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 have 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.
Guyana, meaning "land of many waters", is rich in water resources. Most of the population is concentrated in the coastal plain, much of which is below sea level and is protected by a series of sea walls. A series of shallow reservoirs inland of the coastal plain, called "water conservancies", store surface water primarily for irrigation needs. Key issues in the water and sanitation sector in Guyana are poor service quality, a low level of cost recovery and low levels of access.
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;
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.
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. Almost 30 million people lack access to an improved water source and more than 70 million of the country's 264 million population has no access to improved 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 in India has increased greatly from 1980 to present. Still, many people lack access to clean water, toilets, and sewage infrastructure. Various government programs at national, state, and community level have brought rapid improvements in sanitation and the drinking water supply. Some of these programs are ongoing.
Water supply and sanitation in China is undergoing a massive transition while facing numerous challenges such as rapid urbanization, increasing economic inequality, and the supply of water to rural areas. Water scarcity and pollution also impact access to water.
Water supply and sanitation in Rwanda is characterized by a clear government policy and significant donor support. In response to poor sustainability of rural water systems and poor service quality, in 2002 local government in the Northern Byumba Province contracted out service provision to the local private sector in a form of public–private partnership. Support for public-private partnerships became a government policy in 2004 and locally initiated public-private partnerships spread rapidly, covering 25% of rural water systems as of 2007.
The drinking water supply and sanitation sector in Ghana faces a number of challenges, including very limited access to sanitation, intermittent supply, high water losses and low water pressure. Since 1994, the sector has been gradually reformed through the creation of an autonomous regulatory agency, introduction of private sector participation, decentralization of the rural supply to 138 districts and increased community participation in the management of rural water systems.
With abundant water resources, Bangladesh faces various water contaminations mainly caused by pollutants, bacteria, and pesticides. Historically, water sources in Bangladesh came from surface water contaminated with bacteria. Drinking infected water resulted in infants and children suffering from acute gastrointestinal disease that led to a high mortality rate. According to UNICEF, 38.3% of Bangladeshis drink unsafe water from bacteria-contaminated sources. Bangladesh is facing an acute reliable drinking water scarcity. Bangladesh's surface and ground water are highly saline due to rising sea levels.
Drinking water supply and sanitation in Pakistan is characterized by some achievements and many challenges. Despite high population growth the country has increased the share of the population with access to an improved water source from 85% in 1990 to 92% in 2010, although this does not necessarily mean that the water from these sources is safe to drink. The share with access to improved sanitation increased from 27% to 48% during the same period, according to the Joint Monitoring Program for Water Supply and Sanitation. There has also been considerable innovation at the grass-root level, in particular concerning sanitation. The Orangi Pilot Project in Karachi and community-led total sanitation in rural areas are two examples of such innovation.
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.
Drinking water supply and sanitation in Egypt 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 extent 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.
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 management of Jamaica's freshwater resources is primarily the domain and responsibility of the National Water Commission (NWC). The duties of providing service and water infrastructure maintenance for rural communities across Jamaica are shared with the Parish Councils. Where possible efficiencies have been identified, the NWC has outsourced various operations to the private sector.
Water supply and sanitation in Kenya is characterised by low levels of access to water and sanitation, in particular in urban slums and in rural areas, as well as poor service quality in the form of intermittent water supply. Seasonal and regional water scarcity exacerbates the difficulty to improve water supply.
