Every Flood in Kampala Is a Waste Management Report Nobody Filed

The channels do not fail because the rain is unprecedented. They fail because of what is in them.

Rainfall intensity in the capital has increased, but the flood line moves fastest where collection is weakest. Traders in the affected markets can name the blockage points before the water arrives.

Collection, not campaigns

Awareness drives are cheap and visible. Scheduled collection in unplanned settlements is expensive and invisible, and it is the variable that actually correlates with what ends up in the channel.

We sweep, we sort, and then there is no truck. So it goes into the water.

Recycling aggregators say the material has value once it is separated at source, but the collection economics only work where households are within reach of a paid route.

The economics of a truck that does not come

Solid waste collection contracts in Kampala's denser parishes are structured around a route and a schedule. Both break down where roads are too narrow for a collection vehicle or where a settlement grew faster than the route was ever designed to serve. KCCA officials concede that unplanned settlements are the hardest and most expensive stretch of any collection contract, which is exactly why they are collected least reliably.

Private aggregators who buy sorted plastic for recycling say the material has real value once separated at source. And thata functioning collection route can pay for a portion of itself through resale, but only where households are close enough to a paid point to make sorting worth the effort.

People will sort if a truck comes reliably. Nobody sorts for a truck that skips two weeks and then blames the flood on littering.

NEMA has flagged single-use plastic packaging as a recurring blockage material in channel inspections. Enforcement of restrictions on the thinnest gauge bags has been uneven across divisions, with traders reporting inconsistent application at different market entrances.

The rains due later in the year are the test district engineers are bracing for: whether pre-season clearing this time reaches the informal settlements as well as the arterial channels that get photographed after every flood.
