Water-borne illness and death, which affects hundreds of millions of people around the world, is largely caused by drinking contaminated water. Preventing pollution from entering drinking water sources is the first step in fixing this problem.
Water pollution enters water systems from on-land sources through runoff after rain events, infiltration through the soil, and through poor management of human-related waste. The primary cause of waterborne illness and death occurs when drinking water becomes contaminated by human fecal waste (sewage), which happens predominantly when inadequate waste management systems exist and/or when there is a lack of multi-tiered water treatment facilities.
The World Health Organization (WHO) considers rainwater an improved drinking water source since it lacks exposure to the majority of on land-based pollutants.
Gravity Water focuses on prevention by exclusively using rainwater as the source of drinking water for each Clean Water System created. The Clean Water Systems built by Gravity Water direct rainwater from on-site rooftops to elevated storage tanks, preventing the water from ever coming in contact with the ground where water faces the greatest risk of pollution. Using a closed system, the rainwater is captured, diverted, and stored before 99.9% of harmful bacteria contamination can take place. After capture and storage, Gravity Water filters the rainwater using sub-micron filtration, virtually eliminating any potential living and non-living pollutants that may have entered the water source prior to storage.
Because Gravity Water’s Clean Water Systems store harvested rainwater in elevated tanks, gravity is the only required energy to provide filtration, eliminating the need for access to electricity or pumps.
