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.
Water supply and sanitation in Mexico is characterized by achievements and challenges. Among the achievements is a significant increase in access to piped water supply in urban areas as well as in rural areas between 1990 and 2010. Additionally, a strong nationwide increase in access to improved sanitation was observed in the same period. Other achievements include the existence of a functioning national system to finance water and sanitation infrastructure with a National Water Commission as its apex institution; and the existence of a few well-performing utilities such as Aguas y Drenaje de Monterrey.
Drinking water supply and sanitation coverage in Honduras has increased significantly in the last decades. However, the sector is still characterized by poor service quality and poor efficiency in many places. Coverage gaps still remain, particularly in rural areas.
Water supply and sanitation in Indonesia is characterized by poor levels of access and service quality. More than 16 million people lack access to an at least basic water source and almost 33 million of the country's 275 million population has no access to at least basic sanitation. Only about 2% of people have access to sewerage in urban areas; this is one of the lowest in the world among middle-income countries. Water pollution is widespread on Bali and Java. Women in Jakarta report spending US$11 per month on boiling water, implying a significant burden for the poor.
The water supply and sanitation sector in Ghana is a sector that is in charge of the supply of healthy water and also improves the sanitation of water bodies in the country.
Bangladesh is faced with multiple water quality and quantity problems along with regular natural disasters, such as cyclones and floods. Available options for providing safe drinking water include tubewells, traditionally dug wells, treatment of surface water, desalination of groundwater with high salinity levels and rainwater harvesting.
Water resources management (WRM) in Honduras is a work in progress and at times has advanced; however, unstable investment and political climates, strong weather phenomena, poverty, lack of adequate capacity, and deficient infrastructures have and will continue to challenge developments to water resource management. The State of Honduras is working on a new General Water Law to replace the 1927 Law on Using National Waters and designed to regulate water use and management. The new water law will also create a Water Authority, and the National Council of Water Resources which will serve as an advising and consultative body.
Microcredit for water supply and sanitation is the application of microcredit to provide loans to small enterprises and households in order to increase access to an improved water source and sanitation in developing countries. While most investments in water supply and sanitation infrastructure are financed by the public sector, investment levels have been insufficient to achieve universal access. Commercial credit to public utilities was limited by low tariffs and insufficient cost-recovery. Microcredits are a complementary or alternative approach to allow the poor to gain access to water supply and sanitation in the aforementioned regions.
Water resources management in Nicaragua is carried out by the National water utility and regulated by the Nicaraguan Institute of water. Nicaragua has ample water supplies in rivers, groundwater, lagoons, and significant rainfall. Distribution of rainfall is uneven though with more rain falling on an annual basis in the Caribbean lowlands and much lower amounts falling in the inland areas. Significant water resources management challenges include contaminated surface water from untreated domestic and industrial wastewater, and poor overall management of the available water resources.
Water supply and sanitation in Tanzania is characterised by: decreasing access to at least basic water sources in the 2000s, steady access to some form of sanitation, intermittent water supply and generally low quality of service. Many utilities are barely able to cover their operation and maintenance costs through revenues due to low tariffs and poor efficiency. There are significant regional differences and the best performing utilities are Arusha and Tanga.
The Global Water Security & Sanitation Partnership (GWSP), formerly the Water and Sanitation Program, is a trust fund administered by the World Bank geared at improving the accessibility and infrastructure of water and sanitation for underdeveloped countries. GWSP works in more than 25 countries through regional offices in Africa, East and South Asia, Latin America, the Caribbean, and an office in Washington, D.C. Heath P. Tarbert is the Acting Executive Director for the United States. The GWSP is best known for its work providing technical assistance, building partnerships and capacity building. GWSP focuses on both regulatory and structural changes and also behavior change projects, such as a scaling up handwashing project and scaling up sanitation project. Another key aspect of GWSP's work is sharing knowledge and best practices through multiple channels. The GWSP has determined five main focus areas: Sustainability, inclusion, institutions, financing, and resilience.
Although access to water supply and sanitation in sub-Saharan Africa has been steadily improving over the last two decades, the region still lags behind all other developing regions. Access to improved water supply had increased from 49% in 1990 to 68% in 2015, while access to improved sanitation had only risen from 28% to 31% in that same period. Sub-Saharan Africa did not meet the Millennium Development Goals of halving the share of the population without access to safe drinking water and sanitation between 1990 and 2015. There still exists large disparities among sub-Saharan African countries, and between the urban and rural areas.
The main causes of water scarcity in Africa are physical and economic water scarcity, rapid population growth, and the effects of climate change on the water cycle. Water scarcity is the lack of fresh water resources to meet the standard water demand. The rainfall in sub-Saharan Africa is highly seasonal and unevenly distributed, leading to frequent floods and droughts.
Water issues in developing countries include scarcity of drinking water, poor infrastructure for water and sanitation access, water pollution, and low levels of water security. Over one billion people in developing countries have inadequate access to clean water. The main barriers to addressing water problems in developing nations include poverty, costs of infrastructure, and poor governance. The effects of climate change on the water cycle can make these problems worse.
Responsibility of water supply in Nigeria is shared between three (3) levels of government – federal, state and local. The federal government is in charge of water resources management; state governments have the primary responsibility for urban water supply; and local governments together with communities are responsible for rural water supply. The responsibility for sanitation is not clearly defined.
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.
Although the Democratic Republic of the Congo (DRC) has Africa's largest freshwater resources, it is suffering from an acute drinking water supply crisis. The DRC has one of the lowest rates of access to clean drinking water in Sub-Saharan Africa and the world. Only 46 percent of the population had access to an improved drinking water source in 2012. Furthermore, the sanitation coverage was estimated at only 31 percent in 2012. Up to date and accurate information on water supply and sanitation services in the DRC is scarce. As a result of inadequate water supply and sanitation services, many inhabitants are suffering from waterborne diseases, including diarrhoea, typhoid, and cholera.
Laos is a nation with plentiful surface water and broad rivers, but outside of cities, water sanitation and accessibility infrastructure is sparse. Few improvements have been made since the end of the Laotian Civil War in 1975, especially compared to peer nations such as Thailand. By 2015, 76% of Laotians nationwide were estimated to have access to “improved” water, while 71% were estimated to have access to “improved” sanitation.
Lesotho is a mountainous and fairly 'water-rich country', but suffers from a lack of clean drinking water due to inadequate sanitation. In recent decades, with the construction of dams for the Lesotho Highlands Water Project (LHWP), Lesotho has become the main provider of water to parts of northern South Africa. Despite the economic and infrastructure development occasioned by the LHWP, waterborne diseases are common in the country and the infant mortality rate from them is high. In 2017, a project to improve the rural water supply in the Lesotho Lowlands was funded by the Global Environment Facility and the African Development Bank, and is ongoing.
