Another important aspect of implementation is the regular monitoring and assessment of drinking water quality, both before and after new schemes have been installed. Responsibility for water quality is shared by the Ministry of Health (MoH) and the Ministry of Water, Irrigation and Energy (MoWIE), and their regional bureaus.
The MoWIE tests the water quality of proposed surface water and groundwater sources before undertaking the construction and commissioning of new schemes. In some parts of the country there are problems caused by the natural water chemistry such as high levels of fluoride, iron and salinity. The MoWIE is responsible for identifying these issues and implementing mitigation measures where appropriate.
The MoH is responsible for the periodic monitoring of water quality after water supply schemes are commissioned through its regional bureaus and woreda offices, testing the microbiological quality of the water to ensure the water is not contaminated and is safe to drink (Figure 10.9).
