Water supply and sanitation in Algeria
Drinking water supply and sanitation in Algeria is characterized by achievements and challenges.
 Among the achievements is a substantial increase in the amount of drinking water supplied from reservoirs, long-distance water transfers and desalination at a low price to consumers, thanks to the country's substantial oil and gas revenues.
 These measures increased per capita water supply despite a rapidly increasing population.
 Another achievement is the transition from intermittent to continuous water supply in the capital Algiers in 2011, along with considerable improvements in wastewater treatment resulting in better water quality at beaches.
 These achievements were made possible through a public-private partnership with a private French water company.
 The number of wastewater treatment plants throughout the country increased rapidly from only 18 in 2000 to 113 in 2011, with 96 more under construction.
 However, there are also many challenges.
 One of them is poor service quality in many cities outside Algiers with 78% of urban residents suffering from intermittent water supply.
 Another challenge is the pollution of water resources.
 There has also been insufficient progress concerning reuse of treated water, a government priority in this dry country.
Water supply and sanitation in Burkina Faso

 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.

 It is approximately 1.5 mi long, and on average 0.4 mi wide, though two arms of the lake combine to produce a width of 1 mi at the lake's center.

Water supply and sanitation in Belgium
Water supply and sanitation in Belgium is provided by a large variety of organizations: Most of the 589 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.
