Nairobi Dam and more

Today began with a visit to the Nairobi Dam, which is just downstream from Kibera. A developer is constructing an apartment building at the toe of the dam. The dam has collapsed and destroyed the construction stie twice so far, and now the developer is trying again. The dam holds back a reservoir of 100,000 m3. This post also includes photos from visits to KDI sites 1 and 3. Site 1 is the where we are designing a stream stabilization plan. Site 3 is currently in construction where red clay bricks are being produced.


Nairobi Dam reconstruction take 2. The Dam was recently rebuilt after two recent collapses. Building construction has resumed at the toe of the dam. If the trend of collapse continues, we can expect another in the rains of late October 2012.



The dam reservoir in the foreground with KDI’s site 1 multipurpose building across the reservoir. Althoug the reservoir may look like a field, it is covered in water hyacinth due to pollution. Before 20 years ago the reservoir was a lake used by the local communities for swimming, washing, and sailing. Now the water can’t be used.



The construction site below the dam. Good idea or bad idea?



Project Site 1 where we’ll being reconstructing the river banks with riprap and live plantings over the coming weeks.





The Ministry of Environment is responsible for maintaining the rivers, including the Ngong in Kibera. It was amazing to see how clean the river could become and how the river flow could change with reduced garbage clogging it.

Brick making at site 3.



The bricks are made of a mix of red soil, cement, and water. The bricks are pressed one by one on site.



After pressing, the bricks are laid to dry.
