Sewage disposal regulation and administration describes the governance of sewage treatment and disposal.
Water supply and sanitation in France is universal and of good quality. Salient features of the sector compared to other developed countries are the high degree of private sector participation using concession and lease contracts and the existence of basin agencies that levy fees on utilities in order to finance environmental investments. Water losses in France (26%) are high compared to England (19%) and Germany (7%).
Public water supply and sanitation in Germany is universal and of good quality. Some salient features of the sector compared to other developed countries are its very low per capita water use, the high share of advanced wastewater treatment and very low distribution losses. Responsibility for water supply and sanitation provision lies with municipalities, which are regulated by the states. Professional associations and utility associations play an important role in the sector. As in other EU countries, most of the standards applicable to the sector are set in Brussels. Recent developments include a trend to create commercial public utilities under private law and an effort to modernize the sector, including through more systematic benchmarking.
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;
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.
The Water supply and sanitation services in Portugal have seen important advances in access to services, technologies used and service quality over the past decades (1980s–1990s), partially achieved thanks to important funds from the European Union. Nevertheless, sanitation still remains relatively low in mountain rural areas and some people have their own sources of water controlled by municipalities.
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.
The water privatisation in England and Wales involved the transfer of the provision of water and wastewater services in England and Wales from the state to the private sector in 1989, through the sale of the ten regional water authorities (RWA). The potable water supply as well as the sewerage and sewage disposal functions of each RWA were transferred to privately-owned companies.
Public water supply and sanitation in Denmark is characterized by universal access and generally good service quality. Some salient features of the sector in the Denmark compared to other developed countries are:
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 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 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 Greece is characterised by diversity. While Athens receives its water from a series of reservoirs, some of which are located 200 km away, some small islands are supplied with water from tankers. Greeks have suffered from repeated droughts, the most recent one occurring in 2007. The EU supported the construction of numerous wastewater treatment plants since the 1990s in order to achieve EU environmental standards. While the wastewater discharge of the biggest cities is now in compliance with these standards, some smaller towns still lag behind.
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.
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 Italy is characterized by mostly good services at prices that are lower than in other European countries with similar income levels. For example, the average monthly residential water and sewer bill in Italy is 20 Euro compared to 31 Euro in France. According to the OECD, water in Italy has been underpriced for a long time. With about 240 liter per day, per capita water use for residential uses in Italy is higher than in Spain or in France, where it is about 160 liter per day. Water resources in Italy are distributed unevenly, with more abundant resources in the North and scarcer resources in the South. Most water withdrawals are for agriculture and industry, with only 18 percent of water withdrawals made for drinking water supply. About one third of the water withdrawn for municipal supply is not billed to the customers because of leakage, malfunctioning water meters and water theft.
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.
