Charity: water is a non-profit organization founded by Scott Harrison. Charity: water provided drinking water to people in developing nations.
“1 in 10 people lack access to clean water. Charity: water on a mission to change that. Here’s how.”
In order to have a clean water, there are different type of solutions provided.
- Hand-Dug Wells
Skilled laborers dig up to 15 meters by hand to reach aquifers below. This is often the only relatively easy way to obtain water, particularly in developing countries that lack surface water.
It is an economical technique because it only requires physical labour with simple tools. This is the simplest method of well construction. Wells dug this way have a wider diameter which means water can be drawn from a wider zone in the water table.
These wells can capture water from less permeable materials such as fine sand, loam or clay.
- Drilled Wells
A drilling team drills deep into the earth to reach fresh aquifers. The advantages of drilled wells are the quicker and cheaper to sink than hand-dug wells, less susceptible to contamination, no de-watering during sinking required, less lining material required compares to hand-dug wells, safer in construction and use compared to hand-dug wells and the well itself barely needs maintenance as well as many simple drilling techniques available suiting most geological conditions
- Rainwater Catchments
Gutters on rooftops direct the flow of rainfall into a sanitary holding tank. Also called rain harvesting, these simple systems connect downspouts (gutters) to a central water tank capable of holding about 100,000 liters of water or more. Often, in dry countries, the issue is not that it never rains, but rather that when it does, most of the runoff is lost. These water systems make the best use of what little rain there is.
- Gravity Fed Systems
The force of gravity feeds water into a community from an elevated source. The gravity fed water system is used to pull the water from springs, streams, creeks, rain barrels, and rivers upstream or uphill from the water source. You can use this system to provide water to your shower, gardens, animal barns, and even your whole house if you have it set up properly.
- Water Purification Systems
Installed treatment systems remove contaminants from existing systems. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Water purification may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduce the concentration of a range of dissolved and particulate matter.
