Of all municipal services, provision of potable water is perhaps the most vital. People depend on water for drinking, cooking, washing, carrying For example, household water treatment methods, such as boiling or chlorination, were found to be effective, especially in the acute emergency context Other useful point‐of‐use water treatment technologies include dilute hypochlorite solution, porous ceramic filtration, and combined flocculant‐disinfectant powdered mixtures 7.

The cost and environmental side effects of these compounds has increased interest in the use of organic coagulants derived from plant material, such as Moringa oleifera (MO) seed (Jahn and S.A.A.,Jahn, ; Olsen, ; Sutherland et al., ; Muyibi and Evison, a, Muyibi and Evison The primary aim of this study was to undertake an extensive field water quality-sampling programme in rural villages throughout Malawi.

Currently, million people live without access to safe water and billion live without adequate sanitation. When we talk about Water resources assessments (WRAs) are designed to be analyses of available water sources from the perspective of potential water use.
