Characterisation of Grey Water in Chiromo Campus




As pressures on freshwater resources grow around the world and the new sources of water supply become increasingly scarce, the need for new innovative ideas are required to address the challenge.  The reuse of domestic grey water for the irrigation of home gardens is quickly becoming widespread in many parts of the world. Research and development of in-house on-site grey water reuse may lead to significant reduction of domestic water consumption, and provide sustainable solutions to the national water economy. Thus it will contribute to the depleted national water budget.


The objective of this work was to identify and characterize grey water sources in Chiromo Campus. The research design included development of field questionnaires for identification and quantification of grey water sources in the campus, and field sampling and analysis of grey water to characterize grey water from different sources. This was performed in order to distinguish between different levels of pollutants in the grey water sources. Further evaluation was conducted to compare concentrations measured with those documented in the literature. The results indicated independent sources of pollutants depending on the activities conducted by different departments investigated. Most of the parameters measured were within the levels reported for grey water in the literature, illustrating that Chiromo Campus grey water can be treated for reuse providing a sensible approach for domestic water utilization that takes into consideration not only human needs, but also broad environmental aspects.


Key words: Water scarcity, grey water, grey water characterisation, Chiromo Campus
