In response to the Syrian refugee crisis, Sabri Farah International, in collaboration with Hamilton Kent, has developed sectional precast concrete sanitary collection tanks for the first time in the Middle East. SFI is currently executing 2,600 of such tanks for World Vision International under the umbrella of UNICEF at the Azraq refugee camp in Jordan. These tanks are guaranteed to be 100% watertight for 30 years. The low costs, very fast execution time, and the guarantee of zero contamination of aquifers as well as the highly diminished probability of outbreaks of cholera and typhoid makes SFI's sectional precast concrete collection tanks the new standards for water treatment, sewage collection and rainwater collection in both open circuit and closed circuit water projects in the Middle East.
