  • Treatment wetlands in decentralised approaches for linking sanitation to energy and food security

    Treatment wetlands (TWs) are engineered systems that mimic the processes in natural wetlands with the purpose of treating contaminated water. Being a simple and robust technology, TWs are applied worldwide to treat various types of water. Besides treated water for reuse, TWs can be used in resources-oriented sanitation systems for recovering nutrients and carbon, as well as for growing biomass ...

  • Building Sustainable Sanitation Systems

    A low cost system of resource management such as composting toilets is helping to mitigate many of Haiti’s social and ecological challenges. The Caribbean Republic of Haiti — the poorest, most environmentally degraded country in the Western Hemisphere with a population of about 10 million — is a case study in forestry and soil fertility mismanagement. A colonial ...

  • Towards a research agenda for water, sanitation and antimicrobial resistance

    Clinically relevant antimicrobial resistant bacteria, genetic resistance elements, and antibiotic residues (so-called AMR) from human and animal waste are abundantly present in environmental samples. This presence could lead to human exposure to AMR. In 2015, the World Health Organization (WHO) developed a Global Action Plan for Antimicrobial Resistance with one of its strategic objectives ...

  • Alternative sanitation options for households and communities

    The resource-intensive wastewater collection and treatment systems found in many parts of the developed world are not feasible for meeting the sanitation[1] needs of the less developed regions still lacking or having poor sanitation.  Establishment and maintenance costs are high and large amounts of energy are ...

  • Ecological sanitation: An alternative route to sustainable livelihoods

    Most of the cities in Nepal,  except  Kathmandu,  the sewerage system  and onsite sanitation system are very poor due to improper management, less attention, and lack of political commitment of Gevernments of Nepal. The planned and safe disposal of human excreta is a must for preventing drinking water from pollution and conserving soil fertility. The conventional linear ...

  • Shipshape: sanitation inspections on cruise ships, 1990–2005, vessel sanitation program, centers for disease control and prevention

    In the course of a successful collaboration between the Centers for Disease Control and Prevention (CDC) and the cruise ship industry on reducing common-source outbreaks, CDC’s Vessel Sanitation Program (VSP) has expanded its training, education, and cruise ship inspection programs. The study reported here evaluated 15 years of ship sanitation inspection data from the National Center for ...

  • Safe greywater reuse to augment water supply and provide sanitation in semi-arid areas of rural India

    Water reuse is recognized as a tool to increase water supply in peri-urban areas of semi-arid and arid regions of the world. However, it is an option rarely explored for rural areas in developing countries, and has not been documented extensively in the scientific literature. This paper presents results from 6 greywater reuse systems which were built with the objective to augment water supply and ...

  • Feasibility of anaerobic membrane bioreactors (AnMBR) for onsite sanitation and resource recovery (nutrients, energy and water) in urban slums

    Slums are challenging locations for sanitation technologies. High population densities, a lack of water and electricity infrastructure, and space constraints combine to ensure that many traditional waste treatment technologies fail when implemented in this context. This paper proposes the use of anaerobic membrane bioreactors (AnMBRs) for slum sanitation. AnMBRs allow for localized water ...

  • Profile of Ozone/Bromine Sanitation Systems for City of Tucson Municipal Pools

    Due to the inherent risks associated with the use of chlorine gas as a sanitizer for the City of Tucson’s twenty-six municipal swimming pool sites, I found myself in search of an alternative water sanitation method. The challenge was clear; find a system that would be safer to manage than gas chlorine, yet yield the same favorable sanitation and water quality results. Since all the sites ...

  • The potential of System Dynamics Modelling in assessing global water-energy-food security issues

    Water security and interconnected issues are gaining awareness in various international arenas, highlighted by publications investigating aspects of water budgets, availability, scarcity and trade [1-3]. Many of the world's freshwater sources are over-exploited [4-5]. This situation is likely to become exacerbated as population increases (to c. 9-11 billion by 2050; [6]), as per-capita water ...

  • Water grabbing fact sheet for World Water Week

    Ground and surface waters are under increasing stress around the world. The goal to ensure sustainable food and water security is being put further at risk from large-scale land acquisitions targeting lands with water for irrigation. In parts of Africa, Latin America and Southeast Asia, powerful interests are acquiring lands either with associated water resources or with the promise of water ...

  • Water-based diseases

    Waterborne diseases are caused by pathogenic microorganisms which are directly transmitted when contaminated fresh water is consumed. Contaminated fresh water, used in the preparation of food, can be the source of foodborne disease through consumption of the same microorganisms. According to the World Health Organization, diarrheal disease accounts for an estimated 4.1% of the total DALY ...

  • Microdisk arrays for peroxide analysis in water

    Hydrogen peroxide (H2O2) and peracetic acid (PAA) are used as bleaching and disinfecting agents. The bactericidal and al-gaecidal properties of peroxides [1] and the advantage that they decompose into harmless residues, make them suitable for a broad range of applications, including oxidizing and bleaching agents in laundry formulations, sanitization of food equipment, paper bleaching and medical ...


  • Ensuring Water Quality in Africa

    Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water. This year completes the UN “Water for Life” international decade for ...

    The Stockholm World Water Week’s focus on “Water for Development” comes at an opportune time. Water as a sector in world affairs is reaching a tipping point. Over the next two decades and more, the global push for food and energy security and for sustaining urbanization will place new and increasing demands on the water sector. Ours is a world of ‘thirsty ...

  • The role of process water in pathogen reduction

    The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...
