Chlorine Dosing in Nyarugusu Refugee Camp

The Nyarugusu refugee camp in Tanzania is an excellent example of how Water Mission can provide reliable and sustainable safe water to people in need.

In its 23-year history, water in Nyarugusu has either gone untreated or has relied on manual mixing of calcium hypochlorite directly into storage tanks. This approach is unreliable, poorly controlled, and produces unwanted byproducts that settle in the bottom of storage tanks.

Even though deep drilled groundwater is typically safe to drink, Water Mission adds chlorine to avoid contamination after it leaves the tap stand. Since refugees living in the camp transport their water in plastic jerry cans or buckets, the chlorine residue provides added assurance by killing any bacteria that might find its way into the containers.

With a large demand for safe water from a camp population of approximately 150,000, Water Mission’s team in Tanzania has provided a large-scale, reliable, controllable, and efficient water treatment solution through chlorine dosing pumps. Nyarugusu refugee camp now sources all water exclusively using boreholes, some of which operate at a capacity of up to 85 cubic meters per hour (375 gallons per minute).
