Holding as many as twenty four-inch tablets of chlorine, the chlorinators we use in Port-au-Prince can treat 5000 gallons of water each day, thus helping stop waterborne diseases in Haiti. Most of our sites serve up to 10,000 Haitians by providing water to family members who stand in line with 5-gallon plastic buckets. When full, each bucket weighs forty pounds, a heavy burden for a child who totes one.
Design[edit | edit source]
Each Chlorinator treats 10% of the water going into the local tank by running it through the tablet chamber. That process puts enough chlorine into the water to treat the entire tank contents. We provide test kits with color-coded guides to measure the chlorine content regularly. Each device has a handle to change the flow and regulate chlorine levels.
The device has no moving parts and uses no electricity which makes the chlorinators appropriate for Haiti and other developing countries, where there is no electric source or it is undependable. In Port-au-Prince, the electricity is off for days at a time, and often on for only three or four hours.
Costs[edit | edit source]
Most of our 100 installations in the capital are LF500 devices shown in this illustration. A few are much larger such as our chlorinator in Jalousie which serves 50,000 people. The devices cost $40 and $100 depending on their size and come from the NOWECO Company in Ohio. Tablets cost $50 a year in the smaller chlorinators from Arch Chemicals
