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.
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.
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 Yemen is characterized by many challenges as well as some achievements. A key challenge is severe water scarcity, especially in the Highlands, prompting The Times of London to write "Yemen could become the first nation to run out of water". A second key challenge is a high level of poverty, making it very difficult to recover the costs of service provision. Access to water supply sanitation in Yemen is as low or even lower than that in many sub-Saharan African countries. Yemen is both the poorest country and the most water-scarce country in the Arab world. Third, the capacity of sector institutions to plan, build, operate and maintain infrastructure remains limited. Last but not least the security situation makes it even more difficult to improve or even maintain existing levels of service.
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.
In 1993, the country's groundwater, the source of drinking water for 97% of the rural population and a significant share of the urban population, was contaminated with arsenic. However, in 2004, 98.5% of the population already has access to an improved water source, a very high level for a low-income country. This has been achieved through the construction of hand pumps with the support of external donors.
The Ugandan water supply and sanitation sector made substantial progress in urban areas from the mid-1990s until at least 2006, with substantial increases in coverage as well as in operational and commercial performance. Sector reforms from 1998 to 2003 included the commercialization and modernization of the National Water and Sewerage Corporation (NWSC) operating in cities and larger towns, as well as decentralization and private sector participation in small towns.
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.
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 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.
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.
Water supply and sanitation in Burkina Faso are characterized by high access to water supply in urban areas, while access to an at least basic water sources in rural areas – where three quarters of the population live – remains relatively low. An estimated one third of water facilities in rural areas are out of service because of a lack of maintenance. Access to at least basic sanitation lags significantly behind access to water supply.
Water supply and sanitation in Turkey is characterized by achievements and challenges. Over the past decades access to drinking water has become almost universal and access to adequate sanitation has also increased substantially. Autonomous utilities have been created in the 16 metropolitan cities of Turkey and cost recovery has been increased, thus providing the basis for the sustainability of service provision. Intermittent supply, which was common in many cities, has become less frequent. In 2004, 61% of the wastewater collected through sewers was being treated. In 2020 77% of water was used by agriculture, 10% by households and the rest by industry.
The Phnom Penh Water Supply Authority (PPWSA) is the municipal water utility that serves Cambodia's capital Phnom Penh and surrounding areas.
Water supply in Sierra Leone is characterized by limited access to safe drinking water. Despite efforts by the government and numerous non-governmental organizations, access has not much improved since the end of the Sierra Leone Civil War in 2002, stagnating at about 50% and even declining in rural areas. In the capital Freetown, taps often run dry. It is hoped that a new dam in Orugu, for which China committed financing in 2009, will alleviate water scarcity.
Responsibility of water supply in Nigeria is shared between three 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 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.
