China's fresh water resources include 2500 cubic kilometers of mean annual run-off in its rivers and 828.8 cubic kilometers of groundwater recharge.As pumping water draws water from nearby rivers, the total available resource is less than the sum of surface and groundwater, and this is only 2,821.4 cubic kilometers. 80% of these resources are in the South of China.

Financing. Out of the $4.7 billion of investments in water supply and sanitation in sub-Saharan Africa, 70% is financed internally and only 30% is financed externally (2001-2005 average). Most of the internal financing is household self-finance ($2.1bn), which is primarily for on-site sanitation such as pit latrines.
With rising demand, the quality and supply of water have diminished. [7] Water use has been increasing worldwide by about 1% per year since the 1980s. Global water demand is expected to continue increasing at a similar rate until 2050, accounting for an increase of 20–30% above 2019 usage levels. [6]
Water resources and use. The major river in Ethiopia is the Blue Nile. However, most drinking water in Ethiopia comes from ground water, not rivers. Ethiopia has 12 river basins with an annual runoff volume of 122 billion m 3 of water and an estimated 2.6–6.5 billion m 3 of ground water potential.
The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater. Of the freshwater, only 0.3% is in liquid form on the surface. [ 2][ 3][ 4] Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space ...
Water in this saturation zone is called groundwater. [9] Contamination of groundwater causes the groundwater water supply to not be able to be used as a resource of fresh drinking water and the natural regeneration of contaminated groundwater can take years to replenish. [10]
September 15, 2005: Ahmadinejad stated at a United Nations high-level summit that Iran has the right to develop a civil nuclear-power program within the terms of the 1970 treaty on the non-proliferation of nuclear weapons.

In 2015, 98% of the total population in Vietnam had access to "improved" water, or 99% and 97%, for the urban and rural population, respectively. That means that around 2 million people lacked access to "improved" water. Regarding sanitation, 78% of the population in Vietnam had access to "improved" sanitation, or 94% of the urban population ...
