Gravity Water systems are the only approach to safe drinking water access that combine treatment and prevention into a single system.ġ00% Locally Owned - Gravity Water’s Local Ownership Program Through harvesting rainwater and storing it above ground, Gravity Water systems provide pressure for filtration without the dependency of electricity, which is commonly lacking in rural areas, or pumps, which are commonly the first thing to break in water systems and the reason 6 out of 10 wells are currently inactive in Africa. WATER NO GRAVITY LONDON DISPERSIO FREEHowever, there is one free energy source that can be used anywhere on earth, Gravity. In addition, electricity is usually needed to treat water, through powering sterilization or creating pressure for filtration. Electricity is used to pump water from a source (river, spring, groundwater, etc.) to where it needs to be used by the community however, many communities rely on “fetching” water, since pumping and electricity aren't available or reliable. One of the greatest challenges that communities in developing countries face in regards to water access is access to a reliable source of electricity. However, introducing rainwater catchment systems, that are provided for to the communities, will be culturally adaptable for communities using water tanks, since it is only introducing an augmentation in the process instead of a whole new system. This could be for many reasons, including a lack of resources to create a new system or a lack of access to individual rooftops. Unfortunately, many communities don’t practice rainwater catchment on a large basis. Increased Adaptive Capacity to Climate Change : According to studies conducted by the Intergovernmental Panel on Climate Change, “extreme precipitation events over most of the mid-latitude land masses and over wet tropical regions will very likely become more intense and more frequent by the end of this century…”.Ĭulturally Assimilative : Many developing countries throughout the world are currently using water tanks for storage, yet this is most commonly used to store groundwater or surface water through pump systems. Gravity Water works with each community to determine their current water access and meet their water consumption needs, year-round. Many areas around the world, such as the tropics, undergo year-round to seasonal rainfall patterns. Long-term Water Storage : Storing rainwater allows people to utilize rain events to provide a clean water source for extended periods, lasting anywhere from months to whole seasons. In contrast, nearly all groundwater and surface water sources require electricity to raise the water above ground level or create pressure for filtration. Since fecal bacteria from human waste isn’t commonly found on roofs, rainwater harvesting and sterile storage largely prevents contamination from taking place.Įnergy-free Storage : Gravity Water's systems store rainwater approximately two meters (six feet) above ground, providing potential energy for filtration through using gravity. Unlike groundwater, rainwater isn’t at risk of significant contamination until it reaches the ground where most harmful pollutants exist this is why the World Health Organization considers rain an “ Improved Drinking Water Source”, opposed to unprotected wells and surface water. The Earth has been filtering water for billions of years through the “water cycle”, turning water on the Earth’s surface and in the ocean’s into fresh rainwater through evaporation and condensation. The problem that most of communities face is not a lack of access to fresh water, but water pollution and contamination (most commonly from sewage and fecal bacteria), making the water they have unsafe to drink. Did you know the vast majority of people who don’t have access to safe drinking water around the world live in the Tropics and Sub-tropics? 2 billion people around the world still depend on a contaminated water source, even though the majority live in places where fresh water is abundant.
