The most exciting project that EWB-UCF is working on is building cisterns in Haiti. The Cisterns are going to be made of a composite ferro-cement material. The cisterns will be constructed using canvas molds as a giude. The mold will have steel mesh wrapped around it and then the steel mesh will be covered in cement. The inside of the cistern will also be covered with a safe, waterproof coating. This will result in a large and strong waterproof structure. There will also be a "first flush" system in place to discard the first few gallons of water that flow off of the roof in order avoid leaves and dirt flowing into the cisterns. Rain catchment systems like these have been implemented in many countries around the world and serve to help decrease our growing demand on limited fresh water supplies.

The cisterns will be filled from the runoff water from the roof of a church and also a rectory. Gutters will need to be installed along the roofs of both buildings to direct the water into the cisterns. The water from the cisterns will then be gravity fed to spigots at street level where it can be used by citizens. Almost all the materials used to construct the cisterns will be bought in Haiti. The only exception to that is the Canvas molds which will be made in the States.

The cisterns will each hold about three cubic meters of water which is approximately 800 gallons. This should allow the cistern to hold enough water to be able to dispense up to 50 gallons a day, every day of the year assuming an average amount of rainfall.
