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.
A public–private partnership is a long-term arrangement between a government and private sector institutions. Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract. Public–private partnerships have been implemented in multiple countries and are primarily used for infrastructure projects. Although they are not compulsory, PPPs have been employed for building, equipping, operating and maintaining schools, hospitals, transport systems, and water and sewerage systems.
Water privatization is short for private sector participations in the provision of water services and sanitation. Water privatization has a variable history in which its popularity and favorability has fluctuated in the market and politics. One of the common forms of privatization is public–private partnerships (PPPs). PPPs allow for a mix between public and private ownership and/or management of water and sanitation sources and infrastructure. Privatization, as proponents argue, may not only increase efficiency and service quality but also increase fiscal benefits. There are different forms of regulation in place for current privatization systems.
The water industry provides drinking water and wastewater services to residential, commercial, and industrial sectors of the economy. Typically public utilities operate water supply networks. The water industry does not include manufacturers and suppliers of bottled water, which is part of the beverage production and belongs to the food sector.
United Nations Water (UN-Water) is an interagency mechanism that coordinates the efforts of United Nations entities and international organizations working on water and sanitation issues.
Water supply and sanitation (WSS) in the European Union (EU) is the responsibility of each member state, but in the 21st century union-wide policies have come into effect. Water resources are limited and supply and sanitation systems are under pressure from urbanisation and climate change. Indeed, the stakes are high as the European Environmental Agency found that one European out of ten already suffers a situation of water scarcity and the IEA measured the energy consumption of the water sector to be equivalent to 3,5% of the electricity consumption of the EU.
Access to at least basic water increased from 94% to 97% between 2000 and 2015; an increase in access to at least basic sanitation from 73% to 86% in the same period;
The water and sanitation sector in Peru has made important advances in the last two decades, including the increase of water coverage from 30% to 85% between 1980 and 2010. Sanitation coverage has also increased from 9% to 37% from 1985 to 2010 in rural areas. Advances have also been achieved concerning the disinfection of drinking water and in sewage treatment. Nevertheless, many challenges remain, such as:
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.
The Philippines' contemporary water supply system dates back to 1946, after the country declared independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge of the operation and administration of water supply and sanitation in the country.
Water supply and sanitation in Senegal is characterized by a relatively-high level of access compared to most of sub-Saharan Africa. A public–private partnership (PPP) has operated in Senegal since 1996, with Senegalaise des Eaux the private partner. SDE does not own the water system, but manages it on a 10-year lease from the Senegalese government. Between 1996 and 2014, water sales doubled to 131 million cubic meters per year; the number of household connections increased by 165 percent, to over 638,000. According to the World Bank, "The Senegal case is regarded as a model of public-private partnership in sub-Saharan Africa". A national sanitation company is in charge of sewerage, wastewater treatment and stormwater drainage, which is modeled on the national sanitation company of Tunisia and is unique in sub-Saharan Africa.
Tunisia has achieved the highest access rates to water supply and sanitation services among the Middle East and North Africa. As of 2011, access to safe drinking water became close to universal approaching 100% in urban areas and 90% in rural areas. Tunisia provides good quality drinking water throughout the year.
Water supply and sanitation in Jordan is characterized by severe water scarcity, which has been exacerbated by forced immigration as a result of the 1948 Arab–Israeli War, the Six-Day War in 1967, the Gulf War of 1990, the Iraq War of 2003 and the Syrian Civil War since 2011. Jordan is considered one of the ten most water scarce countries in the world. High population growth, the depletion of groundwater reserves and the impacts of climate change are likely to aggravate the situation in the future.
Drinking water supply and sanitation in Egypt directly impact the country's public health, industrial developments, and agriculture. Egypt's water and sanitation industry is characterized by both achievements and challenges. Among the achievements are an increase of piped water supply between 1998 and 2006 from 89% to 100% in urban areas and from 39% to 93% in rural areas despite rapid population growth; the elimination of open defecation in rural areas during the same period; and in general a relatively high level of investment in infrastructure. Access to an at least basic water source in Egypt is now practically universal with a rate of 98%. On the institutional side, the regulation and service provision have been separated to some extensions through the creation of a national Holding Company for Water and Wastewater in 2004, and of an economic regulator, the Egyptian Water Regulatory Agency (EWRA), in 2006. Despite these successes, many challenges remain. Only about one half of the population is connected to sanitary sewers. Because of this low sanitation coverage, about 50,000 children die each year because of diarrhea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Furthermore, poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues.
The 2030 Agenda for Sustainable Development, adopted by all United Nations (UN) members in 2015, created 17 world Sustainable Development Goals (SDGs). The aim of these global goals is "peace and prosperity for people and the planet" – while tackling climate change and working to preserve oceans and forests. The SDGs highlight the connections between the environmental, social and economic aspects of sustainable development. Sustainability is at the center of the SDGs, as the term sustainable development implies.
Right2Water is a campaign to commit the European Union and member states to implement the human right to water and sanitation.
Fecal sludge management (FSM) is the storage, collection, transport, treatment and safe end use or disposal of fecal sludge. Together, the collection, transport, treatment and end use of fecal sludge constitute the "value chain" or "service chain" of fecal sludge management. Fecal sludge is defined very broadly as what accumulates in onsite sanitation systems and specifically is not transported through a sewer. It is composed of human excreta, but also anything else that may go into an onsite containment technology, such as flushwater, cleansing materials, menstrual hygiene products, grey water, and solid waste. Fecal sludge that is removed from septic tanks is called septage.
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.
