For the current El-nino rainy season, Kampala has as quite often flooded with a number of areas impassable after a heavy downpour making navigation and accessibility rather hard for not only pedestrians but also motorists.

But most of the problems are attributed to human activity and what it looks like is mindset change that is needed to rather solve a bigger percentage of the flooding and drainange challenges of the city as the planners rethink the city design.

Kinawataka swamp alone currently has  63 freehold titles according to information  min of lands. That not withstanding, there has been massive encroachment on the water pathways and natural filters for flood run offs with people building over drainage channels and water ways plus swamps.

Indeed the bigger question one would immediately ask is are the relevant authorities including Kampala capital city authority ( KCCA) sleeping on job? Another will also ask who is behind these “bigwigs” that destroy the environment in broad day light.

According to the Kampala drainage master plan  , Kampala is drained by 9 main drainage systems (primary channels served by numerous secondary and tertiary systems) with a total catchment area of 278.71 km2 . These include Lubigi,Nakivubo, Kansanga, Gaba,Nalukolongo, Mayanja, Kinawataka, Nakalere, Walufumbe, Nalubaga and Mayanja North.

However Human settlement and industrial development are extending from the many hills within Kampala City to the lower lying areas on the banks of the drainage channels which are part of wetlands and floodplains.

The master plan highlights frequency of flooding increased in recent years  attributed to

Increased runoff caused by climate-related and land use changes in the catchments, reduction of the buffer capacity of wetlands due to encroachment, frequent disposal of solid was in open storm water channels leading to blockage,  Inadequately design and constructed road side drainage channels and culverts among others.

For now, KCCA can only do much including , building  non open air drainages/trenches (Closed)  whose Inlets have wiremesh and other barriers deterring disposal of solid waste into the channels, creating  box culverts for confluents  i.e areas that are joineries for various channels for example around Munyonyo Auto spa that joins Ggaba, Munyonyo, Buziga water run off among others.

But, just how sustainable is this?
