Design Specifications

Gravity Water installs rainwater harvesting systems unique to each project and country. Each system is installed with a three-tier filtration system. Pre-filtration first takes place with a 5-micron carbon block filter to remove microbes and particulates. A second 5-micron carbon block filter provides secondary filtration to this end. Finally, a 0.1-micron hollow-membrane water filter is used to remove the remaining microbial life. Each design is custom-made.
