Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few.
World Toilet Day (WTD) is an official United Nations international observance day on 19 November to inspire action to tackle the global sanitation crisis. Worldwide, 4.2 billion people live without "safely managed sanitation" and around 673 million people practice open defecation. Sustainable Development Goal 6 aims to "Ensure availability and sustainable management of water and sanitation for all". In particular, target 6.2 is to "End open defecation and provide access to sanitation and hygiene". When the Sustainable Development Goals Report 2020 was published, United Nations Secretary-General António Guterres said, "Today, Sustainable Development Goal 6 is badly off track" and it "is hindering progress on the 2030 Agenda, the realization of human rights and the achievement of peace and security around the world".
World Water Day is an annual United Nations (UN) observance day held on the 22nd of March that highlights the importance of fresh water. The day is used to advocate for the sustainable management of freshwater resources. The theme of each year focuses on topics relevant to clean water, sanitation and hygiene (WASH), which is in line with the targets of Sustainable Development Goal 6. The UN World Water Development Report (WWDR) is released each year around World Water Day.
Ecological sanitation, commonly abbreviated as ecosan, is an approach to sanitation provision which aims to safely reuse excreta in agriculture. It is an approach, rather than a technology or a device which is characterized by a desire to "close the loop", mainly for the nutrients and organic matter between sanitation and agriculture in a safe manner. One of the aims is to minimise the use of non-renewable resources. When properly designed and operated, ecosan systems provide a hygienically safe system to convert human excreta into nutrients to be returned to the soil, and water to be returned to the land. Ecosan is also called resource-oriented sanitation.
The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, often simply shortened to GIZ, is the main German development agency. It is headquartered in Bonn and Eschborn and provides services in the field of international development cooperation and international education work. The organization's self-declared goal is to deliver effective solutions that offer people better prospects and sustainably improve their living conditions.
Stockholm Environment Institute, or SEI, is a non-profit, independent research and policy institute specialising in sustainable development and environmental issues, with seven affiliate offices around the world. SEI works on climate change, energy systems, water resources, air quality, land-use, sanitation, food security, and trade issues with the aim to shift policy and practice towards sustainability.
Sustainable sanitation is a sanitation system designed to meet certain criteria and to work well over the long-term. Sustainable sanitation systems consider the entire "sanitation value chain", from the experience of the user, excreta and wastewater collection methods, transportation or conveyance of waste, treatment, and reuse or disposal. The Sustainable Sanitation Alliance (SuSanA) includes five features in its definition of "sustainable sanitation": Systems need to be economically and socially acceptable, technically and institutionally appropriate and protect the environment and natural resources.
Urine diversion, also called urine separation or source separation, refers to the separate collection of human urine and feces at the point of their production, i.e. at the toilet or urinal. Separation of urine from feces allows human waste to be treated separately and used as a potential resource. Applications are typically found where connection to a sewer-based sanitation system is not available or areas where water supplies are limited.
A dry toilet is a toilet which, unlike a flush toilet, does not use flush water. Dry toilets do not use water to move excreta along or block odors. They do not produce sewage, and are not connected to a sewer system or septic tank. Instead, excreta falls through a drop hole.
WASH is a sector in development cooperation or within local governments that provides water, sanitation, and hygiene services to people. The main purposes of providing access to WASH services include achieving public health gains, implementing the human right to water and sanitation, reducing the burden of collecting drinking water for women, and improving education and health outcomes at schools and health facilities. Access to WASH services is also an important component of water security. Universal, affordable, and sustainable access to WASH is a key issue within international development and is the focus of the first two targets of Sustainable Development Goal 6. Targets 6.1 and 6.2 aim for equitable and accessible water and sanitation for all. In 2017, it was estimated that 2.3 billion people live without basic sanitation facilities, and 844 million people live without access to safe and clean drinking water. The acronym WASH is used widely by non-governmental organizations and aid agencies in developing countries.
