Recently there have been floods on the roads of Nairobi. Not that there are no drainage systems along the road but because I’ve come to notice something about it… human irresponsibility. Trash is being damped on the road by motorists and the passers-by drop them along the road. On the dry season this may not look like something tragic but to say, oh this place is dirty! But all changes when it starts raining heavily. Upon heavy rains, the soil gets saturated enough to absorb any more water. This leads to pools of water being formed and eventually small streams. Basically, water flows downwards along gravity and drainage systems are best suited in managing water clogging.

As this small streams intersect down the slopes into the drainage channels, the small chunks of plastics get carried along with it. Too much accumulation of it in the drainage lines lead to blocked drainage resulting in water overflow and eventually flooding on the roads or streets.
Much of it has been addressed by environmentalists and taught in schools about waste management and control. It’s sad that people have become arrogant about it and we’re now facing the consequences. Flooding due to human activity is controllable. Let’s not blame the rains. Don’t dump wastes in the environment expecting someone to come and collect it for you. Take responsibility and some of this things will come to change for the better.
