Tandale is an administrative ward in the Kinondoni district of the Dar es Salaam Region of Tanzania. According to the 2002 census, the ward has a total population of 45,058 people. It’s the Second Ward under Community Mapping For Flood Resilience project to be mapped to OpenstreetMap. A lot can be observed from the last time this area was massively mapped on OpenStreetMap by The GroundTruth Initiative led by Mark Iliffe in 2011.

Settlement in Tandale has increased drastically making accessibility to clean water and proper sanitation a bit of challenge to overcome. Part of the ward is made up of a public open market “Sokoni” (Swahili Ward for Market) which supplies community people and beyond with food supplies like fresh vegetables and dry grains. With this activity in place disposal of waste material is not properly monitored leaving it up to the rain to sweep away what is left behind to places vulnerable to such material (Residential Houses).

We may not only blame that to being the lead cause of floods in Tandale, also the poorly planned structures/ buildings which are closely built next to another trapping the constant flow of water to bigger water channels. Stagnant contaminated water has found its home in Tandale in addition to that, the road surfaces are ground and muddy trapping water instead of leading it to major water streams.

Constant blockages of drains in Tandale have also become contributors of floods in case the rains are heavy. Lack of proper disposal points of plastic material and paper bags in conjunction with loose eroded soils from unpaved roads.

This and more, yet to be discovered have made Tandale a water logged area which may become a breeding area for numerous water born diseases like Typhoid, Cholera and Diarrhea caused by poor sanitation structures and behaviors.
