Despite many years of concerted efforts and achievements in expanding coverage and improving service sustainability, many issues remain to be addressed in the water and sanitation sector. Key issues include: (i) a low level of coverage for both water and sanitation, in particular in rural areas; (ii) a low level of cost recovery, despite a legal obligation for tariffs to recover costs; and (iii) an institutional framework that is only partially effective.
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Water is the name of the liquid state of H2O at standard ambient temperature and pressure. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.
Sanitation refers to public health conditions related to clean drinking water and adequate 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 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, trachoma, to name just a few.
While coverage levels in urban areas are high using a broad definition of services, the coverage with higher levels of services (house taps and sewers) remains low compared to demand and to other countries in the region.
An urban area or urban agglomeration is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment.

The United Nations Children's Fund (UNICEF), originally known as the United Nations International Children's Emergency Fund, was created by the United Nations General Assembly on 11 December 1946, to provide emergency food and healthcare to children and mothers in countries that had been devastated by World War II. The Polish physician Ludwik Rajchman is widely regarded as the founder of UNICEF and served as its first chairman from 1946 to 1950, when he had to flee the United States in the wake of McCarthyism. Rajchman is to this day the only person that served as UNICEF's Chairman for longer than 2 years. On Rajchman's suggestion, the American Maurice Pate was appointed its first executive director, serving from 1947 until his death in 1965. In 1950, UNICEF's mandate was extended to address the long-term needs of children and women in developing countries everywhere. In 1953 it became a permanent part of the United Nations System, and the words "international" and "emergency" were dropped from the organization's name, though it retained the original acronym, "UNICEF".
In April 2007 a seminar organized by the Center of Multidisciplinary Entrepreneurial Training (CAEM)-TECMA S.A. and financed by the IDB concluded that the Juntas need to improve their management and improve collection of outstanding bills in order to avoid institutional collapse. Otherwise a “domino effect” could occur and jeopardize the financial stability of SENASA as well as the country's commitments to the World Bank. [1]
The Inter-American Development Bank is the largest source of development financing for Latin America and the Caribbean. Established in 1959, the IDB supports Latin American and Caribbean economic development, social development and regional integration by lending to governments and government agencies, including State corporations.
Responsibility for policy formulation is nominally vested in the Ministry of Public Works and Communications and regulation is entrusted to an autonomous entity, the Regulatory Agency for Sanitation (ERSSAN). The institutional framework is codified in Law 1614/00 of 2000 establishing a regulatory and tariff framework for the sector. The law, which created ERSSAN, was drafted with the expectation that private sector participation in the sector would substantially increase, which did not occur.
In practice, the Ministry of Public Works and Communications has not developed sector policies, leaving a vacuum in this important area. The regulatory agency, created for the purpose of regulating prospective private enterprises, has been ineffective at regulating the national public enterprise ESSAP. SENASA also faces many challenges, since it does not have sufficient capacity to provide adequate support to the ever-increasing number of Juntas.
Responsibility for water and sanitation service provision in Paraguay in urban areas rests primarily with a national public enterprise, and with more than 1,621 community-managed water associations (Juntas de Saneamiento) in small cities and in rural areas.
Paraguay, officially the Republic of Paraguay, is a country of South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. Although it is one of only two landlocked countries in South America, the country has coasts, beaches and ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean through the Paraná-Paraguay Waterway. Due to its central location in South America, it is sometimes referred to as Corazón de Sudamérica.
The national enterprise, the Empresa de Servicios Sanitarios de Paraguay (ESSAP), is responsible for serving communities with populations of more than 10,000 inhabitants. In rural communities and small towns with less than 10,000 inhabitants water associations provide services, while technical assistance and financing are provided by the National Environmental Sanitation Service (SENASA).
The Juntas are grouped in 10 associations which supply water to more than half of country's population [2] The first Juntas were created with the assistance of the World Bank's first rural water and sanitation loan to Paraguay in 1977, fostering a successful long-term partnership that endures until today.
An interesting phenomenon in Paraguay is the emergence of independent private suppliers, called “aguateros”, since the 1970s. Their efforts account for a significant share of the expansion of urban water coverage in the area of the capital. Aguateros are private, informal service providers who operate small-scale systems with up to 3,000 connections. An estimated 500 private suppliers serve some total of about 500,000 people.
Urban utility tariffs are set below cost recovery levels and are adjusted infrequently, leading to substantial operating losses by the national water and sanitation enterprise. This makes it impossible to finance the investments necessary to further expand coverage and to improve service quality.