The Water Supply and Sanitation Collaborative Council (WSSCC) was a United Nations-hosted organization contributing to Sustainable Development Goal 6, Target 6.2 on sanitation and hygiene. It was established in 1990 and closed at the end of 2020. WSSCC advocated for improved sanitation and hygiene, with a focus on the needs of women, girls and people in vulnerable situations.
Water supply and sanitation in Zimbabwe is defined by many small scale successful programs but also by a general lack of improved water and sanitation systems for the majority of Zimbabwe. Water supply and sanitation in Zimbabwe faces significant challenges, marked by both successful localized efforts and widespread deficiencies in infrastructure. According to the 2019 Multiple Indicator Cluster Surveys (MICS), conducted by UNICEF, disparities persist in access to clean drinking water and sanitation facilities. While overall access to improved drinking water sources increased to 77.1% in 2019 from 76.1% in 2014, significant gaps remain between urban and rural areas, as well as within urban centers. For instance, 97.3% of urban households have access to improved water sources compared to only 67.9% of rural households. Similarly, disparities exist across regions, with Harare boasting the highest access at 96.6%, contrasting sharply with 64.8% in Matabeleland South. Additionally, approximately 67.8% of households have access to improved, non-shared sanitation facilities, indicating ongoing challenges in this domain. Urban areas, in particular, grapple with chronic water shortages amid rising consumption demands. There are many factors which continue to determine the nature, for the foreseeable future, of water supply and sanitation in Zimbabwe. Three major factors are the severely depressed state of the Zimbabwean economy, the willingness of foreign aid organizations to build and finance infrastructure projects, and the political stability of the Zimbabwean state.
Menstrual Hygiene Day is an annual awareness day on May 28 to highlight the importance of good menstrual hygiene management (MHM) at a global level. It was initiated by the German-based NGO WASH United in 2013 and observed for the first time in 2014.
IRC is an international think tank that works with governments, NGOs, entrepreneurs and people around the world to find long-term solutions to the global crisis in water, sanitation and hygiene services. Founded in 1968, IRC is a non-profit organisation registered since 1980 as a Foundation under Dutch Law. It has its headquarters in The Hague, the Netherlands with country offices in Burkina Faso, Ethiopia, Ghana, Mali and Uganda. In 2021, IRC had 130 staff members and 30 associates, and recorded a turnover of €8.7 million.
Sustainable Development Goal 6 declares the importance of achieving "clean water and sanitation for all". It is one of the 17 Sustainable Development Goals established by the United Nations General Assembly to succeed the former Millennium Development Goals (MDGs). According to the United Nations, the overall goal is to: "Ensure availability and sustainable management of water and sanitation for all." The goal has eight targets to be achieved by 2030 covering the main areas of water supply and sanitation and sustainable water resource management. Progress toward the targets will be measured by using eleven indicators.
A shit flow diagram is a high level technical drawing used to display how excreta moves through a location, and functions as a tool to identify where improvements are needed. The diagram has a particular focus on treatment of the waste, and its final disposal or use. SFDs are most often used in developing countries.
The Rural Water Supply Network (RWSN) is a global, multi-stakeholder network focused on achieving universal access to safe, affordable drinking water for all rural people worldwide. Established in 1992 as the Handpump Technology Network (HTN), the organization originally concentrated on the development and maintenance of handpump technologies. Over time, it expanded its scope to address broader rural water supply issues, and in 2004, it was rebranded as RWSN. The network has no legal structure and instead is a loose collaboration.
The African Ministers' Council on Water (AMCOW) (French: Conseil des Ministres Africains Chargés de L'eau), is considered by the African Union as the support mechanism for its Specialised Technical Committee (STC) to drive achievement in the water and sanitation sectors. It is a regional development network of 55 African countries that advances socioeconomic development and the abolition of poverty through effective cooperation, management of water supply services, and provision of the continent's water resources to its members.
