This research paper examines the use of interbasin water and wastewater transfers in Nogales, Sonora, to manage water scarcity driven by population growth, climate warming, and institutional asymmetries. It specifically analyzes the export of wastewater to the US and the Alisos basin, concluding that these strategies exacerbate water scarcity in Nogales and cause negative health, environmental, and livelihood impacts in the source basin.

This research paper reviews greenhouse gas (GHG) emissions across the sanitation and wastewater management chain to improve climate change considerations in sanitation planning, identifying significant data and methodological gaps in current literature.

This research paper assesses the environmental and societal impacts of three urine concentration technologies—alkaline dehydration, nitrification-distillation, and ion-exchange with struvite precipitation—within a planned residential area in Malmö, Sweden, to provide guidance for scaling up nutrient recovery for a circular economy.

This briefing examines the 25-year history and impact of the Global Programme of Action (GPA) for the Protection of the Marine Environment from Land-based Activities, detailing its role in coordinating international efforts to combat marine pollution from terrestrial sources.

This 2019 industry brief by GreenCape examines the challenges and options for managing brine—highly concentrated saline wastewater—produced when companies in Cape Town treat saline groundwater using technologies like reverse osmosis (RO). The document outlines direct discharge and treatment methods, noting that high costs and strict regulatory requirements often make these solutions financially unviable.

This briefing by the International Institute for Sustainable Development outlines strategies to enhance the climate resilience of water supply and sanitation systems in Alberta's urban centres, specifically Calgary and Edmonton. It advocates for a transition from highly centralized infrastructure toward a 'multi-barrier' approach incorporating redundancy, decentralization, and low-impact development (LID) to mitigate risks from extreme weather, such as droughts and floods.

The 2014 Green Drop Progress Report, published by GreenCape, provides a national overview of wastewater treatment performance in South Africa. It utilizes the Progress Assessment Tool (PAT) to track the Cumulative Risk Rating (CRR) of municipal, public, and private wastewater treatment plants, highlighting a general trend of increasing risk across the sector between 2013 and 2014.

This 2006 report by the Stockholm Environment Institute examines urine diversion as a sustainable sanitation alternative to help meet the Millennium Development Goals (MDGs). It details the technical, organizational, and economic aspects of separating urine from faeces to enable nutrient recycling in agriculture, drawing heavily on Swedish municipal experiences and international case studies from West Africa, China, and El Salvador.

This document is a draft reply from the South African Minister of Water and Environmental Affairs to a National Assembly question regarding challenges with water source protection policy compliance, the department's mitigation plans, the impacts of non-compliance, and enforcement measures.