Tariffs by Aguateros fully recover costs and compare favorably with tariffs charged by the public sector. These tariffs are not regulated, but to some extent controlled by competition between aguateros serving neighboring areas.
Unlike in many other countries, local Juntas are well organized and do not only recover operating and maintenance costs, but also expand their systems using their own resources and repay a portion of capital costs to the national treasury.
According to data collected by the Pan-American Health Organization based on multi-purpose household surveys, the share of water expenditures in household expenditures in urban areas of Paraguay was the lowest among 10 countries in Latin America and the Caribbean in the late 1990s. The share was on average 1.4% and 1.7% for urban households in the poorest income decile, showing an unusually low difference between the average and poor households. [3] These shares are actually the same or even higher in rural areas, reflecting the unusual high levels of cost recovery in rural areas in Paraguay. Rural households spend on average 1.2% on water, and households in the poorest decile in rural areas spend 2.3% on water. Therefore, despite high levels of cost recovery, tariffs apparently remain affordable.
As mentioned above, the World Bank’s relationship with the Government of Paraguay and the SENASA on rural water systems goes back for about 30 years. It spans three successfully completed rural water projects: the First, Second, and Third Rural Water Supply and Sanitation Projects (approved on December 13, 1977, June 16, 1981, and September 10, 1992, respectively). As a result, the Bank is one of the institutions most trusted by the Government to assist it in this sector. From 1997 to 2007 the Bank supported the US$ 55.7 million Fourth Rural Water Supply and Sanitation Project (approved on August 28, 1997), which aimed at increasing water supply and sanitation coverage in rural areas. A secondary development objective was to modify SENASA’s role in the sector from an implementer of projects to an efficiently managed promoter of activities.
The World Bank has also supported a pilot project to expand services in small towns by providing subsidies on a competitive basis, which involve “aguateros” as service providers. This experience is summarized in the note entitled Output-Based Aid in Water – Lessons in Implementation from a pilot in Paraguay. [4]
On April 14, 2009, the World Bank approved a $64 million loan for the Paraguay Water and Sanitation Sector Modernization Project. The objective of the project is to increase the efficiency, coverage, and sustainability of water supply and sanitation services in Paraguay by (a) improving the governance of the sector, (b) improving water services and increasing access to sewerage services in the Asunción metropolitan area, and (c) increasing access to sustainable water and sanitation services in rural areas.
In 2001 the IDB approved a US$12m loan to support a Small Community Water Supply Sanitation Project executed by SENASA. Until 2007 more than US$7m had been disbursed.
Water supply and sanitation in Latin America is characterized by insufficient access and in many cases by poor service quality, with detrimental impacts on public health. Water and sanitation services are provided by a vast array of mostly local service providers under an often fragmented policy and regulatory framework. Financing of water and sanitation remains a serious challenge.

Water supply and sanitation in Colombia has been improved in many ways over the past decades. Between 1990 and 2010, access to improved sanitation increased from 67% to 82%, but access to improved water source's increased only slightly from 89% to 94%. In particular, coverage in rural areas lags behind. Furthermore, despite improvements, the quality of water and sanitation services remains inadequate. For example, only 73% of those receiving public services receive water of potable quality and in 2006 only 25% of the wastewater generated in the country underwent any kind of treatment.
Access to drinking water and sanitation in El Salvador has been increased significantly. A 2015 conducted study by the University of North Carolina called El Salvador the country that has achieved the greatest progress in the world in terms of increased access to water supply and sanitation and the reduction of inequity in access between urban and rural areas. However, water resources are heavily polluted and the great majority of wastewater is discharged without any treatment into the environment. Institutionally a single public institution is both de facto in charge of setting sector policy and of being the main service provider. Attempts at reforming and modernizing the sector through new laws have not borne fruit over the past 20 years.
Water supply and sanitation in Chile is characterized by high levels of access and good service quality. Compared to most other countries, Chile's water and sanitation sector distinguishes itself by the fact that almost all urban water companies are privately owned or operated. The sector also prides itself of having a modern and effective regulatory framework, including an innovative subsidy to water demand by the poor. One weakness of the sector is the relatively high water losses.
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.
Drinking water and sanitation in Nicaragua are provided by a national public utility in urban areas and water committees in rural areas. Despite relatively high levels of investment, access to drinking water in urban areas has barely kept up with population growth, access to urban sanitation has actually declined and service quality remains poor. However, a substantial increase in access to water supply and sanitation has been reached in rural areas.
