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;
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.
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.
The Philippines' 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 privatization in Metro Manila began when the then President of the Philippines, Fidel Ramos, instructed the government in 1994 to solve what he called the water crisis in Manila by engaging with the private sector. In 1997, two concession contracts for the Eastern and Western halves of Metro Manila were awarded after an open competition. The concessions represent the largest population served by private operators in the developing world. Both winning companies, Maynilad Water Services in West Manila and especially Manila Water in East Manila, submitted bids with extremely low water tariffs. The tariffs proved to be too low to finance the investments needed to improve performance, especially after the East Asian financial crisis and the devaluation of the Philippine Peso.
Water supply and sanitation in the Netherlands is provided in good quality and at a reasonable price to the entire population. Water consumption is one of the lowest in developed countries at 128 litres per capita per day and water leakage in the distribution network is one of the lowest in the world at only 6%.
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.
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.
Greater Mexico City, a metropolitan area with more than 19 million inhabitants including Mexico's capital with about 9 million inhabitants, faces tremendous water challenges. These include groundwater overexploitation, land subsidence, the risk of major flooding, the impacts of increasing urbanization, poor water quality, inefficient water use, a low share of wastewater treatment, health concerns about the reuse of wastewater in agriculture, and limited cost recovery. Overcoming these challenges is complicated by fragmented responsibilities for water management in Greater Mexico City:
Water supply and sanitation in Belgium is provided by a large variety of organizations: Most of the 581 municipalities of Belgium have delegated the responsibility for water supply and sanitation to regional or inter-municipal utilities. There are more than 62 water supply utilities, including 2 regional, 30 inter-municipal and 30 municipal utilities. Another 100 mostly small municipalities provide services directly without having a legally of financially separate entity for water supply. Water is not scarce in Belgium and water supply is generally continuous and of good quality. However, wastewater treatment has long lagged behind and Brussels only achieved full treatment of its wastewater in 2007. In 2004 the European Court of Justice ruled condemning Belgium's failure to comply with the EU wastewater directive, and the ruling has not been fully complied with so far. Wallonia satisfies 55% of the national needs in drinking water while it counts only 37% of the population. Flanders and Brussels are dependent on drinking water from Wallonia, at a level of 40% and 98% respectively.
Water resources management in modern Egypt, is a complex process that involves multiple stakeholders who use water for irrigation, municipal and industrial water supply, hydropower generation and navigation. In addition, the waters of the Nile support aquatic ecosystems that are threatened by abstraction and pollution. Egypt also has substantial fossil groundwater resources in the Western Desert.
Water supply and sanitation in Morocco is provided by a wide array of utilities. They range from private companies in the largest city, Casablanca, the capital, Rabat, Tangier, and Tetouan, to public municipal utilities in 13 other cities, as well as a national electricity and water company (ONEE). The latter is in charge of bulk water supply to the aforementioned utilities, water distribution in about 500 small towns, as well as sewerage and wastewater treatment in 60 of these towns.
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.Charging for water used by agriculture has been suggested.
Water supply and sanitation in Malaysia is characterised by numerous achievements, as well as some challenges. Universal access to water supply at affordable tariffs is a substantial achievement. The government has also shown a commitment to make the sector more efficient, to create a sustainable funding mechanism and to improve the customer orientation of service providers through sector reforms enacted in 2006. The reform creates a modern institutional structure for the water sector, including an autonomous regulatory agency, an asset management company and commercialised state water companies that have to reach certain key performance indicators that will be monitored by the regulatory agency. The government has also stated its intention not to embark on new private sector contracts for water provision, after a bout of such contracts during the 1990s showed mixed results.
Water supply and sanitation in Japan is characterized by numerous achievements and some challenges. The country has achieved universal access to water supply and sanitation, has one of the lowest levels of water distribution losses in the world, regularly exceeds its own strict standards for the quality of drinking water and treated waste water, uses an effective national system of performance benchmarking for water and sanitation utilities, makes extensive use of both advanced and appropriate technologies such as the jōkasō on-site sanitation system, and has pioneered the payment for ecosystem services before the term was even coined internationally. Some of the challenges are a decreasing population, declining investment, fiscal constraints, ageing facilities, an ageing workforce, a fragmentation of service provision among thousands of municipal utilities, and the vulnerability of parts of the country to droughts that are expected to become more frequent due to climate change.
Water supply and sanitation in Lebanon is characterized by a number of achievements and challenges. The achievements include the reconstruction of infrastructure after the 1975–90 Civil War and the 2006 war with Israel, as well as the reform of the water and sanitation sector through a water law passed in 2000. The law created four Regional Water Establishments to consolidate numerous smaller utilities.
Water supply and sanitation in Nairobi is characterised by achievements and challenges. Among the achievements is the expansion of infrastructure to keep pace with population growth, in particular through the construction of the Thika Dam and associated water treatment plant and pipelines during the 1990s; the transformation of the municipal water department into an autonomous utility in 2003; and the more recent reduction of water losses – technically called non-revenue water – from 50 to 40%.
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.
Water supply and sanitation in Georgia is characterized by achievements and challenges. Among the achievements is the improvement of water services in the capital Tbilisi where the water supply is now continuous and of good quality, major improvements in the country's third-largest city Batumi on the Black Sea where the country's first modern wastewater treatment plant now is under operation, as well as a general increase in access to drinking water in the entire country. Water and sewer tariffs remain affordable, with the private water company Georgian Water and Power (GWP) serving the capital being financially viable and profitable, while the public water company serving most of the rest of the country remains financially weak. The improvements were achieved after the Rose Revolution of 2004 when the government decided to reform the sector and to invest in it after many years of neglect.
