The water industry provides drinking water and wastewater services to residential, commercial, and industrial sectors of the economy. Typically public utilities operate water supply networks. The water industry does not include manufacturers and suppliers of bottled water, which is part of the beverage production and belongs to the food sector.
Issues that affect drinking water supply and sanitation in the United States include water scarcity, pollution, a backlog of investment, concerns about the affordability of water for the poorest, and a rapidly retiring workforce. Increased variability and intensity of rainfall as a result of climate change is expected to produce both more severe droughts and flooding, with potentially serious consequences for water supply and for pollution from combined sewer overflows. Droughts are likely to particularly affect the 66 percent of Americans whose communities depend on surface water. As for drinking water quality, there are concerns about disinfection by-products, lead, perchlorates and pharmaceutical substances, but generally drinking water quality in the U.S. is good.
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.
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.
Water supply and sanitation in Indonesia is characterized by poor levels of access and service quality. Over 40 million people lack access to an improved water source and more than 110 million of the country’s 240 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 is the process of providing water in a systematic way through installed pumps and pipe lines. Before water is provided to a specific area, it undergoes a process called sanitation to ensure that the quality of water received is safe for human consumption. The Philippines’ water supply system dates back to 1946 after the country achieved its independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge in the operation and administration of water supply and sanitation in the country.
Drinking water supply and sanitation in Benin has been subject to considerable progress since the 1990s, in particular in rural areas, where coverage is higher than in many other African countries, and almost all development partners follow a national demand-responsive strategy, which has been adopted in 1992. New strategies to increase water supply in rural and urban areas have been adopted in 2005 and 2006. Tariffs in urban and rural areas are usually high enough to cover the costs for operation and maintenance.
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 services in Ireland are governed primarily by the Water Services Acts of 2007 to 2014 and regulated by the Commission for Energy Regulation. Until 2015, the relevant legislation provided for the provision of water and wastewater services by local authorities in Ireland, with domestic usage funded indirectly through central taxation, and non-domestic usage funded via local authority rates. From 2015, the legislation provided for the setup of a utility company, Irish Water, which would be responsible for providing water and wastewater services, and funded through direct billing. The transition between these models, and certain aspects of operation of the new company, caused controversy in its initial period of operation.
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.
As the country's supply of freshwater is increasingly vulnerable to droughts, possibly as a result of climate change, there is an emphasis on water conservation and various regions have imposed restrictions on the use of water.
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 1990 and 2010 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 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, and two other cities, 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.
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.
