Engineers Without Borders- Los Angeles Professional Chapter (EWB-LA) is developing an improvement project in Tanzania for the village of Lulindi’s existing tap water system. In 2015, EWB-LA went to Lulindi to build a French drain in order to provide an increased flow of water during the dry season into an already built catchment basin. This catchment basin is the main source of water for the village, and water is distributed to several taps that are installed throughout the village. Other bacteriological water quality tests presented obstacles because the village is in a remote area with no lab access and the terrain is steep, making it difficult to carry a lot of equipment for water quality testing.
EWB-LA used the CBT to identify a high level of E. coli contamination in the village’s main water source.