Drinking water supply and sanitation in Argentina is characterized by relatively low tariffs, mostly reasonable service quality, low levels of metering and high levels of consumption for those with access to services. At the same time, according to the WHO, 21% of the total population remains without access to house connections and 52% of the urban population do not have access to sewerage. The responsibility for operating and maintaining water and sanitation services rests with 19 provincial water and sewer companies, more than 100 municipalities and more than 950 cooperatives, the latter operating primarily in small towns. Among the largest water and sewer companies are Agua y Saneamientos Argentinos (AYSA) and Aguas Bonarenses S.A. (ABSA), both operating in Greater Buenos Aires, Aguas Provinciales de Santa Fe, and Aguas Cordobesas SA, all of them now publicly owned. In 2008 there were still a few private concessions, such as Aguas de Salta SA, which is majority-owned by Argentine investors, and Obras Sanitarias de Mendoza (OSM).
Bolivia's drinking water and sanitation coverage has greatly improved since 1990 due to a considerable increase in sectoral investment. However, the country continues to suffer from what happens to be the continent's lowest coverage levels and from low quality of services. Political and institutional instability have contributed to the weakening of the sector's institutions at the national and local levels. Two concessions to foreign private companies in two of the three largest cities—Cochabamba and La Paz/El Alto—were prematurely ended in 2000 and 2006 respectively. The country's second largest city, Santa Cruz de la Sierra, relatively successfully manages its own water and sanitation system by way of cooperatives. The government of Evo Morales intends to strengthen citizen participation within the sector. Increasing coverage requires a substantial increase of investment financing.

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:
Costa Rica has made significant progress in the past decade in expanding access to water supply and sanitation, but the sector faces key challenges in low sanitation connections, poor service quality, and low cost recovery.
The Dominican Republic has achieved impressive increases in access to water supply and sanitation over the past two decades. However, the quality of water supply and sanitation services remains poor, despite the country's high economic growth during the 1990s.
Rapid improvements are being made in augmenting drinking water supply and sanitation in India, due to concerted efforts by the various levels of government and communities at improving coverage. The level of investment in water and sanitation, albeit low by international standards, has increased in size during the 2000s. For example, in 1980 rural sanitation coverage was estimated at 1% and reached 95% in 2018. Also, the share of Indians with access to improved sources of water has increased significantly from 72% in 1990 to 88% in 2008. At the same time, local government institutions in charge of operating and maintaining the infrastructure are seen as weak and lack the financial resources to carry out their functions. In addition, only two Indian cities have continuous water supply and according to an estimate from 2018 about 8% of Indians still lack access to improved sanitation facilities. A study by Water Aid estimated as many as 10 million Indians, or 5 percent of Indians living in urban areas, live without adequate sanitation. India comes in first place globally for having the greatest number of urban-dwelling inhabitants living without sanitation. India tops the urban sanitation crisis, has the largest amount of urban dwellers without sanitation, and the most open defecators(urban) with over 5 million people.
The drinking water supply and sanitation sector in Guatemala is characterized by low and inconsistent service coverage, especially in rural areas; unclear allocation of management responsibilities; and little or no regulation and monitoring of service provision.
Water supply and sanitation in Panama is characterized by relatively high levels of access compared to other Latin American countries. However, challenges remain, especially in rural areas.
Water supply and sanitation in Zambia is characterized by achievements and challenges. Among the achievements are the creation of regional commercial utilities for urban areas to replace fragmented service provision by local governments; the establishment of a regulatory agency that has substantially improved the availability of information on service provision in urban areas; the establishment of a devolution trust fund to focus donor support on poor peri-urban areas; and an increase in the access to water supply in rural areas.
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.
Although access to water supply and sanitation in Sub-Saharan Africa has been steadily improving over the past two decades, the region still lags behind all other developing regions. Access to improved water supply has increased from 49% in 1990 to 60% in 2008, while access to improved sanitation has only risen from 28% to 31%. Sub-Saharan Africa is unlikely to 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 are, however, large disparities among Sub-Saharan countries, and between the urban and rural areas.
Water supply and sanitation in Vietnam is characterized by challenges and achievements. Among the achievements is a substantial increase in access to water supply and sanitation between 1990 and 2010, nearly universal metering, and increased investment in wastewater treatment since 2007. Among the challenges are continued widespread water pollution, poor service quality, low access to improved sanitation in rural areas, poor sustainability of rural water systems, insufficient cost recovery for urban sanitation, and the declining availability of foreign grant and soft loan funding as the Vietnamese economy grows and donors shift to loan financing. The government also promotes increased cost recovery through tariff revenues and has created autonomous water utilities at the provincial level, but the policy has had mixed success as tariff levels remain low and some utilities have engaged in activities outside their mandate.
