Engineers Without Borders’ successful trip to Kenya

Publication date:

The EWB Kenya team worked with Haki Water Kenya to install a chlorination system in an under privileged school in Kayole-Soweto slum in Nairobi Kenya. The chlorination system is to treat ground water pumped from a borehole on the school compound with was hitherto high in total bacteria and faecal coliform levels (well above WHO and Kenya government standards). Students who drank the water therefore fell ill frequently and absenteeism due to water borne illnesses was a big problem in the school, with a poor effect on student performance. By project commissioning, the treated borehole water had nearly 100% less bacteria and conformed to international standards. The team also ensured that the chlorination system allowed for residual chlorine levels for treatment of any further contamination in the piping system before final extraction and use at the various water points in the school.
