Health risks from non-potable use of recycled water in buildings. Part 2 - Greywater
Summary
This review describes the physical, chemical, and microbiological quality of greywater and examines the health risks associated with its non-potable reuse in buildings through ingestion, inhalation, and dermal contact exposure pathways. The authors recommend combining treated water quality standards with technology performance requirements (expressed as log reductions of reference pathogens) and safe-use behavioral guidance for public health protection.

Greywater Reuse: Contaminant Profile, Health Implications, and Sustainable Solutions
This review examines the safety of reusing household greywater (from laundry, bathing, and dishes) and finds it contains a wide range of contaminants including microplastics, pharmaceuticals, and pathogens. The authors highlight that microplastics from synthetic clothing fibers are especially common in laundry greywater. Reusing this water for irrigation or other purposes without proper treatment could introduce microplastics and other harmful substances into soil and food crops.
Evaluation of Potential Health Risks from Microplastics in Drinking Water
This review assesses the potential human health risks of microplastics in drinking water, noting that while microplastics are widely detected, the health effects at typical exposure levels remain poorly understood. The authors call for improved risk assessment methods and drinking water monitoring standards.
Benefits and limitations of recycled water systems in the building sector: a review
Researchers reviewed the benefits and challenges of recycling greywater (lightly used household water) in buildings, finding it can improve concrete workability by 12–14% and reduce strain on freshwater supplies. While promising for sustainability, widespread adoption is held back by dual-pipe infrastructure costs, water quality concerns, and gaps in regulation.
Health effects associated with wastewater treatment, reuse, and disposal
This annual review summarizes 2018 research on health effects associated with wastewater treatment, water reuse, and sewage disposal, covering microbial risks, chemical contaminants, and emerging pollutants including microplastics. The review highlights ongoing concerns about how wastewater management practices influence both environmental quality and public health.
The role of grey water footprint in urban wastewater management: from pollution to reuse
This study evaluated grey water footprint as a qualitative indicator of wastewater impact using eight years of real data from a municipal treatment plant and its receiving water body, demonstrating its utility for tracking wastewater management effectiveness over time.
