In the past years, the low-lying area around the Nyabugogo river in Kigali has frequently been affected by flooding. Most of the floods happened when it rained heavily in March and April or September and October.
There are several reasons for these floods : the rainwater flows down the hills where only little vegetation is left for slowing it down and the drainage system is not equipped for vast amounts of water.
In some cases, the canals were blocked with garbage that stopped the water from being drained away. So the water rises in the streets and enters buildings, causing damages to cars, businesses and households in the area – even endanger-ing peoples’ lives. During heavy rain the river and the wetland already hold so much water that
they can hardly absorb the water from the streets and hills.
