Water treatment with Chulli improved cooking stove in rural areas of Pakistan

This case study introduces tests completed in the province of Sindh in Southern Pakistan on improved cooking stoves known as Chulli. The Chulli enables water treatment through the use of a water heating mechanism. It is a cost-effective method for the households as the system is fitted into a stove meaning that water can be treated at the same time as cooking activities are completed. This reduces the need for firewood, itself an inhibitory cost of these poverty stricken communities that results in many not treating their water in any way. The trial was done for 5.000 households in Sindh with a focus on water quality, flow, fuel consumption, time and a cost analysis. The study in general found positive initial results in the water quality, as well as savings for fuel and time. However, the study needs to be followed up by a further study of ongoing usage.
