations at the individual and population levels.  This issue will also encourage the submission of work which spans disciplines and brings together multiple sectors which interconnect in the larger picture of water sustainability (For example, the Water, Energy and Food Nexus concept)

The purpose of this special issue issue is to bring together ideas and researchers from a variety of backgrounds, to further the many facets of water sustainability.  The anticipated impact of this issue is to spur further collaborative discussion and research into water sustainability, to bring real change at the community level, for populations around the world..

Non-Potable Water Quality Assessment Results for Water Conservation in the Context of a Medical Facility Case Study

This paper discusses recycled non-potable water (NPW) quality test results from an existing, decentralized, treated air handling unit (AHU) air conditioning (A/C) condensate water (CW) system in a medical facility case study (MFCS) in Abu Dhabi (AD), the capital city of the United Arab Emirates (UAE). The MFCS, a 364-bed hospital that opened in 2015 with 50% landscaping, is targeting 100% non-clinical/non-potable water use for landscape irrigation (LI) from 179,700 m3/year treated CW, which is a by-product of AHU A/C. For seven months per year, however, a deficit of 14,340 m3 AHU A/C CW occurs, so costly and non-sustainable, desalinated potable water is required. The proposed change project, using a mixed methodology, develops a sustainable NPW strategy, including a protocol to extract water from recycled, onsite, organic food waste, fire sprinkler pump test water (FSPTW), and reverse osmosis reject water (RORW) to meet the AHU A/C CW shortfall by adapting, enhancing, and monitoring the medical facility’s NPW treatment system. The hospital’s sustainability strategy implemented by the author could be legislated and mandated by the relevant authority for regional medical facilities, taking the form of a water conservation protocol including the classification and characterization of different types of NPW to understand their impact on LI, human health, and building water systems. The outcome is a novel change in practice to reuse 25,141 m3/year RORW and 1136 m3/year FSPTW as makeup water for the A/C CW shortfall in winter. The results identify key considerations to be addressed by the target audience (building owners, landscape contractors, and facility managers) when reusing NPW to protect the environment against soil degradation—a major aspect of decarbonization.
