The full cost of supplying water in urban areas in developed countries is about US$1–2 per cubic meter depending on local costs and local water consumption levels. The cost of sanitation (sewerage and wastewater treatment) is another US$1–2 per cubic meter. These costs are somewhat lower in developing countries.
In the United States, 44 million people used self-supply and private water sources in 2010 and about 22% of the rural population uses private wells to access groundwater for their water supply.

Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. According to World Bank, ″annual freshwater withdrawals refer to total water withdrawals, not counting evaporation losses from storage basins. Withdrawals also include water from desalination plants in countries where they are a ...
Many of the urban water supply networks in developing countries face problems related to population increase, water scarcity, and environmental pollution. Population growth. In 1900 just 13% of the global population lived in cities. By 2005, 49% of the global population lived in urban areas.
